The aim of the present work was to study the immune profiling of prostate epithelial cells by the expression of ASK-1/p38 and Raf-1/ERK MAP Kinases signaling pathways mediated by TRAF-6. Immunohistochemical and Western blot analyses for TRAF-6, ASK-1, MEK-6, p38, Raf-1, MEK-1, ERK-1, ERK-2 and PSA were carried out in 5 samples of normal prostate gland, 24 samples of BPH and 19 samples of PC. Immunoreaction to TRAF-6 was found in the cytoplasm of epithelial cells of BPH and tumor cells of PC samples. For patients with the profile (TRAF-6+), optical densities revealed a weak immunoexpression of ASK-1 in PC compared to BPH patients. Whereas, immunoexpression to Raf-1 was higher in PC than in BPH. According to the expression of ASK-1 and Raf-1, two main profiles were identified: (TRAF-6+, ASK-1+, Raf-1+) and (TRAF-6+, ASK-1+, RAF-1-) in both BPH and PC. In addition, ASK-1/p38 axis expression was increased in BPH. Raf-1/ERK signaling pathway was increased in PC samples. On the other hand, representing of individual signaling protein expression enclosing each of p38 and ERK MAP Kinases according to TRAF-6+ showed a qualitative behavior of ASK61/p38 and Raf-1/ERK signaling pathways and a dynamic expression of PSA associated with immune and inflammatory process. These findings suggest that prostate epithelial cell could able an immune and inflammatory setting.
