近日,一项刊登在国际杂志Nature Genetics上的研究报告中,来自阿伯丁大学的研究人员通过研究鉴别出了一种关键基因,该基因在确定人类机体肌肉质量上扮演着重要作用,机体的肌肉质量和一系列健康因子直接相关,其中就包括人类的寿命。

此前研究中,研究人员通过对老年人进行研究发现了机体肌肉量和预期寿命之间的关联。肌肉是机体中一种必不可少的关键组织,其能够发挥多种机体功能,比如让我们机体移动或者让我们自由呼吸。然而机体中骨骼肌肌肉量的水平却因人而异,存在着明显差异。

如果个体进行力量锻炼的话,其机体中骨骼肌量(skeletal muscle mass)的水平就会增加,但遗传因素在确定机体肌肉量的水平上同样扮演着相同重要的角色;如今研究人员通过研究鉴别出了影响小鼠机体肌肉量的关键基因,此外研究者此前通过研究还发现该基因和癌症的扩散存在直接关联,这对于后期科学家们开发新型疗法来靶向作用该基因就提供了新的思路和希望。

研究人员希望未来能够开发出新型药物来帮助他们理解该基因对肌肉组织的影响,如果有多重药物能够靶向作用相同的基因,那么研究者或许就能够找到对人类肌肉副作用娇小的药物。最后研究者表示,本文研究中所发现的新型基因在调节机体肌肉量上扮演着关键角色,同时未来他们有望开发出靶向作用该基因的新型药物来为治疗人类一系列疾病提供思路和希望。

eLife:sunitinib或可改善面肩肱型营养不良症患者的肌肉强度

近日,来自伦敦大学国王学院的牙科学院的研究人员发现,癌症药物sunitinib或可改善面肩肱型营养不良症(FSHD)患者的肌肉无力的情况,其研究结果已发表于eLife。研究中,研究人员发现RTK的一种类型——转染(RET)中重排——在肌肉干细胞或成肌细胞中的表达上调,RTK可表达DUX4 蛋白。该蛋白是由DUX4基因编码,位于FSHD患者的D4Z4区。FSHD患者中,D4Z4区域低甲基化,意味着需

J Proteome Res:在山里待上两周,你的血液就会发生改变

导语:经过一个晚上,人类的身体就会开始适应高海拔环境,而且这种适应能力所带来的生物学改变能够持续数月——也就是说,即使这个人后来返回了低海拔的环境,这种改变也会维持一段时间。最近,为了观察低氧环境中的多重变化如何影响红细胞的保有氧气的能力,科学家们有史以来第一次比较了登山者的血液——他们发现在几小时内登山者的血液就会发生改变。该研究反驳了一个持续了半个世纪的假说,该假说表明,与平均海拔地区的人相比
