Interactions of Calcium and Cyclic AMP Signaling Pathways Regulating Steroidogenesis in Primary Cultured Theca and Granulosa Cells of Atlantic Croaker
Fish Physiology and Biochemistry
The function of adenylyl cyclase (AC)-dependent and calcium (Ca2+)-dependent signal transduction pathways in mediating gonadotropin-stimulated testosterone (T) synthesis in croaker follicular cells was investigated. Both pathways are critical regulators of steroidogenesis in these cells. Stimulation of steroidogenesis by modulators of AC-dependent cell signaling is partially dependent on the presence of extracellular Ca2+, although AC function does not appear to be mediated by the Ca2+ pathway in croaker follicular cells.
