Steroidogenesis in immature chicken ovary. Hormonal stimulation of adenylyl cyclase system by luteinizing hormone and β-adrenergic agonists

The presence of a hormonally responsive adenylyl cyclase in the immature chicken ovary was investigated. We found that there was a highly significant difference (P< 0. 05) between basal and LH and catecholamine activatable activities. In addition, the basal activity was stimulated by NaF, forskol...
