Diurnal rhythms in pineal N-acetyltransferase and hippocampal norepinephrine: effects of water deprivation, blinding and hypothalamic lesions.

abstract：BACKGROUND:Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) express insulin-like growth factor (IGF)-related factors [IGF1, IGF2; insulin receptor (IR)-A, IR-B; IGF-binding protein (IGFBP) 1-3] as well as somatostatin (SSTRs) and dopamine D2 receptors (D2Rs). OBJECTIVES:To (1) compare mRNA expression of IGF-rel...
