ABSTRACT
AIM:
To explore the role of adrenomedullin (AM) in tissue factor (TF) and TFPI expression in HUVECs stimulated with oxLDL and to investigate its possible signal transduction pathway.METHODS:
Using chromogenic assay and RT-PCR technique, TF and TFPI protein activity and mRNA level in cultured HUVECs were observed. The signal transduction pathway of AM action was further analyzed by applying Rp-cAMP (cAMP antagonist), PD098059 (MAPK inhibitor) and H7 (PKC inhibitor).RESULTS:
AM inhibited TF protein activity and mRNA expression in HUVECs treated with oxLDL in a concentration-dependent fashion; AM alone increased TFPI protein activity and mRNA expression in concentration-dependent and time-dependent manner. Moreover, AM reversed the decrease in TFPI protein activity and mRNA level caused by oxLDL; AM-induced TFPI expression was inhibited by cAMP and MAPK inhibitors.CONCLUSION:
AM can reverse the effects of oxLDL on TF and TFPI expression in HUVECs, which can help improve the state of blood coagulation in atherosclerosis and delay development of atherosclerosis.
