Regulation of human fibroblast insulin-like growth factor (IGF)-binding proteins by IGF-1 and cytokines, mechanisms of action and effects upon IGF bioactivity [PDF]

, 1995
PhDThe insulin-like growth factors, IGF-I and IGF-II, are ubiquitous polypeptide molecules that have mitogenic and metabolic actions in a wide variety of cell types, and consequently play a major role in mammalian growth and development.

Molecular evolution and functional characterization of Drosophila insulin-like peptides [PDF]

, 2010
Multicellular animals match costly activities, such as growth and reproduction, to the environment through nutrient-sensing pathways. The insulin/IGF signaling (IIS) pathway plays key roles in growth, metabolism, stress resistance, reproduction, and ...

Insulin-Like Growth Factor-1 as a Vascular Protective Factor [PDF]

Circulation, 2004
Recent advances in cardiology have focused on proliferation and regeneration as potential cardiovascular defense mechanisms. Within this framework, growth factors are acquiring increasing importance; insulin-like growth factor-1 (IGF-1) emerges among them for its versatile pleiotropic actions.

Gene expression patterns of insulin-like growth factor 1, insulin-like growth factor 2 and insulin-like growth factor binding protein 3 in human placenta from pregnancies with intrauterine growth restriction [PDF]

, 2011
Introduction: In this study, we compared insulin-like growth factor (IGF)-gene expression patterns and characteristics of glucose and insulin metabolism in human placenta from pregnancies with or without intrauterine growth restriction (IUGR).

Estradiol, Progesterone, and Transforming Growth Factor α Regulate Insulin-Like Growth Factor Binding Protein-3 (IGFBP3) Expression in Mouse Endometrial Cells [PDF]

, 2009
Insulin-like growth factor 1 (IGF1) Is Involved in the proliferation of mouse and rat endometrial cells in a paracrine or autocrine manner. Insulin-like growth factor binding protein-3 (IGFBP3) modulates actions of IGFs directly or indirectly.

Proteolysis of insulin-like growth factor binding proteins (IGFBPs) by calpain [PDF]

, 2005
Calpains are non-lysosomal, Ca2+-dependent cysteine proteases, which are ubiquitously distributed across cell types and vertebrate species. The rules that govern calpain specificity have not yet been determined.

IGF-Binding Proteins: Why Do They Exist and Why Are There So Many?

Frontiers in Endocrinology, 2018
Insulin-like growth factors (IGFs) are key growth-promoting peptides that act as both endocrine hormones and autocrine/paracrine growth factors. In the bloodstream and in local tissues, most IGF molecules are bound by one of the members of the IGF ...

Insulin-like growth factor 1 receptor mediates photoreceptor neuroprotection

Cell Death and Disease, 2022
Insulin-like growth factor I (IGF-1) is a neurotrophic factor and is the ligand for insulin-like growth factor 1 receptor (IGF-1R). Reduced expression of IGF-1 has been reported to cause deafness, mental retardation, postnatal growth failure, and ...

Insulin-Like Growth Factor 1 in Patients with Hypoglycaemia [PDF]

Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 1990
Plasma insulin-like growth factor 1 (IGF-1) concentrations were measured in a group of patients with hypoglycaemia due to endogenous hyperinsulinism, and compared with those in a group of patients matched for age and sex with hypoglycaemia and appropriately suppressed insulin levels. Insulin-like growth factor I concentrations were significantly higher

Development of real-time reverse transcription polymerase chain reaction assays to quantify insulin-like growth factor receptor and insulin receptor expression in equine tissue

Onderstepoort Journal of Veterinary Research, 2013
The insulin-like growth factor system (insulin-like growth factor 1, insulin-like growth factor 2, insulin-like growth factor 1 receptor, insulin-like growth factor 2 receptor and six insulin-like growth factor-binding proteins) and insulin are essential
