N6-methyladenosine (m6A), the most prevalent internal messenger RNA modification, plays critical roles in diverse biological processes. To characterize the potential involvement of METTL3 in macrophage function, transcriptome sequencing (RNA-seq) was performed in human THP1-derived macrophages with METTL3 depletion. We identified 266 genes that were differentially expressed in METTL3-depleted macrophages (= 1.5-fold change, P < 0.05), among which 44% (118 genes) were downregulated and 56% (148 genes) were upregulated. Notably, M2 macrophages activation-associated genes were robustly enhanced in METTL3-depleted macrophages. This study highlights the critical roles of m6A on regulation macrophages homeostasis. Overall design: The mRNA profiles of WT and METTL3-depleted macrophages under IL-4 stimulation. Three independent experiments were performed at each treatment.
