自噬在心血管疾病中的作用研究进展

Research progress on the role of autophagy in cardiovascular diseases

自噬是广泛存在于真核细胞中的生命现象。已有研究表明,自噬对维持细胞自身的稳定及细胞成分更新保持正常的生理状态起着至关重要的作用。近年来,研究发现自噬与生长发育、肿瘤以及心血管疾病的发生发展密切相关。进一步研究表明,自噬在不同病理环境下既能够促进血管生成,也能够抑制血管的生成。因此,阐释自噬在不同病理环境下调控血管生成的作用机制显得尤为关键。该文对自噬在心血管疾病中的作用尤其是对血管生成的作用研究进展进行综述,着重探讨自噬调控血管生成的作用机制,为后续的科学研究及指导临床提供重要参考。

Autophagy is a common phenomenon which widely ex-ists in eukaryotic cells. Researches have shown that autophagy plays a critical role in maintaining cellular hemostasis, cell com-ponents update and keeping a normal physiological state. In re-cent years, the study has found that autophagy is closely related to the growth, the development of cardiovascular diseases and tumors. Further studies show that in different pathological condi-tions, autophagy could both promote angiogenesis and inhibit the formation of blood vessels. Therefore, it is particularly critical to elucidate the mechanisms of autophagy in the regulation of angio-genesis in different pathological conditions. The role of autophagy in cardiovascular diseases especially in the regulation of angio-genesis is discussed in this paper. Besides, the paper also in-cludes the discussion about the mechanisms of autophagy in the regulation angiogenesis, which may provide references for follow-up research and clinical treatment.
