PVR and cancer: Our results revealed that in GBM cancer cells, expression of CD274 (PD-L1), PDCD1LG2 (PD-L2), LGALS9 (Galectin-9), and PVR (CD155) were positively correlated with the expression of multiple m6A regulators, especially YTHDF2, YTHDF3, LRPPRC, METTL3, RBM15B, FTO, and ALKBH5 (Supplementary Figures 11A, B).
