Philip Zeitler et al.
Endocrine, 18(1), 85-90 (2002-08-09)
GHRH, in addition to stimulating the release of growth hormone (GH) from the pituitary, is a trophic factor for pituitary somatotrophs. Growth hormone-releasing hormone is also expressed in the gonads, gastrointestinal tract, pancreas, thymus, and lymphocytes, as well as in
E F Adams et al.
Pituitary, 1(1), 7-12 (2000-11-18)
Several earlier studies have shown that some human pituitary GH-secreting somatotrophinomas are able to synthesise and release hypothalamic GHRH and it has been proposed that a positive autocrine feedback loop involving this tumor-derived GHRH may participate in tumorigenesis. We have

European journal of endocrinology, 134(1), 67-72 (1996-01-01)
The effect of GHRH-antagonist [(N-Ac-Tyr1, D-Arg2) GRF-(1-29)-NH2] on plasma GH morning and evening secretion was evaluated in 14 normal subjects (10 males, 4 females, aged 19-25 years). Plasma GH was determined using a high sensitivity IRMA kit (detection limit, 0.006

The efficacy and potency of 14 GH-releasing factor (GRF) analogs, substituted in position 1 to 7, on adenylate cyclase activation in crude homogenates from rat anterior pituitary were related to those of human pancreatic GRF(1-29)-amide and vasoactive intestinal peptide. Among

A temporal association between non-rapid eye movement (NREM) sleep stages 3 and 4 and nocturnal augmentation of GH release was found long ago, yet the precise mechanism for this association has not been identified. It has been shown, however that
