METTL14 and gestational diabetes: The mRNA level of the methyltransferase METTL14 was significantly decreased in placental samples from patients with GDM compared with controls, and methylated RNA immunoprecipitation sequencing (MeRIP-seq) data revealed that most m6A peaks were reduced in 3’-untranslated regions (UTRs) and coding sequences (CDSs) near stop codons in placental samples from patients with GDM (77).
