Autophagy in hypertensive heart disease

J Biol Chem. 2010 Mar 19;285(12):8509-14. doi: 10.1074/jbc.R109.025023. Epub 2010 Jan 29.

Abstract

In response to hypertension, the heart manifests robust hypertrophic growth, which offsets load-induced elevations in wall stress. If sustained, this hypertrophic response is a major risk factor for systolic dysfunction and heart failure. Extensive research efforts have focused on the progression from hypertrophy to failure; however, precise understanding of underlying mechanisms remains elusive. Recently, autophagy, a process of cellular cannibalization, has been implicated. Autophagy is activated during ventricular hypertrophy, serving to maintain cellular homeostasis. Excessive autophagy eliminates, however, essential cellular elements and possibly provokes cell death, which together contribute to hypertension-related heart disease.
