摘要：Bone morphogenetic protein-2 (BMP-2) plays an key role both in vascular development and pathophysiological processes. However, the mechanisms of oxidized low density lipoprotein (ox-LDL) and combinated with atorvastatin or probucol on BMP-2 expression are entirely unknown in human umbilical vein cells. Methods The HUVECs were treated by ox-LDL and combinated with atorvastatin, probucol. The expression of BMP-2, NF-κB65,PPARγ mRNA was examined by RT-PCR analysis and ELISA method. The MDA and SOD were detected by routine methods. Results Ox-LDL can induced BMP-2 mNRA expression, associated with NF-κB65 mNRA expression activation. Both atorvastatin and probucol can suppress BMP-2 and NF-κB65 expression induced by oxLDL and upregulate the expression of PPARγ. Furthermore, the increase of supernatant MDA levels and decrease of supernatant SOD levels resulted from oxLDL treatment can be reversed by probucol or atorvastatin. Conclusions OxLDL-induced BMP-2mNRA expression can be suppressed by atorvastatin and probucol, which may be accomplished by activating NF-κB65 expression and upregulating the expression of PPARγ. Our findings also indicate that that BMP-2 mNRA expression includes the activation of reactive oxygen species.
