Role of SOCS3 evaluated by immunohistochemical analysis in a cohort of patients affected by prostate cancer: preliminary results

Chronic inflammation may play a role in prostate carcinogenesis. Molecular alterations of the Suppressor of Cytokine Signaling (SOCS)-3 can contribute to explain the pleiotropic role of interleukin (IL)-6 in this type of cancer. Recently, the methylation of SOCS3 gene has been demonstrated to cause the non-expression of the protein, being involved in the pathogenesis of prostate cancer (PC) and identifying a subset of aggressive tumors. We evaluated the expression of SOCS3 protein in patients (pt) with bioptically-diagnosed PC by immunohistochemical analysis, which is easier to perform, cheaper and more reproducible compared to DNA analysis.
