Hippo: A New Hub for Atherosclerotic Disease.

Abstract

Hippo, an evolutionarily conserved kinase cascade reaction in organisms, can respond to a set of signals, such as mechanical signals and cell metabolism, to maintain cell growth, differentiation, tissue/organ development, and homeostasis. In the past ten years, Hippo has controlled the development of tissues and organs by regulating the process of cell proliferation, especially in the field of cardiac regeneration after myocardial infarction. This suggests that Hippo signaling is closely linked to cardiovascular disease. Atherosclerosis is the most common disease of the cardiovascular system. It is characterised by chronic inflammation of the vascular wall, mainly involving dysfunction of endothelial cells, smooth muscle cells, and macrophages. Oxidized Low density lipoprotein (LDL) damages the barrier function of endothelial cells, which enter the middle membrane of the vascular wall, accelerate the formation of foam cells, and promote the occurrence and development of atherosclerosis. Autophagy is associated with the development of atherosclerosis. However, the mechanism of Hippo regulation of atherosclerosis has not meant to be clarified. In view of the pivotal role of this signaling pathway in maintaining cell growth, proliferation, and differentiation, the imbalance of Hippo is related to atherosclerosis and related diseases. In this review, we emphasized Hippo as a hub for regulating atherosclerosis and discussed its potential targets in pathophysiology, human diseases, and related pharmacology.
