The gene’s abbreviation is FTO because a deletion in a homologous region in mice results in fused toes (FT) and other abnormalities.[2] The gene name “Fatso” was given in 1999, before its association with obesity was known. The function of FTO is unknown. The study that found the gene, and the only study that experimentally looked at its function, is probably unsuitable for inferring the functional role because the deleted region involved five other genes.

SCI论文全攻略(转自星莹论坛)
第一部分:选题与创新
一、先想先写最后做:
1. 做研究之前,必须想清楚:结果能不能发表?发表在哪里?
2. 先把文章大框写好,空出数据,等做完实验填完空就可以发了;正所谓心中有沟壑!
3. 在未搞清“写什么、发哪里、自己研究与同类研究有何出色之处”之前,就不要动手做!
4. 继续去看文献,去想;想不清楚就做还不如不做!
5. 要想这样做,就得先看文献!要知道如何把文章架起来、要知道别人是如何讨论的、要知道自己的数据是不是说明了与别人不同的东东或别人没有做过……这个过程就是阅读文献及思考的过程,这些搞清楚了,写就简单了!
6. 要是先做事,做完发现别人做过,或无法用理论来解释,岂不是冤大头?

在国外很多大学把自己的学位论文公布于网上,即electronic theses and dissertations (ETDs)项目,但是一般的搜索引擎难于发现,OAIster可以寻找到这些好东西:)
