Survival analysis of DEGs in grade II-IV glioma in the TCGA dataset. Survival analysis of DEGs in the TCGA dataset revealed that the SST (A), SSTR1 (B), SHANK2 (C), HTR5A (D), HTR1A (E), HRH3 (F), GLP1R (G), GABBR2 (H), CHGA (J), and CCK (K) genes are good prognostic markers for glioma. While the high expression of CXCL10 (I) and ANXA1 (L) are correlated with poor outcome.
