The metabolic hormones, growth hormone (GH) and insulin-like growth factor (IGF)-I, together with IGF binding proteins (IGFBP), have been well studied in domestic species and are the primary components of the somatotropic axis. This hormone axis is responsive to nutrient intake, associated with growth rate, and accretion of protein and adipose. However, this relationship has not been evaluated ...

Specific binding of IGF-binding protein (IGFBP)-3 was shown to be present in the isolated, beating rat heart. The uptake of perfused (125)I-labeled IGF-I in the beating heart was decreased to 9% by blocking IGF-I binding sites with the IGF-I analog Long R(3) (LR(3)) IGF-I. When LR(3) was perfused with complexes of (125)I-IGF-I. IGFBP-3, uptake of (125)I-IGF-I was decreased to 41%, which was sig...

The purpose of this study was to measure serum levels insulin-like growth factor-binding protein (IGFBP7), Insulin-like Growth Factor 1 (IGF-1), Hormone (GH), Interleukin 6 (IL-6) and insulin in acromegaly patients healthy controls. group had 60 patients, while the population 30 people who never before. concentration IGFBP7, IGF-1, GH, IL-6, were determined. results present indicate that IGFBP7...

Expression of insulin-like growth factor (IGF) I and its type I receptor is increased in the adult rat lung exposed to 85% O2. We hypothesized that there would be a parallel up- and downregulation of growth-stimulating and growth-inhibiting IGF binding proteins (IGFBPs), respectively. The normal adult rat lung expresses mRNAs for IGFBP-2, -3, -4, -5, and -6 but not for IGFBP-1. O2 exposure for ...
