A new study indicates that proteins in the sarcomere complex are stochastically removed and degraded and are replaced by newly translated proteins. Sarcomere turnover occurs at a similar rate within cardiomyocytes and across the heart and slows with ageing.

通过蛋白质的单向替换来改变心脏肌节


一项新的研究表明，肌节复合体中的蛋白质被随机去除和降解，并被新翻译的蛋白质取代。心肌细胞内和整个心脏的肌节周转率相似，并且随着年龄的增长而减慢。
