Islet cell proliferation and apoptosis in insulin-like growth factor binding protein-1 in transgenic mice.
Transgenic mice which overexpress insulin-like growth factor binding protein-1 (IGFPB-1) demonstrate fasting hyperglycemia, hyperinsulinemia and glucose intolerance in adult life. Here we have examined the ontogeny of pancreatic endocrine dysfunction and investigated islet cell proliferation and apoptosis in this mouse model. In addition we have examined pancreatic insulin content in transgenic...
متن کاملImpaired glucose homeostasis in insulin-like growth factor binding protein-1 transgenic mice.
Transgenic mice that overexpressed IGFBP-1 are hyperinsulinemic in the first week of life and gradually develop fasting hyperglycemia. In adult transgenic mice, the hypoglycemic response to IGF-I but not insulin or des (1-3) IGF-I was attenuated (P < 0.05) compared with wild-type mice. Furthermore, in isolated adipocytes from transgenic mice, the stimulatory effect of IGF-I but not insulin on 2...
متن کاملImpaired adipogenesis in insulin-like growth factor binding protein-1 transgenic mice.
Differentiation of precursor cells into mature fat cells is accompanied by enhanced expression of insulin-like growth factor (IGF)-I and is stimulated by multiple hormones including growth hormone, glucocorticoids, IGF-I and insulin. We used transgenic mice that overexpress insulin-like growth factor binding protein-1 to investigate the role of IGF-I in the accumulation of fat tissue. In respon...
متن کاملHepatic regeneration in insulin-like growth factor binding protein-1 transgenic mice.
BACKGROUND/AIMS Partial hepatectomy results in activation of genes in the residual liver tissue which serve to restore glucose homeostasis and regenerate liver mass. Expression of insulin-like growth factor binding protein-1 (IGFBP-1) is up-regulated following partial hepatectomy and IGFBP-1 can modulate both the metabolic and mitogenic effects of insulin-like growth factor-1 (IGF-I). The aim o...
متن کاملInsulin-like growth factor-binding protein-4 inhibits growth of the thymus in transgenic mice.
Numerous in vitro studies have demonstrated that IGF-binding protein (IGFBP)-4 is a consistent inhibitor of IGF actions. In order to investigate the functions of IGFBP-4 in vivo, transgenic mice were generated by microinjection of a transgene, in which the murine Igfbp4 cDNA is driven by the H-2K(b) promoter, and followed by a splicing cassette and polyadenylation signal of the human beta-globi...
