摘要:

目的:研究在血小板源性生长因子(platelet-derived growth factor-BB,PDGF-BB)诱导下姜黄素对血管平滑肌细胞(vascular smooth muscle cell,VSMCs)增殖以及人第10号染色体缺失的磷酸酶及张力蛋白同源基因(phosphatase and tensin homology deletedon chromosome ten,PTEN)的影响,为侗族药物“姜黄”的临床应用提供更丰富的实验依据。方法:用20 ng/mL PDGF-BB孵育大鼠VSMCs 24 h,建立细胞增殖模型。MTT和CCK-8法观察姜黄素对VSMCs的细胞活性的影响,流式细胞术检测细胞周期,细胞划痕实验观察细胞迁移力,RT-PCR和Western blot观察PTEN mRNA、PTEN蛋白以及磷酸化PTEN(p-PTEN)蛋白的表达情况。结果:在20 ng/mL PDGF-BB的诱导下,10、30 μmol/L的姜黄素可显著抑制VSMCs增殖,以10 μmol/L姜黄素为最佳作用浓度,其不仅可以使细胞周期中G0/G1期比例明显升高,S期比例降低,还能显著抑制VSMCs迁移。同时可以上调PTEN mRNA和PTEN蛋白的表达,下调p-PTEN蛋白的表达。结论:姜黄素可以抑制PDGF-BB诱导的血管平滑肌细胞增殖与迁移,其对PTEN的影响,可能与上调PTEN mRNA和PTEN蛋白,下调p-PTEN蛋白相关。

Abstract:

AIM: To study the effects of curcumin on the proliferation of vascular smooth muscle cells (VSMCs) and the deletion of phosphatase and tensin homology deletedon chromosome ten (PTEN) induced by platelet-derived growth factor-BB (PDGF-BB) and to provide more abundant experimental basis for the clinical application of Dong nationality medicine "Curcuma longa". METHODS: The proliferation model of VSMCs was established by incubating with PDGF-BB (20 ng/mL) for 24 h. The cell activity was observed by MTT and CCK-8, cell cycle and cell migration were detected by flow cytometry and cell scratch assay, respectively. The effects of PTEN mRNA, PTEN protein and phosphorylated PTEN (p-PTEN) protein were observed by RT-PCR and Western blot. RESULTS:10, 30 μmol/L of curcumin was significantly inhibited the proliferation and migration of VSMCs induced by PDGF-BB (20 ng/mL). 10 μmol/L curcumin was used as the optimum concentration, it could not only increase the ratio of G0/G1 phase and decrease the proportion of S phase, but also inhibit the migration of VSMCs. At the same time, it could up-regulate the expression of PTEN mRNA and PTEN protein, down-regulate the expression of p-PTEN protein. CONCLUSION: Curcumin can inhibit the proliferation and migration of VSMCs induced by PDGF-BB. The effect of curcumin on PTEN may be related to the up-regulation of PTEN mRNA and PTEN proteins, down-regulation of p-PTEN proteins.
