MALAT1 and carcinoma: To verify our hypothesis and determine the regulatory role of LncRNA MALAT1 in cervical carcinoma, we first compared the expression levels between paracarcinoma tissues and carcinoma tissues in 15 cervical cancer patients, as well as in the normal cervical epithelial cell line (End1/E6E) and cervical tumor cell lines (Hela, C-33A, Caski, and SiHa).
