title: Demonstration of a neuropeptide Y-like immunoreactivity in human phaeochromocytoma extracts.
abstract: Using a porcine neuropeptide Y directed radioimmunoassay it was shown that acid extracts of human phaeochromocytoma tumour tissue contained a neuropeptide Y-like peptide. Further fractionation and purification of this immunoreactivity showed that this human neuropeptide Y-like immunoreactivity was closely similar in molecular size and separation characteristics to porcine neuropeptide Y. The possible contribution of neuropeptide Y to the hypertension characterizing human phaeochromocytoma is discussed.
