Insulin-like growth factor I and insulin-like growth factor binding protein 5 in Crohn's disease.
Insulin-like growth factor (IGF)-I and its binding protein IGF binding protein 5 (IGFBP-5) were highly expressed in inflamed and fibrotic intestine in experimental Crohn's disease. IGF-I induced proliferation and increased collagen synthesis by smooth muscle cells and fibroblasts/myofibroblasts in vitro. Here we studied IGF-I and IGFBP-5 in Crohn's disease tissue. Tissue was collected from pati...
متن کاملVertex balding, plasma insulin-like growth factor 1, and insulin-like growth factor binding protein 3.
BACKGROUND A recent report suggested that men with vertex balding have higher levels of plasma insulin-like growth factor 1 (IGF-1). The association of its major carrier protein, insulin-like growth factor binding protein 3 (IGFBP-3), with male pattern hair loss has not been examined. OBJECTIVE We evaluated the relations of plasma concentrations of IGF-1 and IGFBP-3 with vertex balding in mid...
متن کاملProtease-resistant form of insulin-like growth factor-binding protein 5 is an inhibitor of insulin-like growth factor-I actions on porcine smooth muscle cells in culture.
IGFs are pleiotrophic mitogens for porcine smooth muscle cells (pSMC) in culture. The effects of IGFs on cells are modulated by various insulin-like growth factor-binding proteins (IGFBP). IGFBP-5 is synthesized by pSMC and binds to the extracellular matrix. However, IGFBP-5 is also secreted into conditioned medium of cultured cells and is cleaved into fragments by a concomitantly produced prot...
متن کاملTransferrin is an insulin-like growth factor-binding protein-3 binding protein.
Insulin-like growth factor (IGF)-binding protein-3 (IGFBP-3) possesses both growth-inhibitory and -potentiating effects on cells that are independent of IGF action and are mediated through specific IGFBP-3 binding proteins/receptors located at the cell membrane, cytosol, or nuclear compartments and in the extracellular matrix. We have here characterized transferrin (Tf) as one of these IGFBP-3 ...
متن کاملEffects of Nerve Growth Factor, Insulin- Like Growth Factor-I and Collagen Gel on Peripheral Nerve Channel: Sensory, Functional and Regeneration Through Piezoelectric Electrophysiologicalal Study
Purpose: The limited availability of donor sites for nerve grafts continues to stimulate research toward finding suitable alternatives. Material and Methods: In the following study, the effects of direct administration of Nerve Growth Factor (NGF), Insulin - Like Growth Factor - I (IGF-I) , or / and collagen gel into Polyvinylidene Fluride (PVDF) gap was tested in a rat sciatic nerve model. A ...
