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.
