TIGIT and testicular germ cell tumor: Additionally, UPF3B expression was positively correlated with most immunoinhibitors, including TGFBR1, IL10RB, CD160, CD274, TIGIT and PDCD1 in UVM, OV, KIHC, and LIHC, but negatively associated with the expression of majority genes in STAD and Testicular Germ Cell Tumors (TGCT) (Fig 8C).
