Does anyone have any ideas for a topic?

--Z3466260 (talk) 18:45, 24 March 2015 (EST) hi guys, hope everyone is ready for this assignment :) just wondering, did we have any preferences as to what part of the ECM we will be doing our assignment on? maybe we can do something like...communication of cells? im not sure what Mark is looking for :P]

--Z3459592 (talk) 14:23, 25 March 2015 (EST) Im not sure if we can do communication of cells although it would be good. From what i've read only other topics i can think of are


- cell migration

- formation of the ECM

- Why is the ECM essential for healing


Only problem with these is im not sure if there would be enough information for this assignment. Any other suggestions?

--Z5049401 (talk) 16:43, 25 March 2015 (EST) In lecture he mentioned the topic of collagen, I wonder if the topic of elastin would be too broad or too popular?

--Z3466260 (talk) 20:47, 25 March 2015 (EST)oh, im really really interested in the "why ECM is essential for healing" ! that sounds like an awesome topic to do! does anyone else agree, or can suggest any other? im keen with anything really :)

--Z5049401 (talk) 13:12, 26 March 2015 (EST)That topic sounds good to me.

--Z3466260 (talk) 14:35, 26 March 2015 (EST)cool, how do we let mark know then? and see you guys in the lab :P

--Z5049401 (talk) 17:44, 26 March 2015 (EST)What about integrins?

--Z3466260 (talk) 17:23, 27 March 2015 (EST)hey guys, ive encountered a pretty big problem in terms of disease for integrins, there arent any diseases that are directly related to it, or any diseases caused by a loss of function between integrins and the ECM, i need a new topic asap to research....

--Z3459592 (talk) 10:02, 29 March 2015 (EST) hmmm maybe synthesis? im thinking we are going to need a whole new topic all together since it is going to be hard to link it to the ECM

--Z3466260 (talk) 13:13, 29 March 2015 (EST)well 1, people aren't really checking this as often as I am at least lol...and even if we change topic we can't let them know efficiently enough. I could try synthesis..ill let you know

--Z5049401 (talk) 14:20, 30 March 2015 (EST)hey, I've found a couple of articles that talk about how integrins are a contributing factor to epidermolysis bullosa in humans and mice, http://www.ncbi.nlm.nih.gov/pubmed/8673141

--Z3466260 (talk) 11:20, 1 April 2015 (EST) Hey guys just an update for you - unless I find definitive info on diseases related to integrins, I'll be submitting the lab assessment as an intro - so I'll be doing general research and also connecting the function of integrins with the ECM :) hope thats okay - though a warning is that we may need to change topics depending on if I can find something to do...its hardly fair if i just do an intro, so we'll discuss this tomorrow in the lab :)

--Z3459592 (talk) 17:59, 1 April 2015 (EST) sounds like a plan, this article seems decent for structure of integrins from what i've read skimming through it <pubmed>10961914 </pubmed>

Integrin traffic – the Update

A5B1&a2B1 Integrin Trafficking.jpg

This article [1]discusses the complex topic of integrin trafficking and the important role it plays in the endocytic and exocytic maintenance and recycling of integrin-ECM adhesions that anchor the ECM to the plasma membrane. It also identifies the role that focal adhesions play in maintaining connections to the ECM. The role that cholesterol plays in regulating these focal adhesions is also discussed.


Static stretch affects neural stem cell differentiation in an extracellular matrix-dependent manner

This article[2] tackles the role that integrin-laminin interactions play in the ECM and how external mechanotransduction influences the fate of stem cell differentiation. It also discusses the role that integrin play as mechanosensors for the cell, and how static stretch plays a influential role in the differentiation of stem cells. The paper concludes with stating that further research into the role that laminin integrin and laminin serve as a mechanosensor.


Vascular Smooth Muscle Cell Stiffness and Adhesion to Collagen I Modified by Vasoactive Agonists

This article[3] discusses how integrins, specifically collagen binding integrins, play a key role in the contraction of vascular smooth muscle cells. Furthermore, the researchers hypothesize that integrin-collagen adhesion is regulated by the initiation of contraction within vascular smooth muscle cells. The paper’s findings suggest that it is the integrin adhesion sites that provide sound stability for the contraction of vascular cells.


Tumor Angiogenesis in the Absence of Fibronectin or Its Cognate Integrin Receptors

This article[4]discusses the possible role that integrin and fibroconectin binding to the ECM could contribute to cell growth, and cancer growth specifically. The researchers studied the critical roles that integrin and their association with ECM fibronectin proteins play in mouse embryo development. The researchers concluded that integrin interactions are completely necessary for tumor angiogenesis in mice.

--Z3466260 (talk) 12:35, 3 April 2015 (EST)nice work :) i found something to do with integrins and their interactions with the ECM to determine the movements of cancer :D sound good? Integrins and cancer: regulators of cancer stemness, metastasis, and drug resistance.[1]

--Z3466260 (talk) 14:52, 3 April 2015 (EST)====Role of Integrins in Disease: Case Study====

Integrins and cancer: regulators of cancer stemness, metastasis, and drug resistance (Review) [2]

This article shows the interactions between the integrins on cell surfaces with the environment - the extracellular matrix and their role in cancer and their metastasis. Integrins have multiple types of receptors derived from various combinations of their alpha and beta units, and tumour initiating cells present integrins like alpha 6, beta 1 and 3 on their cells, which are usually only present on stem cells. This means that they can self regulate proliferation and even differentiation. However different integrins being expressed on the cancer cells also allow them to survive in areas which are usually out of bounds, i.e. outside of the ECM, and this provides some understanding as to how cancer cells survive and proliferate during dissemination in the blood and metastasis. Integrins assist in tumour progression and drug resistance through their interaction with the ECM, where the ECM can regulate cell sensitivity to therapies.

Variety in the tumor microenvironment: integrin splicing regulates stemness [3]

This article focuses on the findings of expression in integrin subunits α6B and α6A and its relationship with the development of triple negative breast cancer. It is implied that ESRP1 (epithelial splicing regulatory protein) levels affect the expression of integrin α6B, which possibly promotes anchorage independent growth of tumours, resulting in metastases. The important of integrin expression is reinforced in this article, and current research targets the genes that make TICs or the general population express TIC like features.

Tissue mechanics modulate microRNA-dependent PTEN expression to regulate malignant progression. [4]

MiRNA affects integrin dependent adhesion, and the stiffness of the ECM subsequently affects the levels of mature MiRNA in a cell. In particular, it is discussed the MiRNAs play an essential role in tumour mechanics, where integrins are the facilitators of change in expression. Specifically in mouse breast cancer, we see that miR-18a regulates the maligancy of breast cancer by targetting the tumour suppressor PTEN. The effect of the ECM in regards to the metastatic potential of a tumour can be seen to interact with the actions of integrins on cancer cells.

Integrin activation controls metastasis in human breast cancer. [5]

It is seen in breast cancer cells that integrins can bind to platelets in the bloodstream, therefore alluding to the possibility of metastasis. The activated αvβ3 integrin allows for breast cancer cells to do so, and therefore the expression of this integrin on cancer cells indicate the potential for metastasis. It is not however a definitive factor for metastasis, but has an essential role in cancer cells metastasising through blood dissemination.

The Role of integrins in the trabecular meshwork

This paper[6] is about the role of integrins and how they can control the function of the trabecular meshwork. Integrins are known to promote adhesion to the ECM however they are not just adhesion receptors they act as conduits to convey information about the ECM. This signalling regulates many processes of the trabecular meshwork such as growth factor and cell death. There are many different types of integrins in the trabecular meshwork, and this paper found that they are likely to have unique and specialised functions.


Molecular Biology of the Cell. 4th edition.

This book [7] talks in general about what integrins are, structure, signalling and how they interact with the cytoskeleton.


RGD and other recognition sequences for integrins (review)

This review [8] looks at how the discovery RGD by ruoslahti has lead to a large number of pharmaceutical applications explaining how it binds and the importance of cell adhesion.


The emergence of integrins: a personal and historical perspective

This article [9] discusses what lead to the discovery of intergrins. Serveral investigations help lead to its discovery including; the investigation of fibronectin structure, monocolonal antibodies that had been raised against chicken myoblasts. The investigation of the fibronectn lead to a small fragment of fibronectin that promotes cell adhesion which is RGDS. The monocolonal antibodies lead to CSAT and JG22 being discovered which interfered with myoblast adhering to the matrix. From this Hynes deduced that the CSAT and JG22 antigen was the molecule which links the myoblast to the matrix.


http://sciencewatch.com/nobel/predictions/cell-adhesion This article is on the history of integrins. It states that Richard Hynes and his group discovered and named the protein 'intergrin' which connected fibronectin to actin in the cell wall. While Ruoslahti identified RGD peptide (a small fragment containing a sequence of 3 amino acids) which is a vital recognition sequence in the integrin family. Both are accredited for its discovery.


intergrins (review)

This review [10] which provides the basic facts about integrins hence why I dot pointed for future reference when we do the actual page :)

- cell adhesion receptors

- The name integrin was given to indicate the importance of these receptors for maintaining the integrity of the ECM.

- RGDS peptides enabled us to see that functional receptors of intergrins are heterodimers

- composed of alpha and beta subunits which are non-colvalently associated

- grouped based on ligand binding properties

- alpha subunit determines which ligand it binds

- alphaI domain - inserted domain ~200 amino acids

- Beta subunit connects to cytoskeleton

- integrins can exist in a compact bent conformation

- links ECM and cytoskeleton, mostly actin cytoskeleton

- by-directional signaling receptors

This picture shows the structure of an integrin on both sides

--Z3459592 (talk) 11:21, 22 April 2015 (EST) we need to start doing work for this assignment guys, pretty sure he is checking it either this week or next week and he can't really check it if nothing is there :/


--Z3459592 (talk) 12:29, 22 April 2015 (EST) does anyone know the coding of how to manually enter the reference? one of my references is a book on pubmed and the pmid doesn't work

--Z5049401 (talk) 17:23, 22 April 2015 (EST) We might be able to use this is our last section on cancer. https://youtu.be/fwhpfv2JUCM

--Z3415735 (talk) 17:52, 23 April 2015 (EST) Hey guys, sorry I could not make it to the lab today. I did go to my morning classes, but I've been sick the past few days and had to go home early today. I uploaded work on the structure of Integrins last week before our last lab. I will definitely be there next week, and I'll keep updating my section of the wiki page over the weekend.

--Z3459592 (talk) 18:06, 23 April 2015 (EST)

what mark said in lab 6

- something interesting at top of page

- balance between text/visuals (videos,pictures,tables)

- when you use references on project page - it must refer to the research article, you can use review just ensure you say "in the review" but the original research article is preferable

- graphical rep. of number of research on the topic comparing years of how many

- timeline

- where research is going - read current research

- all text about a figure does not need to be on the page, he will go through all photos to make sure you have all the correct information

- request for reuse

- lots of pretty pictures

--Z3415735 (talk) 19:40, 26 April 2015 (EST) Here's a great article I found on Integrin structure and function. I'll have a read of it tomorrow and will see if we can use any of the info on it for our page http://www.springer.com/cda/content/document/cda_downloaddocument/9781441908131-c1.pdf?SGWID=0-0-45-867678-p173905705

--Z3466260 (talk) 11:30, 28 April 2015 (EST)well, we really got to get a wriggle on guys. I hope by next lab (please check this page every day) that we get some substantial work done - im going to be spending my day doing this, so i would REALLY like to see more in the function and structure area >< especially the one with just a picture...

--Z3459592 (talk) 20:14, 28 April 2015 (EST) does anyone know how to use the same reference without adding an extra refence down the bottom because atm 3 and 4 are the same

--Z3459592 (talk) 13:08, 29 April 2015 (EST) guys if you find any major events which has happened for integrins such as integrins discovered, structure understood post it under timeline and i can make a picture for it :)

--Z3459592 (talk) 14:01, 29 April 2015 (EST) does anyone have any ideas why the structure subheading and its picture is going underneath the two graphs i just posted? i tried to increase the gap between but its still not happy :( thoughts?

--Z3459592 (talk) 18:00, 29 April 2015 (EST) he said he wanted us to use a table in lab 6 im pretty sure so maybe we should put a glossary in of terms at the end?

--Z3415735 (talk) 22:16, 29 April 2015 (EST) Hey guys, I've updated my section (Structure). I've put the image on the right in a thumbnail which makes the section a bit clearer and easier to navigate. I've also added some basic textual information on the structure and interactions of Integrin. I still need to add the reference for this information (http://www.ncbi.nlm.nih.gov/books/NBK6259/#A64068). I plan on going into more detail for structure, probably adding another 1 or 2 images to show the exact structure. The structure is quite complex though, I'm not entirely sure how much detail I should go into, because to be honest, we could do the whole project on structure alone! In addition I'll talk briefly about the discovery of Integrins and what techniques were used i.e. Xray crystallography

--Z3466260 (talk) 16:35, 30 April 2015 (EST) how is it synthesised? how is it regulated?

--Z3415735 (talk) 16:41, 30 April 2015 (EST) article on structure of integrins http://www.bloodjournal.org/content/102/4/1155.long?sso-checked=true

--Z3466260 (talk) 17:12, 30 April 2015 (EST) tools they use in the research

--Z3466260 (talk) 17:36, 30 April 2015 (EST) so what i mentioned that should be discussed

- how are integrins produced? dna, ER, Golgi, how is the expression of some integrins controlled? do all cells express all integrins?...what functional differences?

- how integrins get into the membrane

- integrin - actin interaction

- integrin RGDS ? whats that

- functionally important to put all these together :D

--Z3415735 (talk) 17:54, 30 April 2015 (EST) use an integrin as an example and dissect it. talk about each component

--Z3466260 (talk) 15:18, 3 May 2015 (EST)I was wondering if i should integrate e-cadherin dysfunctionalities - basically e cadherin does the cell-cell adhesions, but it interacts with integrin-ECM adhesions to induce tumour like properties...too much?

--Z3466260 (talk) 14:35, 5 May 2015 (EST)hey guys, i know we're all busy with uni, but i'd REALLY, like to see some work getting done. this page hasnt changed since last lab, nothing but what ive added to my research

--Z3415735 (talk) 18:51, 6 May 2015 (EST) yep, I will update some of our page now for structure. I found this article, which seems to explain the role of specific integrin alpha4beta1 in fibronectin assembly and cell motility. I think this was one of the things Dr. Hill was talking to us about last lab. http://jcs.biologists.org/content/108/2/821.long I'll see what I can add to my structure section from the article, but it could also work in the function section

--Z3415735 (talk) 19:20, 6 May 2015 (EST) ok guys, I updated my section (structure). I've split the heading into 3 sub headings (for now) and will continue to add more information during the week and weekend. I also added a 3rd image on structure which shows the exact biochemical structure of Integrin. What i'll probably work on next is to use a specific Integrin as an example, and go through its structure in detail, as each Integrin has its own unique structure apart from the general structure that all Integrins share

--Z3415735 (talk) 16:45, 7 May 2015 (EST) http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1302484/pdf/11751331.pdf i'm going to be using alpha4beta1 integrin as my example for structural analysis http://journal.frontiersin.org/article/10.3389/fimmu.2012.00242/full

--Z3459592 (talk) 14:00, 11 May 2015 (EST) Is that graph better? / is my drawn picture okay? i just did a quick job considering peer review is soon

--Z3415735 (talk) 17:25, 13 May 2015 (EST) the graph is great, and so is the drawing! its very clear and easy to understand

--Z5049401 (talk) 11:10, 14 May 2015 (EST) I agree! Also, does anyone know where the worksheet Dr. Hill is talking about for the Lab 7 Individual Assessment?

Group 2 peer review

Good use of hand drawn image to show how the integrins interact with the other proteins, however maybe make it a bit bigger so it is clearer and could have been better if there was a bit of colour in it to make it more eye catching. It corresponds with the adjacent text which is also informative and provides a good introduction to the topic. For the history section, you have used text to describe the events but instead it may be better presented as a drawn timeline or as a table so it is clearer and much easier to follow, but it seems as though you guys are in the process of making a timeline with dates anyway which looks good. Also good graph showing the levels of interest in integrins, really good to visualise.

Good diagram in the structures section, but maybe give reference to it i.e. figure 1, when talking about the fact there is an a and b subunit in the text, because you’ve referenced it when talking about the different configurational states which is good. Also, really good use of the animation but maybe some reference to it would be good. The diagram of the 3D structure of integrin is good but maybe moved up a bit in the structure section. The section on structure is the most eye catching and has good amounts of diagrams and lots of information which isn’t in block text which is good! For the final section about disease, it appears that there is lots of information there which is good however it is in block text and a few diagrams/images/images should be inserted here or use subheadings to split it up and keep the reader’s attention.

Overall, so far the page looks good, just requires touching up and a few more diagrams/images which I’m sure will be put in!

Group 2 peer review

The page is looking very well so far. However, I think there is still quite a lot of information that needs to be added for example in the time line section and future research. I also think that maybe you should consider joining the ‘discovery’ subtopic with the ‘timeline’. It might be more coherent that way. Some of the referencing is lacking for example in the ‘structure’ section but that can be added in later.

It is good that you drew a picture of how integrin react with other proteins. The diagram is well done and easy to understand. The introduction also does provide a brief overview of what integrins are which is helpful when you start browsing the page. The addition of the video is also very helpful in understanding integrin’s interaction with the ECM.

I would suggest that you add a couple of pictures to the ‘role in diseases’ possibly illustrating the clinical manifestations of the disease. It might make it more interesting. In general, I think there is still some parts to edit over and fix up but overall I think is a very good start.

Group 2 Peer Review

Overall, I thought this was a very strong web page. There was a good amount of in-depth information on your topic and most of it was well-written. The Structure section was well analysed and the photo provided a good visual aid. I am interested in understanding the rest of integrin specificity when it is finished. I thought the video was a good addition, however, it moved through the process very quickly and the words weren't up on the screen long enough to read. I had to re-watch it to see what was written. Plus, there was no sound. I'm not sure if that was intentional or it could just be my computer. Nevertheless, I think sound would be beneficial.

There were grammatical errors throughout the webpage, as well as, issues with sentence structure. Re-reading through the webpage would be beneficial. Also, there were multiple times that the word, integrin, was capitalized where it was not the beginning of the sentence. I do not think that capitalization is needed in these cases.

Additional info on integrin relationships with fibronectin, collagen, and laminin would be beneficial for the reader to gain a better understanding about the functions of integrins with other ECM components. The Role of Integrins in Disease section was well-written and gave significant information about each role of integrins. This section was the strongest in my opinion.

Group 2 Peer Review

Overall well structured and presented page so far.

Key points clearly described: From what I read on your page, the key points appear to have been clearly described. If I was reading about something, that I was not sure of, I could easily find a description or definition elsewhere on your page.

Understanding? Content, headings, sub – headings, diagrams, tables, graphs? Teaching at peer level? Own innovative diagrams, tables or figures, Interesting examples or explanations?: I like how you’ve set out the page, breaking down the information, and explaining it as you go along in a logical sequence. Content and sub – headings are well chosen, and provide a good background to integrins. The diagram under the ‘Integrins’ heading, ‘A simple diagram of … cytoskeleton to the ECM’, helps the reader visual the process. Possibly though, tidy up the diagram (and scan it (I don’t think it’s a ‘scanned’ image) for better quality) by ensuring that the different parts of the diagram are in correspondence with each other, e.g. the plasma membrane is not uniform in shape and size. Furthermore, to maintain professionalism, maybe the labels should all be in capitals (so that it looks neater) or typed. The graph is well chosen. So are the other images on the page and their corresponding labels. However, why were the integrin structure images next to the ‘Function’ section of the page? I found this to be odd – placed. If it was intended to be for ‘Functional Structure’, you should relocate the images accordingly to avoid the confusion. Alternatively (and possibly for the other images as well), have references to the images, within the text, e.g. under ‘general structure’ you have (iii.) referring to the diagram – include ‘see figure 1’, or something similar to make it clearer. Also, I thought the video was a fantastic idea! It really helps visualise the integrin interaction.

Content correctly cited and referenced:The content appeared to be correctly cited. There are random citations and links here and there - I understand it’s still a work in progress; just don’t forget to fix this up!

Evidence of significant research / Adequate research: There appears to be a good deal of research, as when you read through the page, the different elements tie up well together. However, I don’t feel that this research is necessarily ‘adequate’. I feel you need to read a couple more articles and reference them on your page, rather then referencing the same article 2 – 3 times throughout the text. The more articles you use, the more supported and accurate your page will be, and the concepts will be better worded/ explained.

Other: Knowing that the page is still in progress, make sure you go over and correct and spelling, punctuation and grammatical errors (I noticed quite a few). Some of your sentences are too long and wordy – work on sentence structure. Under ‘general function’, the sentence reads ‘two main cellular functions’ – what are they? List them or point them out. You also need to add paragraphs to this same section (gen. function). It’s too clumped and difficult to read when together. I also think you need a paragraph explaining why you’ve listed ‘integrin trafficking, fibronetin, collagen, laminin etc’ under ‘interaction with the extracellular matrix’. Just a sentence saying what role those components play in interaction should be sufficient, so that the viewer knows why they are reading about all those other components and how they fit in with ‘integrins’. Initiation of metastasis and interaction with ECM components and stiffening of the ECM are two very, very long paragraphs. Ensure the paragraph breaks are more obvious and add pictures. When you read scientific papers/ wikis/ articles, you find yourself distracted when you have to read long lengthy paragraphs. In particular if scientific terminology is used that you’re not familiar with – you dread it! If you separate the text into more obvious paragraphs, it will give the reader a break and help them absorb what they read. Glossary is a fantastic idea. Possibly even list any terminology that those who are not in the scientific field, may not understand.

Project 2 Overall, the Integrins wiki is looking quite nice. The biggest thing you need to do going forward is try to eliminate content duplication (ie stuff from one paragraph appearing again later in the page), which will be a matter of checking each other’s work.

There’s a bit of formatting stuff that needs to be cleaned up, also. For example, there’s a random sciencedirect link that I guess is meant to be part of a reference tag at the end of the first section. You also need to decide whether you place the ref tag after the full stop (as in [3]) or before (as in [2]). The timeline in the history section obviously needs some work.

The hand drawn integrins diagram is very well drawn but you really need to scan it rather than taking a photo with a phone. It looks terribly out-of-place as it is at the moment.

Overall, the fact that I need to nit-pick this so much probably means you’re doing a good job so far! Your notes indicate that you know where you need to go next – continue to work hard and you should have a good product at the end!


Group 2 Peer Review

Group 2, the keypoints seem to be well described, as well as the content, headings and subheadings. The association between integrins and other ECM compounds was very creative and gave extra good information. When it comes to the disease topic, I think you guys explored it well, giving good explanation on a more specific way, interrelating cancer subjects with cell biology ones accurately.

The images, graphic and the video feet just perfect, showing on a simple but easy to understand way. However, I think the general structure lacks a bit more of fluidity; you could organize some topics into dot points, for example, and regarding the disease topic, I think some info can be more summarized as it is a very long topic.

Group 2 Peer Review

In general, your project looks very good, congratulations! It has not only good and beautiful images, but also a clear and comprehensive text. The organization and the appearance of the page are also pretty good!

The introduction is very clear, comprehensive and concise, which helps the reader to understand the following parts. The history section, however, seems to lack information, because it only says how the integrins were discovered, but it does not say what happened later. The diagram that shows how integrins relates to other proteins is very good and clear, and it shows that the one who draw it has potential to be an artist.

The structure part is very good, but the text in this section starts with information that should be present in other sections, such as introduction and function. Anyway, this section has a clear and rich text, and the images provided helps a lot in the understanding of the integrin’s structure.

The remaining parts look pretty good, but I think you guys should improve the look of the disease section: maybe putting some images there would be a very good thing to do. And the idea of putting a glossary at the end shows that you guys are interested in creating a clear and understandable project. Cheers!!!

Group 2: Pros: You guys seem to be on top of things. It is evident that you guys know where you want to go with this topic. This is shown through your choice of content, headings, sub-headings, diagrams and graphs. Good job with finding a video for your topic! There is use of the student’s own diagrams. There is adequate information in all subheadings of the topic – which shows you guys have really researched thoroughly. Cons/improvements: Im not sure as a reader where you are going with the section underneath the glossary? The last section is a bit too lengthy as well.


Group 2 peer review

The page is very well organized so far. However, there are some important information about future research that can be added, since interns are very relevant proteins with a lot of functions in the human body.

The structure section is still lacking some contents on synthesis and regulation, however so far the provided information is well-explained and easy to understand. The posted image, combined with the text, allows a clear comprehension on the general structure of the integrins.

Regarding the role of interns in disease, the association between cancer metastasis and the extracellular matrix is something that captures our attention due to cancer's prevalence and incidence. For this reason, I think it would be interesting to add some pictures to this section relating integrins and cancer, providing an even better understanding of this association.

Overall, I believe the page is well-organized so far, but some edit can still be made when regarding future researches, synthesis, regulations and clinical manifestations.


Group 2 peer review

First, key points relating to the Integrins are clearly described. The contents are well-organised because they are divided in relevant sections. The introduction explained what is Integrins is very clearly and briefly and I consider this good for the reader (the only problem is the website link in the final should be placed in reference section).

The History section is not completely done, but I know the page is still in progress. The graphic showing the interest in researching Integrins was a very good idea and gives to the reader an interesting impression about Integrins history and perspectives.

The Structure section is very good and clearly, but I think the introduction in this section was a bit repetitive and very similar with the function. In the Function section, it is not clearly what is the “two functions” cited in the beginning of explanation, but even it is possible to understand the functions. Furthermore, the “interactions with the Extracellular matrix” is a amazing point that you explained.

Finally, the role of integrins in disease is clearly but it would be good if you put some images. The glossary was a very good idea, but I think it is still in progress.

Overall, considering that you are still working on the page, it is a good job so far. I think when you finish the page, including the history section, adding images and completing some sections, it will be very useful for learning about Integrins.

Group 2 Peer Review:

You guys have made great progress so far and overall i would say the majority of your project is complete and only final refinements are needed to make it perfect. The structure of your page is clear and logical and makes for an enjoyable reading experience. I really enjoyed the tome of your writing as all your concepts were well explained in language that was easy to follow and understand. The information was good as was the use of images and videos - a really interesting touch.

From a formatting point of view, you have made really good decisions. As a recommendation though, I would consider adding a heading and image before the contents of your page. I feel this would give the reader an immediate context to your topic and page and grab their attention. Also Your introduction read as though it was unfinished. I'm not sure if this is the case but if you intend to end it as is, it would probably be best to round it off better.

The hand-drawn image that included looks great but the lighting of the photograph isn't great so I would re-take the photo in a better lit environment to make sure its clear to see and read. Also if theres time, adding some colour would be good.

Another suggestion id make is to reconsider your discovery section and the timeline that follows later on. Having both separated is a bit redundant and id rather see them side by side so the timeline is more of a visual aid for the discovery section. Or you could just transfer the information from paragraphs into a more detailed timeline. either way i just think having both in their current positions is unnecessary.

I hope this feedback is helpful. All the best & good luck!


GROUP 2 PEER REVIEW

The organisation of the page is well thought out and there is very good use of subheadings to break up information which makes it much easier to read. The introduction and function sections have been written concisely and organised well. For the history section try to separate different events into dates as a timeline, rather than having a large paragraph. Structure is also well written despite being incomplete. Good use of subheadings but it lacks referencing in this section. The disease section is extremely detailed with large blocks of information. Try to be more concise and break the information up into different paragraphs.

Good inclusion of a video about the interaction of integrins with the extracellular matrix in the function section. There are few relevant images of integrins and interactions with the extracellular matrix. The diagrams, videos and images help in the understanding of the information.

There appears to be some problems with the referencing. References 19-21 do not appear, which is due to some coding error. Otherwise, the other sources appear correctly referenced. Although the page is still a work in progress, the page is really well set out. The function section has been really well done and I believe the layout for this section should be used as an example for other sections.


You have a brief and concise introduction, which is good. Just don’t forget to mention everything that will be included in your page when you start doing the final touches of your page. I can see that your history section is still in the works. It’s a good start. My suggestion is to add in what CSAT and JG-22 stands for because it can be quite confusing (I had to read it a few times to understand.) It’s good that you plan to include future research and a timeline. Regarding the timeline, do it if you have enough dates and events to include, which you can turn into a visual timeline and I think that would really impress everyone.

As for structure, although not complete, It is well-written and understandable. There is a bit of overlap with function but that’s alright. The photo included really helped visualise and understand the structure of your topic. My only issue with this section is the amount of references included. So far, I can only see one. Try to use four to five more papers just to make sure that your information is consistent with other papers.

For function, great job! I really like this section and to whoever did this section, you should be proud. It’s well-written and straight to the point. I like how you linked the function of integrin with the other extracellular matrix components. I think it welds all the group projects together. Also, smart move on including a video. A few problems with this section though is the lack of connection with the photos (and video) and the text. If you could add a brief description about what is happening in the video, that would really be great! There is a good amount of references used in this section.

For abnormalities, very interesting section especially with the cancer part of it. It is nicely written and understandable considering the amount of information I know about integrins. Try to add in a few photos to aid the text. Also, “ tumour initiating cells, or TICs,” you don’t have to say “or TICs” just add in (TICs) right after tumour initiating cells. I can see that you’ve done it with the other terms so just try to keep consistency with your writing. Overall, it’s a good section and I would say it is a very good effort considering that integrins, as you have mentioned, does not have that many evidence relating to diseases yet.

Regarding your photos, I like that you included text to describe what the photo is about. Don’t forget to include a student copyright in your student-drawn image. “Copyright Beginning six months after publication, I (student number) grant the public the non-exclusive right to copy, distribute, or display the Work under a Creative Commons Attribution-Noncommercial-Share Alike 3.0 Unported license, as described at http://creativecommons.org/licenses/by-nc-sa/3.0/ and http://creativecommons.org/licenses/by-nc-sa/3.0/legalcode” Speaking of copyright, you have two images that are protected by copyright and you can’t use them. This one Integrin_Structure_and_Function_schematic.jpg and Integrin_structure_and_components.jpg. Lastly, with referencing, I can see that you have repeating references. Try to fix this by using the format given in the Lab 1 Handout - One page Wiki Reference Card


Group 2:

You guys are doing a really great job with your project! The layout looks really good. There is a great amount of information as well as several images to accompany this text. In particular, the animation really adds to the page and assists in the reader's understanding of the concepts covered. With this being said, there are still sub-headings that require information to be added to them. Also, there are minor grammatical errors that need to be corrected.

It’s great to see that you guys have also implemented your own illustration. However, I suggest maybe adjusting the contrast to increase the quality of the image. Also, you guys have made a good start to the history section but there are still sub-headings that need to be added to it. Similarly, there are sections in the reference list that are blank, and while the glossary is looking good, there are still terms that require defining. Lastly, ensure you guys do not forget to remove all your notes and reminders to each other from the project page before submission. Also, don’t forget to address the issues that Mark has raised on the page.

Good set of images, those 3D perceptions are useful to clarify the structure. Smart initiative add one video to the project, the more interactive the more people pay attention. Maybe formatting the text of the project would be nice, more spaces between big texts and some images in the "disease" section, the texts and images are condensed maybe spread them and create a balance. I would edit the first image too, the draw is perfect but maybe some bright and contrast to make it more evident. The page is very informative and practical, congratulations!

Group 2 Peer Review

The integrins introduction is very well done. The key points are clear, it’s very straight forward and comprehensive. The association with the ECM here is a good start to your page.

The hand drawn image of integrin interaction with cytoskeleton is well drawn – however, I think you should scan the image for a better quality finish and also place this image in your structure/function section where it can be referred to there. Being in your introduction section with little to no reference to it, makes it appear less essential to your project.

The History section has enough information to give us an insight to the years of research that went into integrin discovery. Once the Future Research section is complete I think this section of your wiki will be very informative.

Good start to the structure component of your wiki – the image ‘Integrin Structure and Function schematic’ is well referred to in the paragraph to its left. Consider labeling the image or drawing your own or attaching a legend to the image because at this stage there’s no telling what is what in the image, eg. MIDAS, ligands, etc.

The images that are for structure should be in your structure section, not with the functional paragraphs. The video is a great addition to the wiki and also the linkage between ECM and integrins.

The disease section is very extensive and it’s clear that you have done a lot of research in this area. It could be further aided by the addition of a few images.

Your sub-headings show you have a good understanding of what your topic is about, and what your wiki needs in order to inform your readers about topic. There are some grammatical errors so be sure to go back and fix them up as well as the links that are just ‘lying around!’

Group 2 Peer Review

I think the layout of the page is done well, with all your constituent topics and subtopics. Although I think you need a lot more information in some of the subtopics especially in structure and function and a little on diseases. Based on your reference list it seems that you've done quite a bit of research, you just need to try to add more content and maybe more detail. Your in-text citations are formatted really well, but I think you don't know how to reference the websites so here are some tips. Go to the tab on the left hand side of the main page and click on editing basics, there should be a tab on project referencing. If your referencing a website add these symbols without the brackets [1]. I also noticed on your reference list you have some references that show up on the list and there's an empty space, maybe look over your formula again or refer to the project referencing tab. I like your use of images they are nice and vibrant, good use of a table in the future research topic. Also you've provided a great variety of different formats to show the function and structure of intergrins. This is really great !! I like that you've used a video its wonderful as sometimes content can be difficult and boring to understand. Thus this video is short, clear and a good way to show the interaction with the extracellular matrix. I'd suggest adding more images to the diseases component of the page, if you have trouble finding some that can be reproduced then maybe draw them yourselves. I think it's great that you've provided a glossary of terms, that's very useful but again I think there must be a formatting issue as there are strange boxes under the table. Also add an introduction to your page, to cover a basic overview of what will be contained within the project page and a summary of intergrins. In summary I think you've done some good work on the page, but some content still needs to have more info and detail. Once that is complete the page will be really great.

Keep up the good work and good luck :).


Group 2 Peer review

Introduction text is good, but doesn't do a very good job in drawing in the reader's attention. Some formatting should fix that up. Discovery (history) section is very informative, but maybe try to add the images that you refer to in that section. Future/Current Research obviously needs to have something added. I would say that the interest in integrins section is redundant and doesn't need to be there. Consider removing or placing that section in a dropdown/link as it doesn't really add anything to the page. make sure to review what you have on the page before submitting work. don't want parts like the NOTES comment or in the intro to Structure. Structure information looks good, but there is very little citations, none, in some areas. make sure to cite everything guys. Some formatting work and in text review is in order, but the page is on the right track.


Group 2

Having a quick initial look through your project, there seems to be a lot of quality and in-depth information under their respective correct subheadings. The structure section was described in a simple yet very descriptive way allowing me to understand the basic outline of what an Integrin consisted of. There are some parts of this section which is still under construction, nevertheless it is still well written. The function section provides some nice base information with a nice video (there is no sound?) however the video seems rather fast and I had to re-watch it a few times, maybe slowing it down if possible would be great but other than that, the images were great and correctly cited. It was great to see how you talked about Integrin and its interaction with other molecules around it and how it went about in their interactions.

The Disease section is very informative, but it is very hard to read the wall of text. Maybe incorporate images related to the diseases in between the text would be better in breaking up the information, but other than that, you did provide clear concise information on the role of each Integrin in the disease so well done!

In terms of improvement, I think more information on History and Timeline can be provided as well as some information on the synthesis and regulation section of your project. The project is coming together nicely! Well done!

Group 2: Integrins

Your introduction is a nice way to welcome people to your page and will tie in well with your history section when more information is added to that part of your page. The timeline and future research sections will be a great addition and will make your page seem more relevant. You could talk about important discoveries and medical applications of future research.

So far your structure section is well written although it is clear that it still needs work. The image in the really works well with the text and makes the concepts easy to understand. This section definitely needs more references to support your text.

No think the function section is the best part of your page so far. It is concise and really well written. You linked to other EM components and i think this is an opportunity for you to use links to the pages of other groups to make your page more interactive. My only issues with this page are surrounding he images and video. They seem to be just placed in amongst the text and although they are interesting they look out of place without some sort of reference to them in your text. Perhaps you could include a brief overview of the video underneath it or within your text.

The abnormalities section could be really improved by including more images but it is still a well written and informative section. You should be really proud of this effort so far because you must have really worked hard to find information pertaining to integrins. Well done.

People have mentioned problems with your referencing for you images so I won't harp on about that but I really like how you have included text to describe the images. I noticed that some of your abbreviations have no explanation so perhaps you could include a small table at bottom of your page to explain them (e.g for CSAT and JG-22). It is clear you have used a variety of references to source your work and someone has already mentioned how to fix he problem with repeating references in your formatting. Good work, your page will be an excellent resource when you fix all the issues and develop the sections that are lacking.


Group 2

The Integrin introduction appears to be unfinished, however the subheadings and text indicates an adequate amount of research on this topic. The timeline is a good teaching skill which sets out the history is an effective manner. The picture used is a little dark. Consider using pen or color in pictures. In section of structure the information is detailed going beyond basic science while relating back to the cell biology aims. More work needs to be done under the headings specialty, function structure and synthesis and regulation. The section on function has been done very well. The content effectively demonstrates an adequate amount of research on this topic and is very informative. The subheadings, diagrams and videos are very effective in aiding teaching and add to the section as a whole. The section on disease has also been done very well. The information is detailed going beyond basic science while relating back to the cell biology aims. Consider including a picture to aid the teaching element. The glossary at the bottom of the page is a very effective tool to aid the reader and the color makes the page more interesting.

Overall this group project was done very well. The choices of headings used are quite good, covering the key areas necessary to inform learning and indicating a good understanding of the topic. The subheadings indicate a good understanding of the topic. The content effectively demonstrates an adequate amount of research on this topic and is very informative. Furthermore the information is quite detailed going beyond basic science while relating back to the cell biology aims. Overall a wide variety of pictures have been used adding an element of teaching. The Content is correctly cited with in text citation used throughout the wiki page. The references are also done correctly except for a few missing references at the bottom (17, 19, 20 and 21). A lot of work still needs to be done but the basis of this report is very good.


Group 2

Great work, it looks like your group has a clear mindset and direction to where your group project is going, even if it is not completely finished yet. It is clear that an extensive amount of work has been made by this group and is reflected in amount of information/content. There are a good number of images already on you group project page, however, under the headings for the role of integrin and function of integrin there is not as many images. Perhaps try including more images that will balance the text with the visual information. Well done for already including a hand drawn image on your page.

There also appears to a number of links that have been inserted randomly. You probably want those there as they are relevant to the subsequent headings just don't forget to take them out or include them in your reference list as most of them are from PubMed anyway, so just copy the ID number.

There appears to be some comments from other group members on the group project page, whilst I understand that this is still a work in progress, just don't forget to remove these things before final submission and also make sure you have the copy right allowance to reuse their images.
