Abstract:
Objective To investigate the effect and its mechanism of D-pinitol on advanced glycation end products(AGEs)-induced proliferation and migration in mouse aortic vascular smooth muscle cells (VSMC).Methods VSMCs were isolated from mouse aorta and cultured in vitro.Effects of different concentrations of D-pinitol on proliferation and migration of VSMCs were observed by using the AGEs-induced glycosylation injury model of VSMCs.Cell proliferation and migration were detected by CCK-8 assay and cell scratch,respectively.The protein expression levels of transforming growth factor-β1(TGF-β1),p-smad2,p-smad3 and asporin were determined by Western blot.Results Compared with control group,AGEs group showed the increased protein expression levels of asporin,TGF-β1,p-smad2 and p-smad3 (40.06 ± 4.50 vs.17.47 ± 0.57),(55.25 ± 2.07 vs.14.42± 2.07),(0.97 ± 0.02 vs.0.47 ± 0.02),(0.45±0.01 vs.0.26 ± 0.02),all P＜ 0.01.Compared to AGEs group,D-pinitol group could inhibit the cell proliferation and migration and cause dose-dependent decreases of protein expressions of TGF-β1,p-smad2,p-smad3 and asporin(P ＜ 0.05 or P＜0.01).Conclusions D-pinitol can inhibit AGEs-induced cell proliferation and migration in mouse aortic VSMCs.Asporin may participate in the VSMCs extracellular matrix remodeling via TGF-β/smad pathway.
