RBM15 and ovarian cancer: 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).
