YTHDC1 and colitis: To explore the molecular underpinning by which YTHDC1 in macrophages regulates colitis progression, we mined the published RNA‐sequencing database (GEO: GSE153512) concerning Mettl14f/f and Mettl14f/f;Lysm‐Cre BMDMs since YTHDC1 depends on RNA methylation to exert its functions.
