Eight proteins (A2M, AHSG, C3, FGA, FGG, HPX, ITIH4, SERPING1) from our dataset are included in Acute Phase Response Signaling pathway from PCa vs. BPH comparison and 11 proteins (AMBP, APOA1, APOH, AHSG, C3, C4A, F2, FGA, FGG, HPX, ITIH4,) from PCa vs. BC comparison. This evidence concerns the gene HPX and benign prostatic hyperplasia.
