摘要:
目的 研究羟基红花黄素A(hydroxy safflower yellow A,HSYA)对退变软骨终板细胞周期的影响及相关机制。方法 用10 μg·L-1的IL-1β诱导软骨终板细胞建立炎症退变模型,分别制备不同浓度的HSYA培养基作为干预措施,采用CCK-8法检测不同浓度HSYA对细胞增殖的影响; 流式细胞仪检测HSYA对细胞周期的影响; real-time PCR检测细胞周期及凋亡相关基因p53、Bax、Bcl-xl表达; Western blot 检测细胞周期相关蛋白PCNA、p53、p21表达。结果 HSYA具有促进退变软骨终板细胞增殖的作用; HSYA降低退变组细胞周期S期比例; HSYA下调退变细胞p53、Bax mRNA 表达,上调Bcl-xl mRNA 表达; HSYA下调退变细胞周期蛋白p53、p21表达,上调PCNA表达。结论 HSYA具有改变退变软骨终板细胞周期及抑制其凋亡的作用。
Abstract:
Aim To explore the cell cycle changing effects of hydroxy safflower yellow A(HSYA)on cell cycle of degenerative end-plate chondrocytes and its mechanism.Methods The endplate cartilage cell was induced by IL-1β(10 μg·L-1)and established as inflammatory degeneration cell model, which was cured by HSYA in different concentrations.Then the changing of cell proliferation was analyzed in different time.Cell cycle was analyzed by using flow cytometry.The expression on cell cycle and apoptosis related genes, such as p53, Bax, Bcl-xl was detected with real-time PCR.Besides, the changing of cell cycle-related proteins PCNA, p53 and p21 was also detected by Western blot.Results The cell proliferation ability in degenerative endplate chondrocytes were promoted by HSYA with various concentrations.The ratio of S phase in degenerative group was reduced.The percentage of S phase cells decreased after treated with HSYA.Besides, HSYA down-regulated the gene expression of p53 and Bax, while it up-regulated the mRNA level of Bcl-xl.Further, HSYA decreased the cell cycle related protein expression of p53 and p21, and induced the expression level of PCNA.Conclusion HSYA could change the cell cycle and inhibit apoptosis in degenerative end-plate chondrocytes.
