Abstract
Acyl-CoA synthetase 4 (ACS4) is an arachidonate-preferring enzyme abundant in steroidogenic tissues. We demonstrate that ACS4 expression in steroidogenic tissues in vivo is induced by adrenocorticotropic hormone (ACTH) and suppressed by glucocorticoid. ACTH also induced ACS4 protein but not its mRNA in Y1 adrenocortical tumor cells, whereas both ACS4 mRNA and protein were increased by dibutyryl cAMP (db-cAMP) and forskolin. Furthermore, the levels of ACS4 mRNA and protein in Y1 cells were induced by arachidonate. These data suggest that ACS4 expression in steroidogenic cells is regulated in coordination with induced steroidogenesis and arachidonate released by cholesterol ester hydrolase.
