Abstract
- Arsenic trioxide (As <subscript>2</subscript> O <subscript>3</subscript> ) induces cell apoptosis and reduces the invasive and metastatic activities in various cancer types. However, the role of As <subscript>2</subscript> O <subscript>3</subscript> in ovarian cancer angiogenesis remains unclear. In this study, we investigated the role of As <subscript>2</subscript> O <subscript>3</subscript> in ovarian cancer angiogenesis and found that a low concentration of As <subscript>2</subscript> O <subscript>3</subscript> causes no effects on epithelial ovarian cancer cell viability or apoptosis. Moreover, we found that As <subscript>2</subscript> O <subscript>3</subscript> -treated epithelial ovarian cancer cells demonstrate a reduced tube formation of endothelial cells in Matrigel. In addition, As <subscript>2</subscript> O <subscript>3</subscript> -treated epithelial ovarian cancer cells show a decreased VEGFA, VEGFR2 and CD31 mRNA expression. As per the underlying mechanisms involved in As <subscript>2</subscript> O <subscript>3</subscript> treatment, we found that As <subscript>2</subscript> O <subscript>3</subscript> inhibits VEGFA and VEGFR2 expression that thereby inhibits the VEGFA-VEGFR2-PI3K/ERK signaling pathway. This leads to a suppression in both VEGFA synthesis and angiogenesis-related gene expression. A decreased VEGFA synthesis and secretion also inhibits the VEGFA-VEGFR2-PI3K/ERK signaling pathway in human umbilical vein endothelial cells (HUVECs). In summary, our results may provide strategies for the use of As <subscript>2</subscript> O <subscript>3</subscript> in the prevention of tumor angiogenesis.
