IGF-I, marqueur nutritionnel

Nutrition Clinique et Métabolisme, 1996
Resume De nombreux effets anaboliques de l'hormone de croissance (GH) sont induits par l' Insulin-like Growth Factor-1 (IGF-I), polypeptide mitogenique presentant des similitudes structurales avec l'insuline. Les concentrations plasmatiques de l'IGF-I varient selon l'etat nutritionnel, la situation metabolique et les pathologies presentes.

Intraovarian regulation: the IGF-I example

Reproduction, Fertility and Development, 1992
A large body of information now supports the existence of an intraovarian system of insulin-like growth factors (IGFs) replete with ligands, receptors, and binding proteins. The intraovarian IGF system is most likely concerned with the amplification of gonadotrophin hormonal action, other potential regulatory roles remaining speculative at this time ...

Overview of the IGF-I System

Hormone Research, 2006
• The IGF system is the major mediator of both intra-uterine and postnatal growth. • The IGF-I receptor appears to mediate the growth-promoting effects of both IGF-I and IGF-II. • The role of IGF binding proteins in mediating the growth-promoting actions of the IGFs is complex and remains incompletely understood.

Molecular Mechanisms of IGF-I Deficiency

Hormone Research, 2006
• A molecular basis for many forms of Primary IGFD has now been identified. • Disorders of the GH receptor can have low levels of GHBP (as in most defects of the extracellular domain of the GH receptor), or normal levels of GHBP (as in defects of the transmembrane and intracellular domains) • A growth phenotype similar to that seen in defects of the GH

Age related IGF-I changes and IGF-I generation in thalassemia major.

Pediatric endocrinology reviews : PER, 2011
We measured serum concentrations of insulin like growth factor-I (IGF-I) in 20 thalassemic males with short stature (height SDS

IGF-I Physiology and Breast Cancer

1998
Recent studies imply that IGF-I levels vary greatly between normal women, and that premenopausal breast cancer risk is increased among women with higher IGF-I levels. It is known that tamoxifen lowers IGF-I levels, but further research is needed to determine whether antiestrogens will be of particular value in risk reduction for women with high IGF-I ...

GH-IGF-I deficit

2010
La sindrome da difetto di GH (GHD) nell’adulto è un entità clinica riconosciuta solo negli ultimi decenni, quando sono stati dimostrati gli importanti effetti metabolici del GH nell’arco di tutta la vita. Il GH infatti possiede azioni anaboliche sull’osso, sul muscolo scheletrico e cardiaco, mediate prevalentemente dall’IGF-I, promuove sintesi ...
