MGAT3 and cervical carcinoma: dCas9-TET1CD could demethylate hepatocyte nuclear factor (HNF)1A and Beta-1,4-mannosyl-glycoprotein 4-beta-N-acetylglucosaminyltransferase (MGAT3) genes in BG1 (human ovarian adenocarcinoma) cells [158], and telomeric repeat-containing RNA (TERRA) in HeLa (human cervix carcinoma) and T98G (human glioblastoma) cell lines [159].
