摘要:«的 探索白藜芦醇(resveratrol)对宫颈癌细胞化疗敏感性的影响及其调控机制。沁 Hela/DDP细胞分为
4 组:Hela/DDP 组,resveratrol 组,顺钳(cisplatin, CDDP)组,resveratrol + CDDP 组。CCK-8 检测细胞活力及增殖。 流式细胞仪检测细胞周期及细胞凋亡。Western blot检测p21、CDK2、cyclinDl、caspase_9、caspase_3、Ecl-2和Eax表 达。结果 Hela/DDP细胞对CDDP的敏感性低于Hela细胞(PVO. 01)。白藜芦醇可增强H ela/DDP细胞对CDDP 的敏感性(P<0. 01)o白藜芦醇可提高CDDP对H ela/DDP细胞增殖的抑制作用(P<0. 01)o白藜芦醇可增强 CDDP 对 Hela/DDP 细胞 G1 期阻滞作用(P<0. 01)。resveratrol 组和 CDDP 组 p21 表达高于 Hela/DDP 组,CDK2 和 cyclinDl 低于 Hela/DDP 组(P<0. 01) 0 与 CDDP 组相比,resveratrol+CDDP 组 P21 表达升高,CDK2 和 cyclinDl 表达降低(P<0. 01)o白藜芦醇可提高CDDP对Hela/DDP细胞凋亡的诱导作用(P<0. 01)o resveratrol组和 CDDP 组 caspas&3、caspasw9 和 Bax表达高于 Hela/DDP 组,Ecl-2 表达低于 Hela/DDP 组(P<0. 01)o 与 CDDP 组 相比,resveratrol+CDDP组caspase-3caspase-9和Bax表达升高,Ecl-2表达下降(P<C0. 01) o结论 白藜芦醇可能 通过诱导细胞周期阻滞及细胞凋亡而增强宫颈癌细胞的化疗敏感性。

ABSTRACT: Objective To explore the effect of resveratrol on the chemosensitivity of cervical cancer cells and
its regulatory mechanism. Methods Hela/DDP cells were divided into four groups: Hela/DDP group, resveratrol group, CDDP group, and resveratrol+CDDP group. Cell viability and proliferation were detected by CCK-8. Cell cycle and apoptosis were tested by flow cytometry. The expressions of p21, CDK2, cyclinDl, caspase-9, caspase-3, Bel 2 and Bax were measured by Western blot. Results The sensitivity of Hela/DDP cells to cisplatin was lower than that of Hela cells (PVO. 01). Resveratrol significantly enhanced Hela/DDP cells9 sensitivity to cisplatin (PV 0.01). The inhibition of CDDP on the proliferation of Hela/DDP cells was increased by resveratrol (PVO. 01). The G1 phase arrest of CDDP on Hela/DDP cells was enhanced by resveratrol (PVO. 01). The expression of p21 was higher in resveratrol group and CDDP group than in Hela/DDP group, and the expressions of CDK2 and CyclinDl were lower than in Hela/DDP group (PVO. 01). Compared with CDDP group, the expression of p21 in resveratrol + CDDP group was elevated with the decrease in CDK2 and cyclinDl expressions (PVO. 01). The induction of CDDP on the apoptosis of Hela/DDP cells was elevated by resveratrol (P<C0.01). The expressions of caspase-3, caspase-9 and Bax were higher in resveratrol group and CDDP group than in Hela/DDP group, and the expression of Bcl-2 was lower than in Hela / DDP group (PVO.01). Compared with CDDP group, apoptosis in
