YTHDF2 and systemic lupus erythematosus: This study was aimed to explore the mRNA expression of m6A “writers” (METTL3, MTEEL14, and WTAP), “erasers” (FTO and ALKBH5), and “readers” (YTHDF2) in peripheral blood mononuclear cells (PBMCs) from systemic lupus erythematosus (SLE) patients and investigate the relation between their expressions with clinical features.
