ABSTRACT

Objective To examine the inhibition effect of zoledronic acid (ZOL) on malignant metastasis of human esophagus squamous cell carcinoma (ESCC) cells and to analyze its molecular mechanisms.Methods EC9706 and EC109 cells were treated with ZOL,and then MTT assay,adhesion and invasion assay were performed to observe the inhibitory effect of As2O3 on proliferation and metastasis of esophagus carcinoma cells.The expression of metastasis-related proteins was detected by Western blotting.Results Exposure to ZOL significantly presented suppressive functions on growth and metastasis of both kinds of cancer cells,in a dose-dependent manner(P< 0.05).Additionally,the expression level of occludin was increased after ZOL treatment by suppressing transcriptional factor Slug.Transfection of Slug could reverse anti-metastasis of ZOL.Conclusion ZOL possesses a significant anti-metastasis function on ESCC cells,mainly through repressing Slug to restore occludin expression.

ABSTRACT

Objective To investigate the molecular mechanism of As 2 O3 in suppressing metastasis of esophagus carcinoma cells.Methods The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) assay, adhesion and invasion assay were performed to observe the inhibitory effect of As 2 O3 on proliferation and metastasis of esophagus carcinoma cells .The expressions of matrix metalloproteinases ( MMP)2, MMP9, E-cadherin, and protein tyrosine phosphatase receptor-type O ( PTPRO) were analyzed with Western blot .Results Exposure to As 2 O3 significantly presented suppressive functions on growth and metastasis of esophagus carcinoma cells in a dose-dependent manner ( P <0.01 ) .Additionally , MMP2 and MMP9 expressions were increased after treatment with casticin ( P <0.01 ) , whereas E-cadherin and PTPRO expressions were down-regulated ( P <0.01 ) .Conclusions As2 O3 had a significant function to inhibit proliferation and metastasis of esophagus carcinoma cells .
