Two GEO databases demonstrated that 7 readers (HNRNPC, IGF2BP1, IGF2BP2, IGF2BP3, RBMX, YTHDC2, and YTHDF2) and 3 writers (METTL3, RBM15, and RBM15B) were more highly expressed in ovarian cancer than in ovarian surface epithelium or normal peritoneum tissues (GEO14407 and GEO12470, Figure 2a,b). The gene discussed is YTHDF2; the disease is ovarian carcinoma.
