研究稱發(fā)現(xiàn)部分人肥胖是由于基因突變所致

    食品伙伴網(wǎng)訊  據(jù)外媒報道，近日《臨床研究雜志》刊登一項研究表明，有些肥胖癥不是吃太多或不運(yùn)動而造成的，真正原因是基因。

    突變基因控制傳送給大腦特定區(qū)塊的信息，這部分的大腦區(qū)塊負(fù)責(zé)控制食欲和決定燃燒脂肪的多少。專家認(rèn)為，確認(rèn)這個基因?qū)θ梭w造成的效應(yīng)，能更快開發(fā)抵抗肥胖癥的藥物治療。

    Two studies zero in on DNA-based drivers of weight. Is obesity written in our genes?

    In two separate papers, published in the journal Science and in the Journal of Clinical Investigation （JCI）， researchers describe new genetic factors that could explain weight gain in some people. In the Science study, researchers at Boston Children's Hospital studying mice found a rare genetic mutation that prevented the animals from burning off fat calories. They also found the same gene was mutated in a group of obese people. And a team based at University College London reported in JCI that a specific form of a gene previously linked to obesity, FTO, can increase craving for high-fat foods.
