摘要：AIM:To investigate the relationship between autophagy and calcification in vascular smooth muscle cells ( VSMCs) after platelet-derived growth factor (PDGF)-BB stimulation.METHODS:Cultured VSMCs were stimulated with PDGF-BB for different time, the expression of vascular calcification-related proteins and autophagy-related proteins were detected by Western blot .The interaction be-tween Beclin1 and PI3KC3 was detected by co-immunoprecipitation.RESULTS: The expression of BMP2 and ALP showed a trend from decline to rise.ALP slumped at 12 h, and BMP2 slumped at 6 h.Moreover, the expression of Beclin-1 showed a trend from riseto decline, and peaked at 12 h.The conversion of LC3-ⅠtoⅡincreased in a time-dependent manner , and peaked at 24 h.The ex-pression of BMP2 and ALP was increased in VSMCs incubated with PDGF-BB and autophagy inhibitor 3-MA, compared with PDGF-BB-stimulated VSMCs.Furthermore, the interaction between Beclin1 and PI3KC3 was enhanced at 6 h after PDGF-BB stimulated, peaked at 12 h, and kept in high level at 24 h.Moreover, the phosphorylation level of Beclin 1 was enhanced by PDGF-BB stimulation, and peaked at 6 h.CONCLUSION:Our findings demonstrate that PDGF-BB-induced autophagy inhibits VSMC calcification by en-hancing Beclin1 phosphorylation and interaction between Beclin 1 and PI3KC3.
