1	The Effects of Serum from Obese Patients and Adipocyte-derived Cytokines on Growth of Prostate Cancer Cells In Vitro Mora, Benjamin 03 July 2014 (has links) Obesity has been related to a greater incidence of more aggressive, advanced stage prostate cancer. It is expected that serum adipokines related to obesity will promote a more aggressive phenotype in PC cells in vitro. Patient serum (n = 80) was obtained for analysis and divided into four patient groups based on obesity and prostate cancer status. Characteristics of serum-treated PC cells in vitro were measured. In a separate set of analyses, LNCaP and PC3 cells were treated with adiponectin and resistin in vitro, and cell characteristics were analyzed. Serum from obese PC patients induces greater amounts of cell migration and lower amounts of cell proliferation and invasion in vitro. Exogenous treatment of adiponectin on PC cells in vitro does not affect cell migration or invasion. However, adiponectin modulates cytosolic protein levels of soluble β-catenin and GSK-3β, indicating that its mechanism of action may be through the Wnt signalling pathway. oncology urology cancer prostate obesity adipokines prostate cancer cytokines adipocytes adiponectin resistin fat cells tumor malignancy neoplasm body mass index in vitro wnt proliferation migration invasion LNCaP PC3 overweight fat adiposity beta-catenin glycogen synthase kinase-3beta 0992
