In patients with high-grade and locally advanced PC, those with IL-30−/−tumors, showed distinct intra-tumoral cytotoxic granule-associated RNA binding protein (TIA-1)+CD4+Tlymphocyte infiltrate, rare Foxp3+Tregs and a lower biochemical recurrence rate compared to patients with IL-30+/+tumors in which IL-30 is expressed in both tumor cells and infiltrating leukocytes. The gene discussed is TIA1; the disease is neoplasm.
