B7H4 and TIM3 mRNA, which are encoded by the Vtcn1 and Havcr2 genes, respectively, and like PDL1, encode immune checkpoint receptors that are HIF regulated (51, 52) and associated with patient mortality in HCC (53), showed hypoxia-induced expression in vehicle-treated but not in 32-134D–treated cells (P < 0.05; Figure 3B). The gene discussed is CD274; the disease is hepatocellular carcinoma.
