MALAT1 and cancer: The results of CCK-8 and trypan blue staining assays showed that compared with noncervical cancer cell End/E6E, knockdown of LncRNA MALAT1 significantly reduced the viability and cell number of Hela, C33A, Caski, and SiHa cells, whereas overexpression of LncRNA MALAT1 increased these features (Figures 3(a)–3(j)).
