Background: Inactivation of the tumor suppressor gene microRNA-133b is a frequent event in various malignancies including colorectal cancer (CRC). The result of our previous research has found a statistically significant downregulation of microRNA-133b expression in human CRC cells, microRNA-133b can block the growth and metastatic progression of CRC cells in vitro and in vivo by targeting and repressing mesenchymal to epithelial transition factor. In this study, we identify the association between microRNA-133b, epithelial transition Factor expression and clinicopathological parameters. Metho...
