For instance, Piwi-interacting RNA (piRNA)-14633 interacts with the 3’UTR of METTL14 to enhance the stability of METTL14 mRNA and encouraged the methylase activity of METTL14, promoting the m6A methylation levels of the downstream target (CYP1B1), and subsequently promoting the expression of CYP1B1, which in turn contributed to the oncogenesis of cervical carcinoma [53]. This evidence concerns the gene CYP1B1 and cervical carcinoma.
