The analysis of serum TRAIL and IL-10 levels from AG PCa and BPH or indolent PCa patients, as well as diagnostic scores of tPSA and PHI, were demonstrated in scatterplots (Figure 1B), which presented a statistical significance between BPH/indolent PCa and AG PCa patients, though there was no significant correlation between PHI scores and concentrations of cytokines TRAIL and IL-10, respectively (Figure 1C). The gene discussed is IL10; the disease is benign prostatic hyperplasia.
