Bi-dimensional proteome maps of serum samples from PCa without (A) and with inflammation (B), and BPH in absence (C) and presence of inflammation (D). Proteins were resolved by IEF over the pH range 4–7, followed by 8-16% gradient gel and visualized by Silver staining. Significant differentially expressed proteins are marked with alphanumeric labels, corresponding to those listed in Tables 5, 6 and 7. Yellow tags indicate the overlapped proteins detected in presence of inflammation in both PCa (B) and BPH (D) conditions. Some of these proteins were also revealed in PCa in absence of inflammation (A, third comparison). Additionally, in this latter situation, green labels represent proteins not previously identified in the first and second comparisons, namely in presence of inflammation.
