Furthermore, we detected the positive correlation between GAS2L3 gene expression and the infiltration level of resident memory T cell (R = 0.5), effector memory T cell (R = 0.36), effector T cell (R = 0.37), effector Treg T cell (R = 0.25), exhausted T cell (R = 0.3), and Th1‐like T cell (R = 0.35), in the TCGA‐LGG (all p < 0.0001), but not TCGA‐GBM project (Figure S10). The gene discussed is GAS2L3; the disease is glioblastoma.
