Figure 2: Comparison of the PSA, PSMA (a), Raf-1, MEK-1, ERK-1, ERK-2 (b), NF-κB p65, NF-κB p50 (c), p-Akt (T308) and p-Akt (S473) (d), expression among (PSA+, PSMA+) profile according to groups: PC patients with positive immunoreactions to RKIP and PC patients with negative immunoreactions to RKIP. Values denoted by different superscripts are significantly different from each other. Those values sharing the same superscript are not statistically different from each other. Statistical analysis refers to each antibody separately. Significance was determined at .
