Abstract
Objective To detect the effect of glutahione S-transferases (GSTP1) expression on the migration,proliferation and apoptosis of cardiac microvascular endothelial cells (CMECs).Methods After obtaining CMECs from SD rats by enzymatic digestion method,the special plasmid of GSTP was transfected.The ability of migration,proliferation and apoptosis of CMECs were examined by using Transwell assay,methyl thiazol tetrazolium (MTT) assay and flow cytometry,respectively.Results The ability of migration of CMECs was significantly reduced in GSTP1 over-expression group as compared with control group (9.0 ±2.7 vs.12.8 ±2.5,P ＜0.05),and the ability of proliferation of CMECs was also obviously reduced in comparison with control group (0.26 ± 0.02 vs.0.05 ± 0.01,P ＜ 0.05).But the apoptotic index was increased significantly (P ＜ 0.05).Conclusion GSTP1 expression can effectively inhibit migration and proliferation,and promote apoptosis of CMECs. Key words: Glutahione S-transferases; Cardiac microvascular endothelial cells; Migration; Proliferation
