Abstract
Small heat shock proteins (sHSPs) are common molecular chaperone proteins that function in various biological processes, and serve indispensable roles in maintaining cellular protein homeostasis and regulating the hydrolysis of unfolded proteins. HSP22 is a member of the sHSP family that is primarily expressed in the heart and skeletal muscle, as well as in various types of cancer. There have been important findings concerning the role of HSP22 in cardiovascular diseases. The aim of the present study was to provide insights into the various molecular mechanisms by which HSP22 functions in the heart, including oxidative stress, autophagy, apoptosis, the subcellular distribution of proteins and the promoting effect of proteasomes. In addition, drugs and cytokines, including geranylgeranylacetone, can exert protective effects on the heart by regulating the expression of HSP22. Based on increasingly abundant research, HSP22 may be considered a potential therapeutic target in cardiovascular diseases.
期刊介绍：
Molecular Medicine Reports is a monthly, peer-reviewed journal available in print and online, that includes studies devoted to molecular medicine, underscoring aspects including pharmacology, pathology, genetics, neurosciences, infectious diseases, molecular cardiology and molecular surgery. In vitro and in vivo studies of experimental model systems pertaining to the mechanisms of a variety of diseases offer researchers the necessary tools and knowledge with which to aid the diagnosis and treatment of human diseases.
