Parathyroid hormone messenger ribonucleic acid: effects of calcium on cellular regulation in vitro.


The effects of changes in the concentration of extracellular calcium the principal regulatory of PTH secretion, on the cellular levels of the mRNA encoding prepro-PTH, a precursor of PTH, were studied in bovine parathyroid slices in vitro using a sensitive radiodensitometric cDNA hybridization assay and mRNA translation in a wheat germ cell-free system… (More)
