1. Parathyroid hormone-related peptide (PTHrP), originally isolated from human malignant tumors, is present in a variety of normal mammalian tissues, including the brain. 2. The expression and translation of the PTHrP gene within the rat hypothalamus was demonstrated in this study by the specific hybridization of a 1.8 kb mRNA product with a PTHrP cDNA probe and by the crossreactivity of rat hypothalamic extracts in a PTHrP radioimmunoassay. 3. These results suggest roles for PTHrP in neural or hypophysiotropic regulation.
