Effects of zinc sulfate (ZnSO4) in diet on the growth performance and gene expression of Insulin-like growth factor-1 (IGF-1) and Ghrelin in goldfish (Carassius auratus)
The zinc element (Zn) is one of the micronutrients and an essential element of the body which has some deleterious and irreparable effects on growth in case of lack it. Thus, we aimed to assess IGF-1 in goldfish with Zn deficiency and to investigate the effect of Zn supplementation on these parameters. Goldfish (Carassius auratus) juvenile (3.5 g) were fed purified diets based on casein as ...
متن کاملInsulin-like growth factor 1 (IGF-1): a growth hormone.
AIM To contribute to the debate about whether growth hormone (GH) and insulin-like growth factor 1 (IGF-1) act independently on the growth process. METHODS To describe growth in human and animal models of isolated IGF-1 deficiency (IGHD), such as in Laron syndrome (LS; primary IGF-1 deficiency and GH resistance) and IGF-1 gene or GH receptor gene knockout (KO) mice. RESULTS Since the descri...
متن کاملIn vivo actions of insulin-like growth factor-I (IGF-I) on brain myelination: studies of IGF-I and IGF binding protein-1 (IGFBP-1) transgenic mice.
To study the effects and mechanisms of insulin-like growth factor I (IGF-I) on brain myelination in vivo, the morphology of myelinated axons and the expression of myelin specific protein genes have been examined in transgenic (Tg) mice that overexpress IGF-I and that those ectopically express IGF binding protein-1 (IGFBP-1), a protein that inhibits IGF-I actions when present in molar excess. Ou...
متن کاملInsulin-like growth factor 1 (IGF-1) receptors, IGF-1, and IGF-2 are expressed in primary human sarcomas.
A variety of bone and soft-tissue sarcoma cell lines have been shown to express receptors for insulin-like growth factor-1 (IGF-1) and to respond mitogenically to IGF-1 in vitro. We have recently demonstrated evidence of IGF dependency in murine MGH-OGS and RIF-1 sarcomas, which express relatively high and intermediate levels of IGF-1 receptors. Overexpression of IGF-1 receptors and/or IGF liga...
متن کاملAutocrine IGF-1 Action in Adipocytes Controls Systemic IGF-1 Concentrations and Growth
OBJECTIVE IGF-1 and the IGF-1 receptor (IGF-1R) have been implicated in the regulation of adipocyte differentiation and lipid accumulation in vitro. RESEARCH DESIGN AND METHODS To investigate the role of IGF-1 receptor in vivo, we have inactivated the Igf-1r gene in adipose tissue (IGF-1R(aP2Cre) mice) using conditional gene targeting strategies. RESULTS Conditional IGF-1R inactivation resu...
