► Interleukin-6 is a multifunctional cytokine which regulates growth of prostate cancer. ► Stimulation of androgen receptor activity by interleukin-6 may enhance or inhibit proliferation. ► Interleukin-6 inhibits apoptosis in several prostate cancer cell lines. ► Suppressor of cytokine signalling-3 is expressed in prostate cancer. ► Antibody CNTO 328 (Anti IL-6) was tested in preclinical research and clinical trials. Several cytokines are involved in regulation of cellular events in prostate cancer. Interleukin-6 (IL-6) was frequently investigated in prostate cancer models because of its increased expression in cancer tissue at early stages of the disease. In patients with metastatic prostate cancer, it is well-known that IL-6 levels increase in serum. High levels of IL-6 were measured in the supernatants of cells which do not respond to androgenic stimulation. IL-6 expression in prostate cancer increases due to enhanced expression of transforming growth factor-beta, and members of the activating protein-1 complex, and loss of the retinoblastoma tumour suppressor. IL-6 activation of androgen receptor (AR) may contribute to progression of a subgroup of prostate cancers. Results obtained with two prostate cancer cell lines, LNCaP and MDA PCa 2b, indicate that IL-6 activation of AR may cause either stimulatory or inhibitory responses on proliferation. Interestingly, prolonged treatment with IL-6 led to establishment of an IL-6 autocrine loop, suppressed signal transducer and activator of transcription (STAT)3 activation, and increased mitogen-activated protein kinase phosphorylation. In several cell lines IL-6 acts as a survival molecule through activation of the signalling pathway of phosphotidylinositol 3-kinase. Expression of suppressors of cytokine signalling (SOCS) has been studied in prostate cancer. SOCS-3 prevents phosphorylation of STAT3 and is an important anti-apoptotic factor in AR-negative prostate cancer cells. Experimental therapy against IL-6 in prostate cancer is based on the use of the monoclonal antibody siltuximab which may be used for personalised therapy coming in the future.
