GSTO2 and colon adenocarcinoma: The results revealed that the expression level of GSTO2 was significantly negatively correlated with BTLA, CTLA4, NRP1, IDO2, CD276, ADORA2A, LAIR1, CD40, TNFRSF4, and TNFSF15 expression in COAD (Figures 10(a)–10(j)), while GSTO2 expression in TIMER2.0 was positively correlated with TNFSF9 and ABCA12 expression in COAD (Figures 10(k)-10(l)).
