摘要: 目的:检测小分子抑制剂ICG-001对食管鳞癌细胞增殖的抑制作用并探讨其分子机制。方法:使用50和100 μmol/L的小分子抑制剂ICG-001处理食管鳞癌细胞系KYSE410和KYSE450,以溶剂DMSO处理细胞作为对照,进行细胞增殖活力、集落形成能力、细胞周期分布及凋亡检测;分别使用实时荧光定量PCR(qPCR)和Western blot检测ICG-001处理细胞中相关分子(SKP2、Survivin和TCF4)mRNA和蛋白水平的表达变化。结果:与对照组比较,ICG-001处理可显著抑制食管鳞癌细胞系KYSE410和KYSE450的增殖活力和集落形成能力,并可显著诱导细胞发生G0/G1期阻滞(P<0.01);SKP2、Survivin和TCF4的mRNA和蛋白表达水平在ICG-001处理组均显著降低(P<0.01)。结论:ICG-001可显著抑制食管鳞癌细胞的增殖活力和集落形成能力,并可诱导细胞发生G0/G1期阻滞,该作用可能与其抑制β-catenin/TCF4的转录活性及其下游分子Survivin和SKP2的表达有关。

Abstract: OBJECTIVE:To investigate effects of small molecule inhibitor ICG-001 on malignant phenotypes of esophageal squamous carcinoma (ESCC) cells and to explore its molecular mechanisms. METHODS:The ESCC cell lines KYSE410 and KYSE450 were treated with ICG-001 of 50 and 100 μmol/L,or with solvent DMSO as control. Treated cells were evaluated for cell proliferation viability,colony formation ability,cell cycle distribution and apoptosis. mRNA and protein expression of related molecules (SKP2,Survivin,and TCF4) were detected by real-time PCR (qPCR) and Western blot. RESULTS:Compared with the control group,ICG-001 treatment significantly inhibited the proliferation and colony formation ability of KYSE410 and KYSE450,and significantly induced G0/G1 phase arrest (P<0.01). In addition,expression levels of SKP2、Survivin and TCF4 were significantly decreased (P<0.01). CONCLUSION:ICG-001 significantly inhibited the proliferation viability and colony formation ability,and induced G0/G1 phase arrest of the two ESCC cell lines. The mechanisms may be related to the inhibition of b-catenin/TCF4 transcriptional activity and the expression of downstream molecules:Survivin and SKP2.
