Arsenic sulfide inhibits cell migration and invasion of gastric cancer in vitro and in vivo.

ABSTRACT:

Background

We previously showed that arsenic sulfide (As4S4) induced cell cycle arrest and apoptosis in several human solid tumor cell lines, including those of gastric cancer. In this study, we investigated the effect of As4S4 on the migration and invasion of gastric cancer cells both in vitro and in vivo.

Methods

The human gastric cancer cell lines AGS and MGC803 were selected as in vitro models. Wound-healing migration assay and Transwell invasion assay were carried out to determine the effects of As4S4 on cell migration and invasion. The expressions of E-cadherin, β-catenin, Sp1, KLF4, and VEGF were measured by Western blotting analysis. The activities of matrix metalloproteinase (MMP)-2 and MMP-9 in MGC803 cells were demonstrated by zymography assay. A mouse xenograft m
