Abstract

FoxM1 is a specific transcription factor that has an important function in aggressive human carcinomas, including cervical cancer. However, the specific function and internal molecular mechanism in cervical cancer remain unclear. In this study, RNAi-mediated FoxM1 knockdown inhibited cell growth. This process also decreased the migration and invasion activities of HeLa cells in vitro. Downregulation of FoxM1 inhibited tumor growth and angiogenesis in vivo. In addition, the expressions of uPA, matrix metalloproteinase (MMP)-2, MMP-9 and VEGF were significantly decreased in vitro and in vivo. These results suggested that the inactivation of FoxM1 could be a novel therapeutic target for cervical cancer treatment.
