Hepatocyte growth factor intervention to reduce myocardial injury and improve cardiac function on diabetic myocardial infarction rats

Abstract

Acute myocardial infarction (AMI) is recognized to be a severe threat to people’s health conditions and life quality. The accumulation of hepatocyte growth factor (HGF) in ischemic myocardium has been observed in both processes of experimental ischemia and reperfusion (I/R) and permanent coronary artery occlusion. The aim of the study was to investigate the effect of HGF on myocardial cell apoptosis, ventricular remodeling and cardiac function after myocardial infarction (MI) in diabetic rats, and to explore whether the effect is mediated by HGF/c-Met signaling pathway. MI significantly increases LVWI and RVWI and myocardial apoptotic index, and up-regulates the expression of HGF and c-Met at mRNA and protein levels in MI control group. The LVWI and RVWI, and myocardial apoptosis were reduced by treatment with HGF, which also increased the myocardial cell viability and the expression of HGF and c-Met. In summary, HGF significantly attenuates myocardial apoptosis and improves cardiac function after AMI in diabetic rats by further enhancing the activation of HGF/c-Met pathway.

The Efficacy of Transplanting Human Umbilical Cord Mesenchymal Stem Cell Sheets in the Treatment of Myocardial Infarction in Mice

“…In terms of cell survival and tissue regeneration, HGF is one of the most potent cell mitotic factors and a critical component of tissue wound repair [ 25 ]. HGF intervention has been shown to reduce tissue damage and improve cardiac function [ 26 , 27 ]. In our study, we showed that SCS transplantation induced HGF expression in MI tissue.…”
