The role of growth differentiation factor (GDF)-11 in cardiac diseases has not been fully determined. Our study revealed that GDF-11 is not essential for myocardial development and physiological growth, whereas its absence exacerbates heart failure under pressure overload condition via impairing the responsive angiogenesis. GDF-11 induced VEGF expression in CMs by activating the Akt/mTOR pathway. The effect of endogenous GDF-11 on the heart belongs to local self-regulation of myocardial tissue, rather than a way of systemic regulation.
生长分化因子(GDF)-11在心脏疾病中的作用尚未完全明确。我们的研究表明,GDF-11对心肌发育和生理性生长并非必不可少,然而,在压力超负荷情况下,其缺失会通过损害反应性血管生成而加剧心力衰竭。GDF-11通过激活Akt/mTOR途径诱导心肌细胞中血管内皮生长因子(VEGF)的表达。内源性GDF-11对心脏的作用属于心肌组织的局部自我调节,而非一种全身调节方式。
