1 TNF and IL-1 both inhibit cAMP-stimulated testosterone production as well as mRNA and protein levels of cholesterol side chain cleavage enzyme (P450scc) and 17 alpha-hydroxylase/C17,20 lyase (P450c17) in mouse Leydig cells. Testosterone interleukin 1 complex Mus musculus
2 In the present study, we tested the effects of TNF and IL-1 on basal testosterone production and 8-Br-cAMP-stimulated 3 beta-hydroxysteroid dehydrogenase/delta 5-->delta 4 isomerase (3 beta HSD) expression in Leydig cells. Testosterone interleukin 1 complex Mus musculus
3 These results demonstrate that TNF and IL-1 have different effects on basal steroidogenesis in Leydig cells and suggest that TNF-mediated inhibition of basal testosterone production may be owing to the inhibition of basal 3 beta-HSD expression in Leydig cells. Testosterone interleukin 1 complex Mus musculus
