Revision as of 15:08, 28 March 2017
Welcome to Cell Biology 2017!
- Identify a chemical SDS and the risks and hazards of that chemical in text. Add a link to the original SDS
- Select 4 reference papers papers related to your selected group project topic sub-section. Read the research papers and write a brief description of their findings and relevance to the selected topic sub-section. The reference along with your description should then be pasted on both your group discussion page and your own personal page.
Lab 3 Assessment - Endo/Exo worksheet questions.
Lab 4 Assessment
- Identify a cytoskeletal antibody.
- Identify the species deriving the antibody.
- Identify the working concentration for the antibody.
- Identify a secondary antibody that could be used with this antibody.
- Identify a paper that has used this antibody.
This assessment will be due by the next lab (Lab 5).
Lab 7 Assessment
The following peer assessment exercise should be completed before next lab (Lab 8 - 2 May) as your individual assessment for this week (lab missed due to public holiday).
Your answer should be pasted in 2 places
- onto each project discussion page (Note you should add anonymously to the discussion page)
- your own individual student page for my assessment.
Each individual will provide a brief assessment of the other groups projects. This should take the form of a brief critical (balanced) assessment identifying both the positive (good) and negative (bad) aspects of the project page as it currently exists online.
You may if you choose, use the final project assessment criteria as a guide. Though you are also welcome to use your own criteria.
Group Assessment Criteria
- The key points relating to the topic that your group allocated are clearly described.
- The choice of content, headings and sub-headings, diagrams, tables, graphs show a good understanding of the topic area.
- Content is correctly cited and referenced.
- The wiki has an element of teaching at a peer level using the student's own innovative diagrams, tables or figures and/or using interesting examples or explanations.
- Evidence of significant research relating to basic and applied sciences that goes beyond the formal teaching activities.
- Relates the topic and content of the Wiki entry to learning aims of cell biology.
- Clearly reflects on editing/feedback from group peers and articulates how the Wiki could be improved (or not) based on peer comments/feedback. Demonstrates an ability to review own work when criticised in an open edited wiki format. Reflects on what was learned from the process of editing a peer's wiki.
- Evaluates own performance and that of group peers to give a rounded summary of this wiki process in terms of group effort and achievement.
- The content of the wiki should demonstrate to the reader that your group has researched adequately on this topic and covered the key areas necessary to inform your peers in their learning.
- Develops and edits the wiki entries in accordance with the above guidelines.

Article Title: Resveratrol and curcumin enhance pancreatic β-cell function by inhibiting phosphodiesterase activity
Article Description: The key aim of this study is to determine the relationship between pancreatic β-cell function, resveratrol (RES) and curcumin (CUR), to examine whether or not RES and CUR enhances pancreatic β-cell function. RES and CUR are polyphenols, found predominately within fruits and turmeric, which have been previously reported to contain medicinal properties that are beneficial to diabetes mellitus patients. Previously published studies claim that the therapeutic properties of RES and CUR can be attributed to their anti-inflammatory effects and protection against β-cell dysfunction. This study thus seeks to examine such reported phenomenon by examining the mechanism/s of action of RES and CUR in β-cells. Results indicate that RES and CUR regulate insulin secretion under glucose-stimulated conditions, and increase intracellular levels of cAMP, which plays an important role in insulin secretion and pancreatic β-cell health. The study also showcases that RES and CUR inhibit the activity of phosphodiesterases, which degrade cAMP. The polyphenols RES and CUR thus indeed enhance pancreatic β-cell function and have therapeutic benefits to diabetic patients.

Article Title: Ultrastructural Alterations of Pancreatic Beta Cells in Human Diabetes Mellitus
Article Description: The aim of this article is to investigate the correlation between pancreatic beta cells and diabetes mellitus, within humans. This is done by focusing on the ultrastructural alterations of beta cells in human diabetes. Throughout the study, beta cells have been retrieved from the pancreas of eight non-diabetic, five type 1 diabetic and eight type 2 diabetic organ donors, and analysed under morphometric electron microscopy. Results have indicated that lower quantities of beta cells are present in patients suffering type 1 and 2 diabetes, compared to non-diabetic patients. Additionally, insulin granules are more represented in non-diabetic patients than in type 2 diabetic patients, while type 1 diabetic patients show minimal changes. Pancreatic beta cells within diabetic patients have also showcased greater apoptosis than beta cells in non-diabetics. These results are expected to improve therapeutic measures for diabetes.

Article Title: Impairment of pancreatic β-cell function by chronic intermittent hypoxia
Article Description: The central purpose of this study is to demonstrate the link between chronic intermittent hypoxia (CIH) and pancreatic β-cell function. Via experimentation on rodents, the results of this study indicate that mitochondrial oxidative stress, which is produced by CIH, causes decreased pancreatic β-cell function, or increased pancreatic β-cell dysfunction. This is demonstrated by augmented basal insulin secretion, insulin resistance, defective proinsulin processing and impaired glucose-stimulated insulin secretion. This study thus contains direct evidence that CIH impacts β-cell function. As CIH is a hallmark of sleep apnoea, this study also indicates that CIH-impacted β-cell dysfunction could be a possible contributor to type 2 diabetes within sleep apnoea patients. It thus encourages possible future research in this area.

Article Title: Protein tyrosine phosphatase-1B modulates pancreatic β-cell mass
Article Description: The goal of this study is to analyse the action/s of protein tyrosine phosphatase 1B (PTP1B), which is an endoplasmic reticulum bound phosphatase that has been previously documented to negatively regulate insulin signalling, in pancreatic islets. Through experimental procedures on rodents and morphometric analysis of their pancreatic cells, the results of this study indicate that mice with PTP1B exhibit increased β-cell area, higher β-cell proliferation and decreased β-cell apoptosis, compared to their wild-type counterparts. This study thus sheds light on the involvement of PTP1B in β-cell physiology, and encourages the potential of PTP1B as a therapeutical target for the treatment of β-cell failure, which is characteristic of type 2 diabetes.
