重塑肌细胞显示出细胞凋亡和/或肥大的胚胎特征和经典特征之间的典型转换,代表死亡信号(即细胞凋亡)和生命信号(即肥大)。然而,成体肌细胞是终末细胞。通常它无法繁殖,死亡不是基因编程的(细胞凋亡),而是通过坏死发生的。重塑过程中细胞凋亡的恢复和肥大的发展可能是随着早期胚胎遗传程序的恢复而向胚胎表型转变的一部分。肥大和细胞凋亡是同一个“母亲”的“儿子”:局部组织神经内分泌-神经体液对肌细胞机械拉伸的反应,这是由于坏死的肌细胞对存活的肌细胞造成几何变化而产生的。正如预期的那样,生命和死亡周期受到多个自分泌系统的密切调节,其中一个系统通过一种名为 GP-130 的调节蛋白与白细胞介素 6 家族相关。 GP-130 的激活会减慢死亡信号,从而有利于肥大并减少纤维化。 (Circ J 2009;73:1973-1982)
Remodeling myocytes show a typical switch between the embryonic and classical features of apoptosis and/or hypertrophy representing a signal of death (ie, apoptosis) and a signal of life (ie, hypertrophy). The adult myocyte, however, is a terminal cell; usually it is unable to reproduce and death is not genetically programmed (apoptosis), but occurs by necrosis. The reinstatement of apoptosis and development of hypertrophy during remodeling could be part of the switch forward to the embryonic phenotype with reinstatement of the early embryonic genetic program. Hypertrophy and apoptosis are "sons" of the same "mother": the local, tissue neuroendocrine-neurohumoral response to a mechanical stretch of the myocytes consequent to the geometric changes imposed on the viable myocytes by the necrotic ones. As expected, the life and death cycle is very closely regulated by several autocrine systems, one of which is linked to the interleukin-6 family via a regulatory protein named GP-130. Activation of the GP-130 slows down the death signals, thus favoring hypertrophy and reducing fibrosis. (Circ J 2009; 73: 1973-1982)
