Periprandial changes in growth hormone release in goldfish: role of somatostatin, ghrelin, and gastrin-releasing peptide

Abstract

Canosa, Luis Fabián, Suraj Unniappan, and Richard Ector Peter. Periprandial changes in growth hormone release in goldfish: role of somatostatin, ghrelin, and gastrin-releasing peptide.

Increased food intake in growth hormone-transgenic common carp (Cyprinus carpio L.) may be mediated by upregulating Agouti-related protein (AgRP)

“…These results are in concordance with the studies in goldfish, flounder, rainbow trout and salmons (Canosa et al, 2005;Fuentes et al, 2012;Gabillard et al, 2006;Pierce et al, 2005;Shimizu et al, 2009). Next, we observed high expression levels of serum GH in both fasted and fed TG common carp, while there is no significant difference between them ( Fig.…”

Effect of Chitosan Supplemented Diet on Survival, Growth, Feed Utilization, Body Composition & Histology of Sea Bass (Dicentrarchus labrax)

“…GH can influence skeletal and muscle growth via direct and indirect effects on protein, lipid and carbohydrate metabolism [35] and fulfill its function of growth promotion through improving the production of IGF-I. IGF-I can stimulate amino acid uptake and protein synthesis in muscles and can greatly reduce the rate of protein breakdown within muscle fibers [36]. The causes of this result are unclear and require further experimentation to solve.…”

Complex Rhythmicity of Growth Hormone Secretion in Humans

“…The role of feedings as the generators of GH "waves" during the daytime is unlikely, however, as there was no breakfast associated GH augmentation in our study either in men, or in women. Additionally, food associated GH release was shown to occur 2-3hrs postprandially [34,35] likely as a result of declining plasma glucose concentrations, whereas the daytime GH "waves" in both sexes emerged prior to scheduled food intake. Obviously, the best way to ascertain the effects of the feedings on GH rhythmicity would be to study a large sample of GH profiles obtained in fasting individuals.…”
