YWHAG and gastric cancer: Subsequently, in order to further analyze the relationship between PD-1 and m6A regulators in gastric cancer, we found that in gastric cancer cells, PD-1/L1 and METTL3, WTAP, HNRNPD, ZC3H7B, METTL14, FTO, PCIF1, HNRNPC, YTHDF2, YTHDF1, YWHAG, ZC3H13 and MSI2A were significantly correlated in gastric cancer cells.
