Vertex balding, plasma insulin-like growth factor 1, and insulin-like growth factor binding protein 3.
BACKGROUND A recent report suggested that men with vertex balding have higher levels of plasma insulin-like growth factor 1 (IGF-1). The association of its major carrier protein, insulin-like growth factor binding protein 3 (IGFBP-3), with male pattern hair loss has not been examined. OBJECTIVE We evaluated the relations of plasma concentrations of IGF-1 and IGFBP-3 with vertex balding in mid...
متن کاملVariation in plasma insulin-like growth factor-1 and insulin-like growth factor binding protein-3: genetic factors.
Insulin-like growth factors (IGFs) play key roles in cell proliferation and apoptosis. Whereas relatively stable within individuals, IGFs vary substantially between individuals, and a large component of this variation may be determined by genetic factors. Several polymorphisms in IGF genes have been identified, although their functional significance is not clear. We evaluated the association of...
متن کاملThe Effect of 8 Weeks Resistance Training With Low Load and High Load on Testosterone, Insulin-like Growth Factor-1, Insulin-like Growth Factor Binding Protein-3 Levels, and Functional Adaptations in Older Women
Objectives The loss of muscle mass in older adults is attributed to the impaired ability of the skeletal muscle in response to anabolic stimuli and the increased activation of the proteolytic signaling pathway. With increasing age, plasma concentrations of circulating anabolic hormones and growth factors, e.g. testosterone, Insulin-like Growth Factor-1 (IGF-1) and Insulin-like Growth Factor Bin...
متن کاملInsulin-like growth factor I and insulin-like growth factor binding protein 5 in Crohn's disease.
Insulin-like growth factor (IGF)-I and its binding protein IGF binding protein 5 (IGFBP-5) were highly expressed in inflamed and fibrotic intestine in experimental Crohn's disease. IGF-I induced proliferation and increased collagen synthesis by smooth muscle cells and fibroblasts/myofibroblasts in vitro. Here we studied IGF-I and IGFBP-5 in Crohn's disease tissue. Tissue was collected from pati...
متن کاملInsulin-like growth factors sustain insulin-like growth factor-binding protein-5 expression in osteoblasts.
Insulin-like growth factors (IGFs) I and II are considered to be autocrine regulators of bone cell function. Recently, we demonstrated that IGF-I induces IGF-binding protein-5 (IGFBP-5) expression in cultures of osteoblast-enriched cells from 22-day fetal rat calvariae (Ob cells). In the present study, we postulated that IGFs play an autocrine role in the maintenance of IGFBP-5 basal expression...
