Growth hormone response to growth hormone-releasing peptide-2 in growth hormone-deficient Little mice
OBJECTIVE To investigate a possible direct, growth hormone-releasing, hormone-independent action of a growth hormone secretagogue, GHRP-2, in pituitary somatotroph cells in the presence of inactive growth hormone-releasing hormone receptors. MATERIALS AND METHODS The responses of serum growth hormone to acutely injected growth hormone-releasing P-2 in lit/lit mice, which represent a model of ...
متن کاملPredicting bull growth performance and carcass composition from growth hormone response to growth hormone-releasing hormone.
Development of practical, physiologically based methods that provide an early, yet accurate, evaluation of a bull's genetic merit could benefit the beef industry. The use of GH response to a single, acute dose of GHRH was evaluated as a predictor of future growth performance and carcass characteristics of weanling bulls. Fifty-six Angus bulls averaging 229 d (SD = 27) of age were administered t...
متن کاملLow growth hormone response to growth hormone-releasing hormone in child depression.
BACKGROUND This study examined growth hormone (GH) response to growth hormone-releasing hormone (GHRH) in a large sample of depressed children compared with normal control children. Within-subject comparisons were also performed in control subjects to examine test-retest reliability and in depressed children comparing episode versus clinical recovery. METHODS The sample included depressed chi...
متن کاملGrowth hormone response to growth hormone-releasing hormone in beef cows divergently selected for milk production.
In dairy cattle, increased circulating growth hormone has been associated with selection for greater milk yield. This study tested the hypothesis that beef cows divergently selected for milk production would have differing GH responses to a challenge dose of GHRH. Growth hormone response to a challenge of GHRH was measured in 36 Angus-sired cows ranging from 6 to 10 yr of age. The cows were cla...
متن کاملChronopharmacological effects of growth hormone on the executive function and oxidative stress response in rats
Objective(s): to investigate the chronopharmacological effects of growth hormone on executive function and the oxidative stress response in rats. Materials and Methods: Fifty male Wistar rats (36-40 weeks old) had ad libitum access to water and food and were separated into four groups: diurnal control, nocturnal control, diurnal GH-treated, and nocturnal GH-treated animals. Levels of Cu, Zn sup...
