摘要: 摘要: 目的 研究 Gli 抑制剂 GANT61 对人食管腺癌细胞 OE19 和 OE33 的生长抑制作用及其可能作用机制。 方法 常规培养 OE19 和 OE33 细胞。MTS 法检测不同浓度 GANT61(30、 20、 13.333 3、 8.888 8、 5.925 9、 3.950 6、 2.633 7、 1.755 8、 1.170 5 μmol /L)对 OE19 和 OE33 细胞活力的影响, 以半数抑制浓度(IC50)表示。OE19 和 OE33 细 胞分别设治疗组(10 μmol /L GANT61 处理)和 DMSO 组(常规 DMSO 处理)。实时荧光定量 PCR 检测 2 组 OE19 和 OE33 细胞中 Gli1 和 Gli2 mRNA 的表达。Western blot 法检测 2 组 OE19 和 OE33 细胞的 Gli1 、 Gli2 和 CyclinD1 蛋 白表达量的变化。Transwell 侵袭实验观察 2 组 OE19 和 OE33 细胞 24 h 侵袭能力的变化。结果 GANT61 作用于 OE19 和 OE33 细胞 72 h 的 IC50值分别是 8.08 和 9.65 μmol/L。治疗组 OE19 和 OE33 细胞的 Gli1、 Gli2 mRNA 和蛋 白表达水平均低于 DMSO 组,CyclinD1 蛋白表达水平较 DMSO 组亦显著降低(P<0.05)。治疗组在 OE19 和 OE33 细胞中的穿膜细胞数较 DMSO 组明显减少(P<0.01)。结论 GANT61 可以通过下调 Gli1 和 Gli2 mRNA 及蛋白水 平的表达, 抑制食管腺癌细胞的生长和侵袭; Hedgehog 信号转导通路异常活化和食管腺癌的发生和发展有关。

Abstract: Abstract:Objective To study the inhibitory effects of GANT61, as an inhibitor of Gli, on the growth of human esophageal adenocarcinoma cell lines OE19 and OE33, and their mechanisms thereof. Methods After treating with different concentrations of GANT61(30, 20, 13.333 3, 8.888 8, 5.925 9, 3.950 6, 2.633 7, 1.755 8, 1.170 5 μmol/L), the cell viabilities of OE19 and OE33 were detected by MTS method, which expressed by IC50. The Gli1and Gli2 mRNA expressions treated with GANT61(10 μmol/L GANT61) or DMSO for 24 h were detected in OE19 and OE33 cell lines by real time fluorescence quantitative PCR. The protein expressions of Gli1, Gli2 and CyclinD1 treated with GANT61 or DMSO for 24 h were detected in OE19 and OE33 cell lines by Western blot assay. Transwell invasion assay was performed to evaluate the inhibiting effect on OE19 and OE33 cell invasion by the treatment of GANT61 or DMSO. Results The IC50 of GANT61 was 8.08 μmol/L in OE19 and 9.65 μmol/L in OE33 cells. Compared with DMSO group, Gli1 and Gli2 mRNA expressions and Gli1,Gli2 and CyclinD1 protein expressions were significantly decreased in OE19 and OE33 cells of GANT61 group (P< 0.05). The number of penetrating cells was significantly reduced in OE19 and OE33 cells of GANT61 group compared with that of DMSO group (P < 0.01). Conclusion GANT61 can inhibit the growth and invasion of esophageal neoplasms cells by down-regulating Gli1 and Gli2 mRNA expression, which indicates that Hedgehog signaling pathway may play an important role in carcinogenesis and progression of esophageal adenocarcinoma.
