CARM1 and testicular germ cell tumor: The results of the top three tumors with the highest correlation coefficient have been shown in Fig. 9, which reveal that CARM1 expression is significantly negatively correlated with immune scores in LUSC, SARC, testicular germ cell tumors (TGCT), indicating that the content of immune cells decreases while the level of CARM1 expression escalates (Fig. 9a).
