FAIM2 and glioblastoma: Interestingly, in our results, almost all immune checkpoints were inversely correlated with FAIM2 expression in COAD, LGG, and GBM, but the complete opposite results were observed in other tumors, which suggests that FAIM2 may be a potential immunotherapeutic target for COAD, LGG, and GBM, while in other tumors, FAIM2 is positively correlated with checkpoint expression which might indicate that patients with high FAIM2 expression are more sensitive to immune checkpoint blockade therapy.
