Optimization and Construction of Human Insulin-like Growth Factor 1 Gene related to human health
Background and aims: Laron syndrome is a disease that treated by Insulin-like Growth Factor 1 (IGF-1). This protein is a single chain and has three disulfide bonds. People with Laron syndrome have low rates of cancer and diabetes, although they appear to be at increased risk of casual death due to their stature. IGF-1 is synthesized by many tissues and is secreted from liver as an endocrine hor...
متن کاملAmino acid regulation of gene transcription of rat insulin-like growth factor-binding protein-1.
To investigate the molecular mechanisms of increased transcription of the insulin-like growth factor-binding protein-1 (IGFBP-1) gene in dietary protein-deprived animals, the cis-acting sequence that is involved in this regulation was analyzed. We first showed that IGFBP-1 gene transcription was up-regulated by amino acid deprivation in cultured liver cell lines: H4IIE and HuH-7. Since HuH-7 ce...
متن کاملVertex 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 کاملThe role of insulin-like growth factor 1 and insulin-like growth factor binding protein 3 in human esophageal cancer.
BACKGROUND Insulin-like growth factors (1GF-1) and insulin-like growth factor binding protein-3 (IGFBP-3) play important roles in cell growth and differentiation. The aim of this work was to investigate the roles of IGF-1 and IGFBP-3 in esophageal cancer. MATERIALS AND METHODS We examined the circulating IGF-1 and IGFBP-3 concentration in 18 healthy controls and 66 esophageal cancer patients ...
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...
