Besides, the expression of LncRNA CARMN was measured in normal colon epithelial cell lines (HIEC‐6 and FHC) and several colon cancer cells (HCT116, SW480, SW620), and the results revealed that CARMN expression was significantly reduced in the colon cell lines of mutant p53 (Figure 1F). The gene discussed is CARMN; the disease is colonic neoplasm.
