However, whether GC affects the development of Leydig cells is unclear. The goal of the present study is to investigate the effects of GC on steroidogenesis of rat progenitor Leydig cells (PLCs) in vitro. Dexamethasone (DEX) inhibited androsterone (AO) production in PLCs. The GR antagonist RU38486 reversed the DEX\u2010induced inhibition of AO, whereas the mineralocorticoid receptor antagonist RU28318 did not. RU38486 also reversed DEX\u2010induced reductions in steady\u2010state mRNA levels of steroidogenic acute regulatory protein (\n                    <jats:italic>Star<\/jats:italic>\n                    ) and 3\u03b2\u2010hydroxysteroid dehydrogenase 1 (\n                    <jats:italic>Hsd3b1<\/jats:italic>\n                    ). Steroidogenic acute regulatory protein (StAR) protein expression and 3\u03b2\u2010hydroxysteroid dehydrogenase (3\u03b2HSD) enzyme activity were affected similarly. These results show that GCs inhibit steroidogenesis of PLCs by suppression of StAR and 3\u03b2HSD via a GR\u2010mediated mechanism.\n
