ZC3H13 and neoplasm: In agreement with previous reports (12, 42), our study also identified METTL14 as a tumor suppressor gene in breast cancer, as well as ZC3H13, while other m6A “writers” (METTL3, RBM15, and RBM15B) were not dysregulated in tumor tissues compared with normal control based on the data from TCGA and Oncomine databases.
