The results showed that RAB42 overexpression is significantly correlated with that of partial immunosuppressive genes (C10orfs54, CD274, IDOI, HAVCR2, IL10, SLAMF7, CD276, TGFB1) and immunostimulatory genes (TNFRSF14, TLR4, TNFSF4, CD40LG, CD27, ICOS, PRF1, GZMA, CCL5, IFNG, BTN3A1, BTN3A2, CXCL10, CXCL9, IL2RA, CD80, TNFRRSF9, ITGB2, CD28, ICAM1, ENTPD1, CD40, TNFRSF4) across various cancer types. Here, CD274 is linked to cancer.
