Manik and Sophie, I cut and pasted your reference list into the Bibliography page, remember to use that page rather than the Talk page for references.
Sophie, You don't have to sign after each entry, you can enter several ref then sign at the end of your list. It's a nice selection, good start. Nancy Sabatier 17:00, 5 October 2010 (UTC)
Sophie, Manik, the article looks good so far! I think it was a good idea to select one of the most important genes in the control of food intake rather than trying to write about npy, leptin, ghrelin and all the other, seemingly endless, gene products that are involved. The article outline is good, how is the fleshing-out coming on? John Menzies 11:20, 27 October 2010 (UTC)
Related articles
You'll see that on the Related articles subpage I've placed links to all the articles from the other groups this year - and also to last year's articles. Good luck with this.Gareth Leng 15:58, 9 October 2010 (UTC)

Some very impressive work on this article. Some specific minor concerns
"Ghrelin was shown using fluorescent protein tagged NPY neurons, to increase release of NPY and AgRP" No, need to check on exactly what was done.
