YTHDF2 and neoplasm: To understand the mechanism of YTHDF2 in tumorigenesis, we explored the R2 (http://hgserver1.amc.nl/cgi-bin/r2/main.cgi) database and found that the genes correlated with YTHDF2 are enriched in tumor-associated biological processes such as DNA repair, apoptosis, and the cell cycle (Additional file 1: Figure S9A).
