In addition, this study detected the expression level of Malat1 in 4 CRC cell lines – HCT290, HCT116, SW480 and SW620 – and the human normal colorectal mucosa cell line FHC, finding that Malat1 expression was remarkably high in CRC cells in comparison with FHC (Fig. 1b). Here, MALAT1 is linked to colorectal carcinoma.
