The growth hormone-insulin-like growth factor-I axis.
The aim of the GH-2000 project is to develop a method for detecting GH doping among athletes. Previous papers in the GH-2000 project have proposed that a forthcoming method to detect GH doping will need specific components from the GH/IGF-I axis and bone markers because these specific variables seem more sensitive to exogenous GH than to exercise. The present study examined the responses of the...
متن کاملOntogenic maturation of the somatotropin/insulin-like growth factor axis.
The ontogeny of the somatotropin/insulin-like growth factor system was examined in well-fed pigs under basal conditions and during a short-term challenge of porcine ST (pST). The study was conducted with two replicates of eight castrate male pigs from 3.8 kg BW (10 d of age) to 92 kg BW (129 d of age). Pigs were reared individually with ad libitum access to milk replacer through 23 d of age. Th...
متن کاملInsulin-like growth factor-I: compartmentalization within the somatotropic axis?
Insulin-like growth factor-I (IGF-I) is essential for normal growth; igf-1 gene mutations are associated with extreme growth retardation in mice and, very rarely, in humans. The relative contributions of tissue vs. endocrine (hepatic) IGF-I to the regulation of growth has been a fundamental question. New gene targeting technologies are providing answers for these questions.
متن کاملTargeting insulin-like growth factor axis in hepatocellular carcinoma
The insulin-like growth factor (IGF) axis contains ligands, receptors, substrates, and ligand binding proteins. The essential role of IGF axis in hepatocellular carcinoma (HCC) has been illustrated in HCC cell lines and in animal xenograft models. Preclinical evidence provides ample indication that all four components of IGF axis are crucial in the carcinogenic and metastatic potential of HCC. ...
متن کاملInsulin, the insulin-like growth factor axis, and mortality in patients with nonmetastatic colorectal cancer.
PURPOSE Obesity, sedentary lifestyle, and Western dietary pattern have been linked to increased risk of cancer recurrence and mortality among patients with surgically resected colorectal cancer. Excess energy balance leads to increased circulating insulin and depressed levels of circulating insulin-like growth factor binding protein (IGFBP) -1, which promote cancer cell growth in preclinical mo...
