%0 Journal Article %T Increased IL-17 and IL-6 Transcripts in Peripheral Blood Mononuclear Cells: Implication for a Robust Proinflammatory Response in Early Stages of Breast Cancer %A Mansooreh Jaberipour %A Rasoul Baharlou %A Ahmad Hosseini %A Abdolrasoul Talei %J Middle East Journal of Cancer %D 2011 %I Shiraz University of Medical Sciences %X Background: Several recent studies demonstrated that transforming growth factor beta (TGF-¦Â), by stimulating T regulatory cells, and interleukins 6 and 17 (IL-6, IL-17), by inducing inflammatory reactions, may be critical factors in cancer pathogenesis. Methods: We used quantitative real-time polymerase chain reaction assays to quantify the expression of IL-17, IL-6 and TGF-¦Â mRNA in peripheral blood mononuclear cells and lymphocytes from draining lymph nodes of 60 women with breast cancer. The results were compared according to the patients¡¯ clinical or pathological status. Results: Higher amounts of IL-17 and IL-6 mRNA, but not TGF-¦Â transcripts, were found in patients compared to controls. There were no significant differences between patients with negative or positive nodes or with different histological grades or stages of disease. Conclusion: Most women in this analysis had stage I or II disease. We thus conclude that IL-17, a prominent proinflammatory cytokine, may play an important role in recruiting and infiltrating antitumor immune responses in early stages of breast cancer. %K Breast cancer %K Interleukin-6 %K Interleukin-17 %K Transforming growth factor beta %U http://mejc.sums.ac.ir/index.php/mejc/article/view/44/117
