Super Resolution Microscopy 
Super resolution microscopy is an important investigative instrument used by many scientists to gain a higher resolution. The research article 'Super-Resolution Microscopy Reveals Specific Recruitment of HIV-1 Envelope Proteins to Viral Assembly Sites Dependent on the Envelope C-Terminal Tail'investigates the mechanism of Envelope Glycoprotein recruitment and virus incorporation of human immunodeficency(HIV-1). Super resolution microscopy was used to visualise the Gag assemnly sites and Envelope Glycoproteins in infected, virus producing cells. Dual-Colour Super-resolution microscopy allowed the scientists to bypass the resolutions provided by Fluorescence microscopy and Confocal microscopy by allowing the researchers to obtain a reoslution that is near molecular level. By using the super resolution microscopy to look at distribution patterns of Gag and Envelope proteins the research article concludes that Envelope proteins have a larger role in mediating the viral infection. Technology of this magnitude allows us to almost investigate to a near molcular level of mechanisms in the body.
--Mark Hill (talk) 10:15, 11 April 2013 (EST) References are formatted correctly. The research article is both recent and uses stochastic super-resolution microscopy in its findings (as well as combined PALM and dSTORM). You have explained how this is relevant.
Transient nuclear envelope rupturing during interphase in human cancer cells 
The research article ‘Transient nuclear envelope rupturing during interphase in human cancer cells’ explores the rupturing of the nuclear envelope in cancer cells using various techniques such as cell culture, siRNA transfection as well as live and confocal imaging and the use of the electron microscope. Cancer cells can be diagnosed by the presence of nuclear envelope invaginations and extrusions. However despite this clinical pattern it is unclear why changes in structure of the nuclear envelope is present in cancer cells. The findings of the paper illustrate that the nuclear lamina, intermediate filaments that provide support to the nuclear envelope, was not properly formed in cancer cells that had ruptured nuclear envelopes. Furthermore it was found that nuclear envelope rupture occurred when there was an entrapment of cytoplasmic in the nuclear interior. This research article is relevant to the sub-topic of 'nuclear envelope at the onset of mitosis' as it looks at the rupturing of the nuclear envelope during interphase in cancer cells furthermore it can also be used for the sub topic 'current research'. As there is a clinical correlation between abnormal nuclear envelope and cancer cells it is important to gain an understanding into the causation of this relationship.
Mislocalization of nuclear and cytoplasmic components
The SUN Protein Mps3 Is Required for Spindle Pole Body Insertion into the Nuclear Membrane and Nuclear Envelope Homeostasis 
The article 'The SUN Protein Mps3 Is Required for Spindle Pole Body Insertion into the Nuclear Membrane and Nuclear Envelope Homeostasis' explores the mechanism of spindle pole body (SPB) into the nuclear membrane in budding yeast cells. The research paper states that the action of integral membrane proteins facilitate changes in the nuclear envelope. The investigators looked at an SPB component called Mps3. By observing a mutant of Mps3 known as MPS3-G186K through the means of an electron microscope it was revealed that Mps3 directly affects lipid homeostasis. As the nuclear envelope is composed of lipids the paper suggested that Mps3 mediates the insertion of SPBs in the nuclear membrane. Previous studies suggested that Mps3 was involved in the intiation of SPB duplication however this study broadens this concept by revealing that it is responsible for membrance homeostasis which constitutes insertion of SPB into the nuclear envelope. This study is important in not only understanding the the nuclear envelope during spindle formation but also reveals a certain direction current ressearch is heading. Hence it is useful for the subheading 'current research'.
Formation of the postmitotic nuclear envelope from extended ER cisternae precedes nuclear pore assembly 
The article by Lei Lu and peers deal with formation of the postmitotic nuclear envelope. The study mentions two models, the insertion model and the prepore model. The insertion model suggests that the nuclear pore complexes are embedded in the nuclear envelope after the formation while the prepore model suggests that the nuclear pore complexes aggregate on the chromatin as nucleoporins before the nuclear envelope formation. Through the use of techniques and intruments such as Live-cell imaging and electron microscope tomography the study concludes that the assembly of the nuclear envelope originates from ER cisternae. The study furthermore supports the insetion model to a degree as it concludes that nuclear pore complexes accumulate on the already formed nuclear envelope. This article is relevant to the sub-topic of 'current research' as it looks at the origination of nuclear envelope reformation it can also be used for the sub topic 'reformation of the nuclear envelope'. Overall while this article does not offer significant information to our project it still provides relevant information.
Nuclear envelope structural defects cause chromosomal numerical instability and aneuploidy in ovarian cancer 
The study 'Nuclear envelope structural defects cause chromosomal numerical instability and aneuploidy in ovarian cancer' explores the expression of nuclear envelope proteins lamin A/C in ovarian cancer. The investigation uses teachniques such as siRNA and immunofluorescence microscopy to look at nuclear morphology in conjuction with flow cytometry to inveatigate cellular DNA content. The study found that the proteins lamin A/C are absent in 47% of ovarian cancer cells which indicates that there may be an underlying relationship between the absence of these proteins and the occurance of ovarian cancer. The study concludes that the loss of protiens lamin A/C may lead to a morphological change in the nuclear envelope this then leads to the diagnostic characteristic of cancer. This article is relevant for the sub-topic of 'current research' as it looks at the nuclear envelope in cancer cells which is a future and current topic that is being investigated.

In class assessment on knock-out techniques
1) Do you see any change in phenotypes between group A and group B?
By stuudying the graph above a difference in the morphological phenotype between Group A(Over-expression of Tm4) and Group B(Control) of Neuro-epithelial cells can be observed. Group A, which constituted the cells that overexpressed Tm4 had a significantly higher percentage(42%) of the morphological phenotype D(Pronged)compared to Group B. Furthermore Group B cells had a significantly higher percentage(29%)of the morphological phenotype B (Broken Fan) compared to Group A.
2) If you see a difference, speculate about a potential molecular mechanism that has lead to the change
Tropomysin is an important structural protein found in muscle cells. It has over 40 isoforms which have functions that are relevant to their structure. Tm4 is an isoform that can be found in non muscle cells that are motile such as Neuro-epithelial cells; it facilitates motility. As Tm4 promotes branching and neurite growth it can be established that cells that are overexpressing Tm4 would constitute a higher percentage of morphological phenotypes such as pronged, stumped and stringed. This is consistent with the results above as Group A cells had higher percentages of the phenotype pronged and stumped than the phenotypes fan and broken fan. This trend can be observed as branching and neurite formation is apparent in phenotypes such as pronged, stumped and stringed as opposed phenotypes such as fan and broken fan. While Group A cells exhibited fan and broken fan phenotypes it can be observed that a high percentage of Group A cells exhibited the pronged phenotype. This could be due to Tm4 having a function that deals with the length of neurite formation and the degree of branching in neuro-epithelial cells. As the classification of the cells into the certain phenotypes is somewhat subjective it is best to compare and contrast data from other individuals and groups to make a conclusive statement.

Current and Limitations of Models
- Excellent section as it reads well once again and referenced well.
- The last paragraph of the current model section needs some referencing though.
- An image showing either of the models in the limitations would be good.
Current and Future Research
- There is no specific current research papers.
- The first point needs to be elaborated on.
- Link or reference the actual papers you got this information from to support your text.
Overall This project is researched well and the information put up is relevant. Small things like the glossary and certain points need to be fixed up but overall the project reads well and only minor amendments need to be made.
- Introduction is very brief but excellent. Maybe you can add some references.
- Image is uploaded properly with the appropriate information.
- The timeline is brief and maybe more poitns are needed but the ones listed are relevant and referenced well.
- There are too many colours however, maybe stick with a pattern like the other tables used in projects.
- Good use of the sub headings to break up the information. The information itself is excellent and well readable and it helps that you have linked the terms to the glosaary.

Overall This project is researched very well and there is little to change and add. It reads well and informs well. Futhermore the use of external links is excellent as some other projects lack this part.
Group 1-Regulation of Cell Division
- As this topic is specific to cell division more than the others i think its safe to say that you could incorporate a brief overview of the cell cycle.
- An image here would also be very helpful. Maybe an image of the cell cycle that you made/drew yourself.
- The use of the video is excellent however its not up yet.
- History is incomplete and needs to be completed after 1992.
- Each date is referenced and is relevant to what is discussed.
- The light green colour is sufficient to read the information.
Entry into the M phase
- This part lacks some references.
- Futhermore you need to explain what M phase and the G2 phase is. You can either do this in the Introduction part or in this part. I see you have put up a small image of the cycle however you havnt explained the basic activities that happens in the cycle eg the M cycle is the mitotic part.
- The information on the CDKs and Cylins is good as it covers what they are however you have put in history of the Cyclins in this part and i feel maybe the history should be posted in the history sub heading.
- The student image uploaded isnt referenced properly. You need to description of the image (roughly a paragraph), copyright information, student image information etc.
- I see you have referenced and copyrighted the image of the cycle however you might want to make it a thumb so theres information under it.
Metaphase to Anaphase Transition
- Why is there text in the brackets? You might want to talk about what was done in that study and write a paragraph on it.
- Information is to the point however i feel like its lacking (how is the spindle check point activated?)
Mitogens and Cell Division
- Im sorry i dont understand Entry into Start? (Start of what).
- The paragraphs about Mitogens is very succinct and flows very well.
- The PDGF paragraph is also very well written and the image used is relevant to the information presented.
- There are points at the end of this section that should be elaborated on.
- Table format is excellent however it restricts the amount of information you can give. If you dont want to give a lot of information on the disease then the table is perfect.
- The table needs to be completed
Current and Future Research
- Good starting point however maybe have some specific references to the current and future research.
- Number 20 has nothing there.
Overall This project is written well and certain parts just need to be completed. Just fix up certain things such as referencing and uploading the images properly and adding more images. Also add some more references if possible.
