Fisiologia do eixo GH-sistema IGF
(Sociedade Brasileira de Endocrinologia e Metabologia, 2008)
O crescimento, principal característica da infância e da adolescência, apresenta padrão semelhante na maioria dos indivíduos. A herança genética e os componentes do eixo GH-IGF são os fatores que diretamente influenciam ...
Expression and protein content of IGF-I and IGF-I receptor in placentas from small, adequate and large for gestational age newborns
In humans, a direct relationship between IGF-I cord blood levels and birth weight has been demonstrated. To determine the placental IGF-I, IGF-II and IGF-IR mRNA and protein contents in full-term pregnancies from appropriate ...
Hepatic mRNA expression and plasma levels of insulin-like growth factor-I (IGF-I) in broiler chickens selected for different growth rates
(Sociedade Brasileira de Genética, 2004-01-01)
The hepatic expression and plasma concentrations of IGF-I were investigated in three broiler chicken strains selected for different growth rates (HP-Hubbard-Pettersen, a fast growing strain; NN-Naked-neck, a strain with ...
Immunolocalization of the insulin like growth factor-1 (IGF-1) and IGF-1 receptor (IGF-1R) in the ovary of the bitch
Impact of hypoxia on IGF-I, IGF-II, IGFBP-3, ALS and IGFBP-1 regulation and on IGF1R gene expression in children
(CHURCHILL LIVINGSTONEEDINBURGH, 2012)
Hypoxia is one of many factors involved in the regulation of the IGF system. However, no information is available regarding the regulation of the IGF system by acute hypoxia in humans. Objective: The aim of this study was ...
Igf2 And Igf1r In Pediatric Adrenocortical Tumors: Roles In Metastasis And Steroidogenesis
(BIOSCIENTIFICA LTDBRISTOL, 2016)
Insulin-like growth factors (IGFs) and IGF binding proteins-1, -2, and -3 in newborn serum: Relationships to fetoplacental growth at term
(Elsevier Ireland Ltd, 1996)
Cord sera were obtained from term, Chilean newborns exhibiting various patterns of intrauterine growth and assayed for IGF-1, IGF-2, IGFBP-1, IGFBP-2, and IGFBP-3 by specific radioimmunoassays (RIA). Serum levels of each ...
Fsh Stimulates Spermatogonial Proliferation and Differentiation in Zebrafish via Igf3
(Endocrine Soc, 2015-10-01)
Growth factors modulate germ line stem cell self-renewal and differentiation behavior. We investigate the effects of Igf3, a fish-specific member of the igf family. Fsh increased in a steroid-independent manner the number ...
Feed restriction and insulin-like growth factor-I (IGF-I) affect the oocyte maturation in matrinxã Brycon amazonicus
Summary The feeding and nutrition of breeders are crucial aspects in the reproductive process. During the maturation period, metabolic changes occur aiming at mobilizing energy for growth and follicular development. The ...
