Importance of Dephosphorylation in Molecular Biology
In biochemistry and molecular biology, reversible covalent modification by phosphatases and kinases is central to regulation of enzyme activity and gene expression. The enzyme phosphatase works by removing a phosphate group through the hydrolytic process of dephosphorylation. And, while other reversible covalent protein modifications exist (acetylation-deacetylation, adenylylation-deadenylylation, uridylylation-deuridylylation, and methyl­ation-demethylation), the phosphorylation-dephosphorylation pair is the only one that catalyzes and synthesizes high-energy molecules for use elsewhere in the cell. Dephosphorylation is necessary for the proper function of most molecular switches and enzymes. Thus, the process of dephosphorylation is arguably the most important mechanism in molecular biology.

State of the Current Dephosphorylation Article
The dephosphorylation article is currently classified as a stub within the biochemistry category. The article provides a very brief (three sentence) explanation of dephosphorylation, but none of the information is linked to citations or references. Additionally, there is no activity on the talk page, indicating that there has not been productive interaction of Wikipedia editors prior to our group taking on the goal of improving the dephosphorylation page. To improve the quality of this article to good article status, we will need to expand the broadness of information provided about dephosphorylation, provide ample citations for that information, and add suitable images that add to the overall usefulness of the article.

Pubmed Citation Practice
With cancer treatments such as chemotherapy becoming more successful and leading to longer life expectancy for cancer patients, quality of post-cancer life, not just survival, must be considered in how therapy is pursued. By looking at variations in hormones relating to the ability to conceive, researchers have found that ovarian stimulation is modified in women undergoing ganadotoxic therapy.

Similarly, ovarian reserve before and after chemotherapy has also been looked at. The variation in a women's reserve as a function of chemotherapy treatment is tied to the levels of AMH, a hormone which must be of a certain level for ovulation to occur. As such, AMH levels are determined before starting ganadotoxic therapy.

Pillars of Wikipedia
A summary of the five pillars of Wikipedia

1. Wikipedia is an encyclopedia

Information is organized in wikipedia as a central repository, and wikipedia is not the place to interpret this information or share opinions.

2. Wikipedia is written from a neutral point of view

Articles should reflect established fact without bias which favors one view over the other.

3. Wikipedia is free content that anyone can edit, use, modify, and distribute

Copyrighted material should not be used on Wikipedia without permission. In turn, information on Wikipedia may be freely used by anyone.

4. Editors should interact with each other in a respectful and civil manner

Editors are to work together to find consensus, not to argue and resort to personal attacks.

5. Wikipedia does not have firm rules

Wikipedia is designed to grow and adapt. Therefore, the rules are more of guidelines than end all decrees.

Summary of characteristics of target article
Wikipedia articles are considered to be of "B" quality when the article is for the most part complete and does not have technical issues, but is still missing components that make a good article. "GA" articles improve on the "B" rating, as GA articles approach the quality of a professional, objective encyclopedia. However, GA status articles can still be improved. Often these articles still require some style and content editing by experts, and efforts are needed to better integrate the article with other articles on Wikipedia.
