Background: The 5-year survival of colorectal cancer (CRC) has had no obvious improvement during the past decades, although a significant progress in treatments has been established. The molecular mechanisms that drive the progression of CRC are still unclear. This study aims to determine the biological activities of linc01615 and its regulatory microRNAs in CRC cells. Methods: The expression of linc016150 and miR-491-5p was measured in six CRC cell lines and one normal colon mucosal epithelial cell line. Their effects on cell proliferation, apoptosis, invasion, and migration were tested in Ca...
