In mammal adolescence, cardiomyocytes rapidly exit the cell cycle, and heart regeneration in adults is limited after cardiac injury. Recent work by Li et al. in Nature revealed that inhibition of fatty acid oxidation can rewire cell metabolism and lead to epigenetic reprogramming of cardiomyocytes to an immature state that facilitates cardiomyocyte cell-cycle reentry and heart regeneration in adult animals.
在哺乳动物青春期，心肌细胞迅速退出细胞周期，而成年后心脏损伤后的再生能力有限。最近，Li 等人在《自然》杂志上的研究表明，抑制脂肪酸氧化可以重新连接细胞代谢，并导致心肌细胞的表观遗传重编程为不成熟状态，从而促进成年动物心肌细胞的细胞周期再进入和心脏再生。
