The effect of nutritional status on IGF-I mRNA expression in the liver and brain of juvenile
barramundi (Lates calcarifer) was investigated. Fish were either fed a satiety ration (SAT) or …

The in vivo actions of human and fish insulin-like growth factor (IGF)-I have been compared
to extend the understanding of the metabolism of IGFs in fish and to identify potential …

In salmonids, nutritional insufficiency leads to retarded growth and reduced hepatic GH
receptors, but increased circulating GH levels. To understand the endocrine mechanism …

Nutritional regulation of insulin-like growth factor-I (IGF-I) mRNA was assessed in liver of
gilthead sea bream (Sparus aurata). As in mammals, starvation lowered the IGF-I mRNA …

Insulin-like growth factors (IGFs) I and II (IGF-I and IGF-II) play important roles in fish growth
and development. The present study was aimed at isolating cDNAs encoding both IGF-I and …

In rodents, the expression of insulin-like growth factor II (IGF-II) is higher than that of insulin-
like growth factor I (IGF-I) during fetal life while the reverse is true after birth. We wanted to …

In spite of the importance of IGF-I for growth and development, knowledge about regulation
of its production in submammalian species is rather limited. In order to create a tool for …

The effects of fasting on insulin-like growth factor (IGF)-I, IGF-II, and IGF-binding protein
(IGFBPs) mRNA in channel catfish were examined. Fed control fish (Fed) were compared to …

The effects of prolonged nutrient restriction (fasting) and subsequent restoration (re-feeding)
on the growth hormone (GH)/insulin-like growth factor (IGF) axis were investigated in the …

Antisera to mammalian IGFs cross-react with several fish species, suggesting a long
phylogenetic distribution of IGF-I-immunoreacitivity (IGF-I-IR) was studied at various larval …
