Ghrelin injection, either centrally or peripherally strongly stimulates feeding in human and rodents. In contrast, centrally injected ghrelin inhibits food intake in neonatal chickens. No information is available about the mechanism and its relations

In the chicken and other avian species, the secretion of GH is under a dual stimulatory and inhibitory control of hypothalamic hypophysiotropic factors. Additionally, the thyrotropin-releasing hormone (TRH), contrary to the mammalian situation, is al

The intracellular thyroid hormone (TH) availability is influenced by different metabolic pathways. Some of the changes in intracellular TH availability can be linked to changes in local deiodination and sulfation capacities. The secretion of the chic

Glucocorticoids as well as thyroid hormones are essential for normal brain development. Exogenous glucocorticoids stimulate 3,3',5-triiodothyronine (T(3)) availability in circulation of birds and similar effects have been observed in sheep. Chicken d

It is widely accepted that type II iodothyronine deiodinase (D2) is mostly present in the brain, where it maintains the homeostasis of thyroid hormone (TH) levels. Although intensive studies have been performed on activity and mRNA levels of the deio

Pit-1 is a pituitary-specific POU-domain DNA binding factor, which binds to and trans-activates promoters of growth hormone- (GH), prolactin- (PRL) and thyroid stimulating hormone beta- (TSHβ) encoding genes. Pit-1 has been identified in several mam

Iodothyronine deiodinase in vitro activity studies in the chicken showed the presence of type I and type III iodothyronine deiodinase activity in both liver and kidney. Due to the lack of a specific antiserum the cellular localization of the deiodina

Chicken ghrelin has recently been isolated as a hormone which stimulates growth hormone and corticosterone secretion in chicken. Ghrelin mediates these actions in mammals by binding to the growth hormone secretagogue receptor (GHS-R). In this study,

The presence of outer ring deiodinating (ORD) and inner ring deiodinating (IRD) activities was investigated in different tissues of Oreochromis niloticus (Nile tilapia), Clarias gariepinus (African catfish), Oncorhynchus mykiss (rainbow trout) and ha

Fasting and refeeding have considerable effects on thyroid hormone metabolism. In tilapia (Oreochromis niloticus), fasting results in lower plasma T3 and T4 concentrations when compared to the ad libitum fed animals. This is accompanied by a decrease
