ABSTRACT
Both human and salmon calcitonins markedly inhibit the TRH-stimulated rise in intracellular [Ca2+] in GH3 cells. Calcitonin also inhibits prolactin release from these cells. Both [Ala] salmon calcitonin and salmon calcitonin (1-23) peptide amide also inhibit this rise in [Ca2+] and also inhibit TRH-stimulated prolactin release from GH3 cells as well as from primary pituitary cell cultures. It is likely that calcitonin inhibits prolactin release in the pituitary by decreasing the extent of the rise of intracellular calcium concentration. Neither an intact disulfide bond at the amino terminus nor residues 24-32 of the carboxyl terminus of salmon calcitonin are required for this inhibition.
