High levels of reactive oxygen species (ROS) present in human prostate epithelia are an important etiologic factor in prostate cancer (CaP) occurrence, recurrence, and progression. Androgen induces ROS production in the prostate by a yet unknown mechanism. Here, to the best of our knowledge, we report for the first time that androgen induces an overexpression of spermidine/spermine N1-acetyltra...
Polycystic ovary syndrome (PCOS) is a complex hormonal disorder characterized by reproductive, endocrine, and metabolic abnormalities. As the origins of PCOS remain unknown, mechanism-based treatments are not feasible and current management relies on treatment of symptoms. Hyperandrogenism is the most consistent PCOS characteristic; however, it is unclear whether androgen excess, which is treat...
PURPOSE Androgen deprivation therapy increases the risk of osteoporosis related fractures. This issue is of increasing importance in men with prostate cancer as increasingly more undergo androgen deprivation therapy and therapy is administered sooner following diagnosis. Data directly addressing the long-term fracture risk in men diagnosed with prostate cancer are limited. MATERIALS AND METHO...
Stimulation of a Shionogi carcinoma 115-derived cultured cell line (SC-3) with androgen resulted in secretion of heparin-binding growth factor. In this study, we analyzed cell-surfaced receptors for growth factors. Binding data of growth factors on intact SC-3 cells revealed the presence of low and high affinity receptors for epidermal growth factor (EGF), insulin, and fibroblast growth factor ...
Whether or not blood pressure (BP) and heart function of women with polycystic ovary syndrome (PCOS) are altered remains unclear, albeit subtle abnormalities in the regulation of BP observed in these women might suggest a mild masculinization of their cardiovascular system. To study the influence of obesity and androgen excess on BP and echocardiographic profiles of women with the syndrome, we ...
