Gene Variation Linked to Waist Size
Gene Variation Linked to Waist Size
<p>
<p>Some people may be able to blame their beer bellies at least partially on genes, a new study out of Sweden suggests.</p>
<p> Researchers found that a particular variant in a gene linked to fat metabolism may help fight flab around the middle. In their study of middle-aged men, those
without the variant had wider waistlines, on average.</p>
<p> The gene governs a protein called apolipoprotein A-II (apo A-II), a component of HDL (“good”) cholesterol. Research in mice has suggested that, among other
metabolism-related jobs, apo A-II may help control body fat accumulation. But its role in the human body is not fully understood.</p>
<p> To dig deeper, Dr. Ferdinand M. van 't Hooft and colleagues at the Karolinska Institute in Stockholm analyzed the apo A-II gene in 624 healthy 50-year-old men. The
investigators found that men with a variant dubbed 265C were leaner in the middle and showed greater metabolism of certain blood fats. 大肚腩也是基因问题
一项瑞典的科学研究称，某些人的“啤酒肚”可能与基因有一定联系。</p>
<p> 科学家发现，一种与脂肪代谢有关的基因特殊变体能够帮助人们对抗“中年发福”的现象。平均来说，那些缺少这种基因变体的中年男子就会有啤酒肚。</p>
<p> 这种基因主要控制一种名叫阿朴脂蛋白A-Ⅱ的蛋白质，而这种蛋白质在人体中的作用并不十分清楚，科学家表示它可能可以帮助人体控制的脂肪积累。</p>
<p> 为了深入研究这一问题，科学家对624名健康的50岁男子体内的阿朴脂蛋白A-Ⅱ基因进行了研究，结果发现凡是这种基因内拥有一种叫做265C的变体的男子都比较瘦，对某些血脂的代谢能力也较强。</p>
