Title: Neuropeptide Y in phaeochromocytomas and ganglioneuroblastomas. Author: Adrian TE, Allen JM, Terenghi G, Bacarese-Hamilton AJ, Brown MJ, Polak JM, Bloom SR. Journal: Lancet; 1983 Sep 03; 2(8349):540-2. PubMed ID: 6136694. Abstract: Tumour tissue from nineteen patients with phaeochromocytomas and nine with ganglioneuroblastomas contained large numbers of neuropeptide Y (NPY) producing cells and extracts of these tumours had very high concentrations of immunoreactive NPY. Plasma NPY concentrations were also raised, averaging 460 pmol/l in patients with tumours of the sympathetic chain and 55 pmol/l in healthy controls. Since plasma NPY is straightforward to measure and relatively stable, its estimation may prove helpful as a screening tests for phaeochromocytoma.[Abstract] [Full Text] [Related] [New Search]
