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.
