LINC00525 and colorectal cancer: To investigate the function of LINC00525, the expression of LINC00525 was knocked down in human colorectal cancer cells (SW620, SW1116, and LoVo) by transferring into LINC00525-specific small interfering RNA (si-525-1, si-525-2, and si-525-3), and meaningless small interfering RNA (si-NC) was used as a negative control.
