Abstract

AIM:To explore the effect of neuropeptide Y on expression of apoptosis associated genes and proliferation in vascular smooth muscle cells(VSMC). METHODS: The proliferation activity of VSMC was dterminded by MTT colorimetry. The average fluorescence intensity that represented VSMC nuclear antigen (PCNA) and bcl-2, bax, fas expressions was quantitatively measured by fluorescence immunohistochemistry. RESULTS: Compared with control, the expressions of bcl-2, bax, fas, PCNA and the VSMC proliferation activity in VSMC treated with NPY were significantly increased. CONCLUSION:NPY may increase the expression of apoptosis associated genes in VMSC and promote its proliferation.
