摘要: 目的:探讨Yes相关蛋白-转录增强相关结构域小分子抑制剂GNE-7883对食管鳞癌(ESCC)细胞恶性表型的影响及其分子机制。方法:以DMSO为对照,使用不同浓度(8、16、50和100 μmol/L)的GNE-7883处理ESCC KYSE410和KYSE510细胞24或48 h,检测细胞增殖活力、集落形成能力、迁移能力及凋亡率变化,并用逆转录实时荧光定量PCR(qRT-PCR)和Western blot法检测相关分子及信号通路活性蛋白的表达变化。结果:与对照组相比,50 和 100 μmol/L 的 GNE-7883 可显著抑制 KYSE410 和KYSE510细胞的增殖活力和集落形成能力(均为P<0.01),并可在血清饥饿条件下诱导KYSE410和KYSE510细胞发生显著凋亡(P<0.05)。同时,在血清饥饿条件下,8和16 μmol/L的GNE-7883可显著抑制KYSE410和KYSE510细胞的迁移能力(P<0.01)。分子水平检测结果显示,与对照组相比,常规培养条件下,50 和 100 μmol/L GNE-7883 处理后,ESCC 细胞中与增殖相关的 CTGF、CYR61、c-Myc、p-ERK和p-AKT蛋白表达水平明显降低(P<0.05);在血清饥饿条件下,50和100 μmol/L GNE-7883处理后,ESCC细胞中凋亡标志分子cleaved PARP、cleaved Caspase-3的表达水平明显升高(P<0.05),同时伴随CTGF、CYR61、Bcl-2、Bcl-xL、c-Myc、p-ERK和p-AKT蛋白表达水平的降低(P<0.05)。另外,在血清饥饿条件下,8和16 μmol/L GNE-7883处理后,ESCC细胞中CTGF、CYR61、MMP14及p-ERK蛋白表达水平亦较对照组明显下调(P<0.05)。结论:GNE-7883显著抑制ESCC细胞的增殖、迁移及存活能力,并可明显抑制MAPK/ERK和AKT/mTOR信号通路的活性,GNE-7883有可能成为ESCC治疗的候选药物。

Abstract: OBJECTIVE: To investigate effects of the Yes-associated protein-transcriptional enhanced associate domain (YAP-TEAD) small-molecule inhibitor GNE-7883 on malignant phenotypes and molecular mechanisms in esophageal squamous cell carcinoma (ESCC) cells. METHODS: KYSE410 and KYSE510 cells were treated with varying concentrations of GNE-7883 (8,16,50,and 100 μmol/L) for 24 or 48 hours,with DMSO as control. Cell proliferation, colony formation, migration, and apoptosis were assessed. Molecular expression changes were analyzed by qPCR and Western blot. RESULTS: Compared to controls,50 and 100 μmol/L of GNE-7883 significantly inhibited proliferation and colony formation in both cell lines (P<0.01),and induced apoptosis under serum-free conditions (P<0.05). Under serum-free conditions, 8 and 16 μmol/L of GNE-7883 significantly inhibited cell migration (P<0.01). Normal cultures treated with 50 and 100 μmol/L of GNE-7883 reduced CTGF,CYR61,c-Myc,p-ERK and p-AKT levels. Serum-free conditions with 50 and 100 μmol/L of GNE-7883 increased Cleaved PARP and Cleaved Caspase-3,while decreasd CTGF,CYR61, Bcl-2, Bcl-xL, c-Myc, p-ERK and p-AKT. Serum-free conditions with 8 and 16 μmol/L of GNE-7883 down-regulated CTGF, CYR61, MMP14, and p-ERK. CONCLUSION: GNE-7883 significantly suppressed proliferation, migration, and survival of esophageal squamous cell carcinoma (ESCC) cells and markedly inhibited activities of the MAPK/ERK and AKT/mTOR signaling pathways. It could be useful as a therapeutic candidate for ESCC.
