[Role of calcium in TRH-induced secretion of alpha-MSH in the frog].
In amphibians, alpha-MSH secretion is stimulated by thyrotropin-releasing hormone (TRH). In the present study we show that extracellular calcium influences directly the spontaneous secretion of alpha-MSH and that it participates in the mechanism of action of TRH on frog melanotrophs.
