Insulin antibodies retard and insulin accelerates growth and differentiation in early embryos.
The physiologic function of insulin in early embryonic life is unknown. We have shown that insulin is present in unfertilized eggs and in chick embryos at 2-3 days of development, even before the emergence of the endocrine pancreas. To define insulin's role, we exposed 2-day-old chick embryos to anti-insulin antibodies and followed their development up to day 5. Antibody-treated embryos had a h...
متن کاملInsulin in blood and insulin antibodies.
T HIS presentation is concerned with the state of insulin in plasma rather than the physiologic regulation of insulin secretion. Our own studies on the concentrations of immunoassayable insulin in blood in hyperglycemic and hypoglycemic states have recently been summarized elsewhere [ 7-31. Since insulin in blood has never been extracted and recovered in amounts sufficient to permit its chemica...
متن کاملInsulin-like growth factor-2 regulates early neural and cardiovascular system development in zebrafish embryos.
The insulin-like growth factor (IGF) family is essential for normal embryonic growth and development and it is highly conserved through vertebrate evolution. However, the roles that the individual members of the IGF family play in embryonic development have not been fully elucidated. This study focuses on the role of IGF-2 in zebrafish embryonic development. Two igf-2 genes, igf-2a and igf-2b, ...
متن کاملThe Insulin-like Growth Factor-1 (G>A) and 5,10-methylenetetrahydrofolate Reductase (C677T) Gene Variants and the Serum Levels of Insulin-like Growth Factor-1, Insulin, and Homeostasis Model Assessment in Patients with Acne Vulgaris
Background & Objective: To find an association between gene variants of insulin-like growth factor-1 (IGF-1) and 5,10-methylenetetrahydrofolate reductase (MTHFR) with the risk of acne vulgaris (AV). Methods: In a case-control study, we investigated 150 AV patients and 148 healthy individuals (aged 18-25 years) for the IGF-1 G>A and MTHFR C677T polymorphis...
متن کاملInsulin, insulin-like growth factors and neoplasia.
Over the past decade, dozens of epidemiological studies and laboratory experiments have provided evidence for relationships between insulin-like growth factor (IGF) physiology and neoplasia. Population studies provide evidence for a modestly increased risk of a subsequent cancer diagnosis in subjects with IGF-I levels at the high end of the broad normal range, as compared to those at the low en...
