Abstract
This study aims to research the effect of HSP65 on the expression of adhesion molecules in activated mice heart endothelial cells (MHECs), which were from myocardial tissue of newborn animals. We used different concentrations of LPS as potent inducers to stimulate MHECs, adhesion molecule expression in vitro, including intercellular adhesion molecule-1 (ICAM-1), vascular adhesion molecule-1 (VCAM-1), E-, and P-selectins, then compared the mRNA and protein levels of adhesion molecules expression with or without HSP65 treatment at different levels. The optimal concentration of LPS to induce MHECs adhesion molecule expression is 100ng/ml; HSP65 treatment significantly reduced the mRNA and protein levels of MHECs' ICAM-1, VCAM-1, E-, and P-selectins expression (p < 0.05), and the optimal concentration of HSP65 in inhibiting MHECs activation is 0.8ng. HSP65 has the inhibitory effect on adhesion molecules expression in activated MHECs.
