[Fibroblast growth factor 21 plays a protective role in cardiovascular diseases by inducing autophagy].

Fibroblast growth factor 21 (FGF21) is a growth factor with endocrine function in the fibroblast growth factor family. Previous reports have shown that FGF21 is involved in the regulation of energy metabolism and plays a protective role in cardiovascular diseases such as coronary heart disease, diabetes, non-alcoholic fatty liver disease and so on. Recent studies have found that FGF21 can induce autophagy in a variety of tissues and organs, and autophagy is involved in many pathological processes of cardiovascular diseases, including vascular calcification, atherosclerosis, and myocardial ischemia-reperfusion injury. Therefore, FGF21 may play a protective role in a variety of cardiovascular diseases by regulating autophagy. This article reviews the research progress on the protective role of FGF21 in cardiovascular diseases by inducing autophagy.
