Effect of prostaglandin E 1 on certain renal actions of parathyroid hormone. 1972

Parathyroid hormone increased basal adenyl cyclase activity and that increase was inhibited by prostaglandin E(1) (PGE(1)). Tissue cyclic 3',5'-adenosine monophosphate (cyclic AMP) concentrations were increased by parathyroid hormone and that increase was likewise inhibited by PGE(1). Both parathyroid hormone and dibutyryl cyclic AMP increased (32)P incorporation into renal cortical phospholipids. PGE(1) diminished the effect of parathyroid hormone but not dibutyryl cyclic AMP to influence that parameter. PGE(1) likewise modulated the effect of parathyroid hormone but not dibutyryl cyclic AMP to decrease fractional phosphate reabsorption by the renal tubule. It is suggested that PGE(1) inhibits the effect of parathyroid hormone by decreasing its effect on adenyl cyclase. Such interaction may be important in modulating the intracellular action of parathyroid hormone on kidney cortex.

D010281 Parathyroid Hormone A polypeptide hormone (84 amino acid residues) secreted by the PARATHYROID GLANDS which performs the essential role of maintaining intracellular CALCIUM levels in the body. Parathyroid hormone increases intracellular calcium by promoting the release of CALCIUM from BONE, increases the intestinal absorption of calcium, increases the renal tubular reabsorption of calcium, and increases the renal excretion of phosphates.
