The transcription of the insulinlike growth factor 1 (igf-1) gene generates three mRNA isoforms, namely IGF-1Ea, IGF-1Eb and IGF-1Ec (or MGF [mechano growth factor]). Herein, we analyzed the expression of IGF-1 isoforms in eutopic and ectopic endometrium (red lesions and endometriotic cysts) of women with endometriosis, and we characterized the actions of a synthetic MGF E-peptide on KLE cells....
The ability of insulin-like growth factor-1 (IGF-1) to regulate surface expression of the interferonreceptor 2 (IFNR2) transducing chain and activation of IFN– induced signal transducer and activator of transcription-1 (STAT-1) in human T cells was analyzed. We show that, especially in the absence of serum (which contains IGF-1), IGF-1 down-regulated surface expression of the IFNR2 chain and in...
The role of genetic inheritance in brain development has been well characterized, but little is known about the contributions of natural environmental stimuli, such as the effect of light-dark cycles, to brain development. In this study, we determined the role of light stimuli in neuronal cell migration to elucidate how environmental factors regulate brain development. We show that in early pos...
IGF-1 and IGF-2 are potent mitogens acting through the IGF-1 receptor (IGF-1R). The importance of the IGF system in neoplasia has been demonstrated in several models, and IGF-1 signaling has become a target for drug development. The drug candidate BI 836845 is a fully human IgG1 ligand-neutralizing antibody that cross-reacts with IGF-1 and IGF-2. It has been shown to reduce both IGF-1R phosphor...
Low levels of insulin-like growth factor-1 (IGF-1), an essential neurotrophic factor, have been associated with worse cognitive function in older adults. However, few studies have assessed the prospective association of serum IGF-1 with cognitive function. We aimed to determine the association between serum IGF-1 on concurrent and prospective cognitive function in a population sample of men age...
The insulin-like growth factor (IGF) is a complex system of peptide hormones (insulin-like growth factors of type 1 and 2, IGF-1 and IGF-2), cell surface receptors (insulin receptor, IR; insulin-like growth factor receptors of type 1 and 2, IGF-R1, IGF-R2) and circulating binding proteins (insulinlike growth factor binding proteins, IGF-BP 1-6). IGF-1 and -2 are mitogens that play a role in reg...
Insulin-like growth factor (IGF)-1 plays crucial roles in growth control and rearrangements of the cytoskeleton. IGF-1 binds to the IGF-1 receptor and thereby induces the autophosphorylation of this receptor at its tyrosine residues. The phosphorylation of the IGF-1 receptor is thought to initiate a cascade of events. Although various signaling molecules have been identified, they appear to int...
We analysed the glucocorticoid receptor (GR) regulation on the expression of insulin-like growth factor 1 (IGF-1), type I IGF receptor (IGF-1.R), IGF-binding protein 3 (IGFBP-3), urokinase-type plasminogen activator (uPA) and uPA receptor (uPA.R) mRNA in human KLE endometrial-like cells. We documented that KLE cells express IGF-1, IGF-1.R, uPA and IGFBP-3 mRNA, however not uPA.R mRNA. Exogenous...
