线粒体融合分裂与自噬：运动生理研究的新视角
线粒体 自噬 线粒体自噬 线粒体融合分裂
2015/8/18
自噬是广泛存在于真核细胞内的一种溶酶体依赖性的降解途径，它与泛素-蛋白酶体系统共同维持蛋白质及细胞器更新，对于维持细胞的稳态具有重要意义。线粒体作为真核生物最主要的细胞器之一，其代谢更新对于细胞状态有意义深远。作为线粒体更新的主要机制，线粒体自噬的发生逐渐引起关注。关于损伤的线粒体是如何通过自噬途径被移除的，其相关机制仍旧不明了。有研究认为线粒体融合分裂与线粒体自噬的发生关系密切，可能是其调控的关...
运动和营养素的细胞内作用靶点——线粒体：阿尔茨海默病防治的新思路
阿尔茨海默病 线粒体 运动 营养素
2015/8/18
阿尔茨海默病（Alzheimer Disease，AD）是一种与年龄相关的神经退行性疾病，目前缺乏有效的防治方法。研究表明，适量的运动和营养素，可以通过改善脑内线粒体的功能，延缓认知功能衰退和阿尔茨海默病的发生和发展。我们将这类靶向于线粒体的营养素或天然产物定义为线粒体营养素。本文从线粒体角度，综述了运动和线粒体营养素对阿尔茨海默病中神经元的作用机制，为阿尔茨海默病的防治提供新的思路。
运动和MicroRNAs
运动 小分子RNA 骨骼肌
2015/8/18
运动通过增加机械负荷或代谢应激可诱导不同的适应，从而调节生理系统的功能，如骨骼肌、心血管和神经系统。MicroRNAs（miRNA）是非编码、小分子mRNA，作为基因转录后的阻遏物。MicroRNAs通过直接阻遏或降解mRNA，沉默mRNA转录，最终影响蛋白的丰度。实验研究业已发现耐力和力量练习，骨骼肌特异miRNA的表达变化。在运动方面研究MicroRNAs分子行为可助于认识运动治疗的作用。

Magnesium supplementation has previously shown reductions in blood pressure of up to 12 mmHg. A positive relationship between magnesium supplementation and performance gains in resistance exercise has...
Effects of protein type and composition on postprandial markers of skeletal muscle anabolism, adipose tissue lipolysis, and hypothalamic gene expression
Whey protein Egg protein Hydrolyzed protein
2015/7/30
Skeletal muscle analyses revealed that compared to CTL: a) phosphorylated (p) markers of mTOR signaling [p-mTOR (Ser2481) and p-rps6 (Ser235/236)] were elevated 2–4-fold in all protein groups 90 min p...
Soy protein ingestion results in less prolonged p70S6 kinase phosphorylation compared to whey protein after resistance exercise in older men
Anabolic signalling Supplementation Aging
2015/7/30
The phosphorylation of p70S6 Kinase (p70S6K) is an important step in the initiation of protein translation. p70S6K phosphorylation is enhanced with graded intakes of whey protein after resistance exer...
