Insulin-like growth factors and binding proteins in ruminants and their nutritional regulation.
Insulin-like growth factors (IGF) are important mediators of growth, lactation, reproduction, and health. Considerable information on their role in ruminant animals has been learned in the past several years, but the precise mechanisms of their action are not known. The exact biological response of target cells is undoubtedly determined by the developmental state of the cell and synergism with ...
متن کاملPolycystic ovary syndrome (PCOS), insulin resistance and insulin-like growth factors (IGfs)/IGF-binding proteins (IGFBPs).
Polycystic ovary syndrome (PCOS) is the most frequent androgen disorder of ovarian function. Hyperinsulinemia with insulin resistance is believed to be a key link in the enigmatic generation of the symptoms of PCOS such as anovulatory infertility and hyperandrogenism. Regression of these symptoms may be achieved by reducing the hyperinsulinemia. A growing body of evidence suggests that PCOS pat...
متن کاملCirculating levels of insulin-like growth factors, their binding proteins, and breast cancer risk.
BACKGROUND Earlier data support the hypothesis that the relation between circulating insulin-like growth factor-I (IGF-I) levels and breast cancer risk differs by menopausal status. The strong association of IGF-I with height in childhood and weak or no association between adult levels and adult height also suggest that IGF levels in young women may better reflect an exposure time period of imp...
متن کاملThe Role of the Insulin-Like Growth Factors and Their Binding Proteins in Glucose Homeostasis
The insulin like growth factors (IGF-I and -II) are structurally and functionally related to insulin. While insulin is a key regulator of glucose homeostasis over the short term, emerging evidence suggests that the IGFs are involved in the longer term glucose homeostasis, possibly by modulating insulin sensitivity. Unlike insulin, the IGFs are present in most biological fluids as complexes with...
متن کاملInsulin-like growth factors (IGFs) and IGF-binding proteins (IGFBP-1, -2 and -3) in diabetic pregnancy: relationship to macrosomia.
To evaluate the role of insulin-like growth factors (IGFs) and IGF-binding proteins (IGFBPs) in excessive fetal growth (macrosomia) in diabetic pregnancy, 84 insulin-treated diabetic mothers and their infants were tested for serum concentrations of IGF-I, IFG-II, and IGFBP-1, -2 and -3. These parameters were correlated with the birth weight of neonates and placental weight. IGF-I and II levels ...
