5alpha-Androstane-3beta,17beta-diol | inhibits hydroxylation of dehydroepiandrosterone by approximately 60-70% when both steroids are present at equimolar concentrations. A 10fold higher concentration of 5alpha-androstane-3beta,17beta-diol than of dehydroepiandrosterone in the incubation mixture results in the suppression of dehydroepiandrosterone hydroxylation by 80%. In HEK293 cells, the suppressive effect of 5alpha-androstane-3beta,17beta-diol on dehydroepiandrosterone metabolism is statistically significant also at a 10fold lower concentration of 5alpha-androstane-3beta,17beta-diol than of dehydroepiandrosterone in the incubation mixture | Homo sapiens | |
