METTL14 and neoplasm: Many research studies reported that related factors that regulate m6A could affect spermatogenesis (ALKBH5, METTL3), development (METTL3, FTO, ALKBH5), immunity (METTL3), UV-induced DNA damage response (METTL3, FTO), tumor metastasis (METTL14), stem cell renewal (METTL14), adipocyte differentiation (FTO), cellular development and differentiation, cell division, and several other life processes [13].
