Abstract:
Objective To investigate the effect of protein kinase B on calcifition of human aorta vascular smooth muscle cells(HASMCs) stimulated by advanced glycation end products (AGEs). Methods HASMCs were cultured in vitro and randomly divided into control group,DMSO group,AGEs group and AGEs+LY294002 group. The calcification of each group was examined by von Kusaa;the expression of protein was detected by west-ern blot and ALP levels in each group by Elisa. Results The expression of bone morphogenetic protein-2(BMP-2)and osteoprotegerin(OPG)in AGEs group was significantly higher than that in control group(P < 0.05). The expression of phosphorylated AKT in AGEs group was significantly higher than that in control group (P < 0.05), and it was time and concentration dependent. Compared with that in AGEs group ,the expression of BMP and OPG in AGEs + LY294002 group was significantly decreased (P < 0.01). Conclusion AKT signaling pathway may play an important role on calcifition of HASMCs caused by AGEs.
