CDCA2 and renal cell carcinoma: To further confirm the results of our m6A-seq data, we analyzed gene-specific m6A-IP qPCR assays for several hypermethylated genes (CDCA2, CHAT, TGFA, PLOD2, and EGLN1) and hypomethylated genes (MUC15, HRG, HIF1A, ZNF677, and PAK6), which might participate in RCC development.
