We also observed that tumor gp96 expression correlated significantly with single PD-1+ immune cell infiltrative levels within the tumor microenvironment (Figures 3(g)–3(i), Supplemental Figures 3(g)–3(i), Supplemental Figures 4(g)–4(i)), suggesting a possible interplay between gp96 expression and PD-1 upregulation. The gene discussed is HSP90B1; the disease is neoplasm.
