Nat Commun:肥胖真的与基因密切有关

2015-08-13 MedSci 译 MedSci原创

肥胖仍然是一个全球关注的的健康问题,在美国尤其如此。今年早些时候,Medical News Today报道了美国民众肥胖率的增长情况,预计美国人有超过三分之二为超重或肥胖体质。根据CDC的统计表明,每年用于治疗肥胖的医疗费用约为147-210亿美元。导致肥胖的原因有多种,大家普遍认为相比后天饮食情况及环境,先天遗传的人更有可能肥胖。通过对所有可能导致机体肥胖的基因进行研究,研究人员终于可以确定遗传

肥胖仍然是一个全球关注的的健康问题,在美国尤其如此。今年早些时候,Medical News Today报道了美国民众肥胖率的增长情况,预计美国人有超过三分之二为超重或肥胖体质。根据CDC的统计表明,每年用于治疗肥胖的医疗费用约为147-210亿美元。


导致肥胖的原因有多种,大家普遍认为相比后天饮食情况及环境,先天遗传的人更有可能肥胖。通过对所有可能导致机体肥胖的基因进行研究,研究人员终于可以确定遗传因素在机体肥胖中的作用十分强大。

许多科学家联合开展研究,他们发现,人类基因组中超过100个片段会影响机体是否发展为肥胖体质,例如通过调节机体饥饿感及体内脂肪的分布使机体较易肥胖。

哥伦比亚大学(UBC)的研究人员开始着手探究14-3-3蛋白,它是所有肥胖患者体内脂肪组织的共同组成成分。14-3-3蛋白是高度保守的、所有真核生物细胞中都普遍存在的、在大多数生物物种中由一个基因家族编码的一类蛋白调控家族.它几乎参与生命体所有的生理反应过程。科学家发现当这种基因没有在小鼠体内表达时,小鼠体内白色脂肪会比表达该基因的小鼠少很多。
白色脂肪组织广泛分布在体内皮下组织和内脏周围,主要功能是将体内过剩的能量以中性脂肪的形式储存起来,以供机体在需要的时候使用,是体内脂肪的主要储存形式。机体白色脂肪含量较高时会引发肥胖。心脏病和糖尿病等患病风险增高。

Gareth Lim是UBC大学生命科学研究所的博士后研究员,他如此解释14-3-3蛋白的重要性:“人体获取脂肪和出现肥胖的原因无外乎两种:脂肪细胞数目增多和体积增大。而14-3-3蛋白在脂肪细胞数量增多和体积增大两方面都起到积极作用。”

尽管两组小鼠进食相同种类和数量的食物,14-3-3蛋白相关基因表达的小鼠相比未表达的小鼠而言,体内白色脂肪的含量要增多50%,且小鼠体型更硕大,更圆润,比进食高卡热量饮食的小鼠白色脂肪含量增多22%。

这项研究发表在Nature Communications杂志上,该项目为期4年,研究人员认为他们发现了14-3-3蛋白的产生与机体的肥胖存在关联,因此今后将会出现一种新的药物以治疗肥胖。 即通过抑制14-3-3蛋白相关基因的表达,使机体内减少14-3-3蛋白的出现,从而解决民众烦恼的肥胖问题。但是到现在为止,我们仍无法得知这个基因是如何影响机体肥胖的。这项研究表明,医疗机构可以尝试开辟新的途径,换一种角度解决患者的肥胖问题。虽然药物疗法可用于治疗肥胖,但是药物的效果因人而异,且存在一定的副作用,因此,饮食管理和规律锻炼必不可少。
