The majority of insulin-like growth factor (IGF)-I and IGF-II circulate in the serum as a complex with the insulin-like growth factor binding protein (IGFBP)-3 or IGFBP-5, and an acid-labile subunit (ALS). The function of ALS is to prolong the half-life of the IGF-I-IGFBP-3/IGFBP-5 binary complexes. Fourteen different mutations of the human IGFALS gene have been identified in 17 patients, sugge...
Abstract Background and purpose: Delayed wound healing is a common complication of diabetes mellitus. However, less is known about the cause of this pathology. Types of skin cells, extracellular matrix and variety of growth factors are involved in wound healing. The use of recombinant growth factors in researches and production of skin substitutes are still a challenge. Much research has bee...
This experiment was designed to study the effect of insulin like growth factor-I (IGF-I) on cryopreservation of Hariana bull semen. For this purpose, semen ejaculates were collected from four Hariana bulls using artificial vagina at biweekly interval. The semen samples which possess more than 70% initial progressive motility and above 500 million/mL spermatozoa concentration was subsequently su...
Abstract Introduction: There is limited knowledge available on the metabolism of glucose in the brain, an insulin insensitive organ. Insulin receptors hybridize with insulin like growth factor receptor (IGF-I) to transduce the signals in different areas of the brain. In this article we aimed at investigating whether the expression of IGF-I receptor and IGF-I binding proteins (IGFBP1) is change...
Insulin-like growth factor 1 receptor (IGF-1R) activation is required for prostate cell proliferation. Prostate cancer is one of the most commonly diagnosed malignant tumors in Western countries. Overexpression of IGF-1R in prostate cancer is associated with tumor growth. These suggest that IGF-1R inhibitory agents may be of preventive and/or therapeutic value. With evidence accumulating for a ...
The involvement of the insulin-like growth factor (IGF) system in lung growth and repair following injury is sustained by a number of studies. Based on this knowledge, the aim of the present work was to document the expression of the IGFs and their binding proteins by alveolar cells obtained by bronchoalveolar lavage (BAL). Two groups were investigated: a control group of five children and a gr...
Purpose: This study investigated the effect of endurance activity on brain-derived neurotrophic factor(BDNF), insulin-like growth factor 1(IGF-1) and its binding protein 3(IGFBP-3) in elderly healthy individuals. Materials and Methods: Eleven healthy old males (mean age of 68 ± 2.31 years old, height of 177 ± 3.1 cm and weight of 79 ± 1.5 kg) were studied. Seventy two hours after maxi...
Components of the insulin-like growth factor (IGF) system were investigated in chondrocytes isolated from the avian growth plate. The genes for IGF-I, IGF-II, type 1 IGF receptor (IGF-R), IGF binding protein-2 (IGFBP-2), IGFBP-3, IGFBP-5 and IGFBP-7 were found to be expressed in both proliferative and hypertrophic chondrocytes. The expression of IGF-II in proliferative chondrocytes was extremel...
Insulin-like growth factor-1 (IGF-1) plays a role in the regulation of myocardial structure and function. IGF-1 is capable of improving cardiac muscle survival, growth, calcium signaling, and differentiation.1 Among various actions of IGF-1 on heart, the ability of IGF-1 to counteract apoptosis of cardiomyocytes has drawn significant attention in recent years. IGF-1 suppresses myocardial apopto...
