Abstract
BACKGROUND
The present study aimed to investigate the protective effects and mechanism of salidroside (SAL) on hypoxia/reoxygenation (H/R)-induced cardiomyocyte apoptosis and myocardial ischemia/reperfusion (I/R) injury.
METHODS
We set up an H/R H9c2 cell model in vitro and an I/R rat model in vivo. Cell viability, apoptosis and histopathologic evaluation were conducted.
RESULTS
The cell viability of H/R-induced cardiomyocytes was increased by pretreatment of SAL, whereas the release of lactate dehydrogenase, reactive oxygen species production, and apoptosis were decreased accompanied with reduced Cleaved-caspase-3 and Bax, and increased Bcl-2 expressions. The SAL restored mitochondrial membrane potential both in vitro and in vivo, and improved electrocardiographic abnormality, and attenuated myocardial apoptosis and injury in I/R-induced rats. The transfection of miR-378a-3p inhibitor counteracted the effects of SAL-induced increase of cell viability and decrease of cell apoptosis and mitochondrial membrane potential. SAL reduced the expression of insulin-like growth factor 1 receptor (IGF1R), and increased the expressions of PI3K and Akt, however, these alterations were blocked by miR-378a-3p inhibitor.
CONCLUSIONS
miR-378a-3p might participate in the protective effect of SAL in I/R-induced myocardial apoptosis via the IGF1R/PI3K/AKT signaling pathway.
