Growth hormone, insulin-like growth factor-1 and the aging cardiovascular system.
There is a large body of evidence that biological aging is related to a series of long-term catabolic processes resulting in decreased function and structural integrity of several physiological systems, among which is the cardiovascular system. These changes in the aging phenotype are correlated with a decline in the amplitude of pulsatile growth hormone secretion and the resulting decrease in ...
متن کاملInsulin-like Growth Factor System and Aging
IGF (insulin-like growth factor, IGF) system is composed of three ligands (insulin, IGF-1, IGF-2), three cell surface binding receptors (Ins R, IGF-1R, IGF-2 R), and Insulin-like growth factor binding proteins (IGF binding proteins, IGFBPs) and IGFBP protease. Delaying aging and exploring the molecular mechanism of aging have always been important research topics. IGF system plays an important ...
متن کاملInsulin-like growth factor 1 (IGF-1): a growth hormone.
AIM To contribute to the debate about whether growth hormone (GH) and insulin-like growth factor 1 (IGF-1) act independently on the growth process. METHODS To describe growth in human and animal models of isolated IGF-1 deficiency (IGHD), such as in Laron syndrome (LS; primary IGF-1 deficiency and GH resistance) and IGF-1 gene or GH receptor gene knockout (KO) mice. RESULTS Since the descri...
متن کاملGrowth Hormone and Insulin-Like Growth Factor-1.
Human growth hormone (GH) was first isolated from the human pituitary gland in 1945 and found to promote the growth of children with hypopituitarism. Since the formation of the World Anti-Doping Association, human GH has appeared on the list of forbidden substances. There is a significant amount of anecdotal evidence that human GH is misused by athletes to enhance performance, and there have be...
متن کاملMinireview: role of the growth hormone/insulin-like growth factor system in mammalian aging.
The important role of IGF and insulin-related signaling pathways in the control of longevity of worms and insects is very well documented. In the mouse, several spontaneous or experimentally induced mutations that interfere with GH biosynthesis, GH actions, or sensitivity to IGF-I lead to extended longevity. Increases in the average life span in these mutants range from approximately 20-70% dep...
