The peptide hormone atrial natriuretic factor (ANF) exerts its effect in a receptor-mediated fashion and the membrane-bound form of guanylate cyclase represents a biologically active ANF receptor;...
Direct and indirect effects of murine interleukin-2, gamma interferon, and tumor necrosis factor on testosterone synthesis in mouse Leydig cells
murine interleukin-2 gamma interferon tumor necrosis factor testosterone synthesis
2009/2/11
It was recently observed that treatment of patients with a high dosage of human interleukin (IL-2) resulted in suppression of plasma concentrations of testosterone. A murine model was developed to a...

Whether cytokines present in human peritoneal fluid reduce sperm motility, and thus contribute to infertility, is investigated. The human recombinant cytokines, tumor necrosis factor-alpha, interl...
Rat tumor Leydig cells as a test system for the study of Sertoli cell factors that stimulate steroidogenesis
Insulin-like growth factor I (IGF-l) paracrine factors
2009/2/7
Transplantable rat Leydig cell tumor H-540 was used to study the interactions between Leydig and Sertoli cells. These tumor cells maintain their steroidogenic capacity when cultured. Their responsiv...
