柚皮素通过TGF-β1/Smad通路抑制瘢痕疙瘩成纤维细胞增殖、迁移和胶原合成
Naringenin inhibits proliferation,invasion and collagen synthesis in keloid fibroblasts by regulating TGF-β1/Smad signaling pathway
摘要
Abstract
Objective To explore the effects and molecular mechanisms of naringenin(Nar)on the proliferation,migration and collagen synthesis of keloid fibroblasts(KFs).Methods KFs were divided into control group and Nar group treated with Nar at concentrations of 10,25,50,100 and 150 µmol/L,and the effects of Nar on the proliferation of KFs were analyzed using CCK-8 assay.Western blot was performed to detect the effects of Nar on the expression levels of Col-1,FN,α-SMA,and MMP9,and the expression levels of Smad2/3 and p-Smad2/3 in KFs pretreated with TGF-β1.Results Compared with the control group,the proliferation ability of KFs was sig-nificantly inhibited by Nar at a concentration of ≥50 μmol/L(P＜0.05).Similarly,the migra-tion ability of KFs was significantly inhibited by 50 μmol/L of Nar(P＜0.01).Nar down-regula-ted the expression levels of Col-1,FN,α-SMA and MMP9 proteins in KFs,and p-Smad2/3 pro-teins in TGF-β1-treated KFs(all P＜0.05).Conclusion Nar may inhibit the proliferation,mi-gration and collagen synthesis of KFs by down-regulating the TGF-β1/Smad signaling pathway.关键词
