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 کاملMannose 6-phosphate potentiates insulin-like growth factor II effects in cultured human neuroblastoma cells.
Insulin-like growth factor II (IGF-II) and mannose 6-phosphate (man-6-P) bind to distinct sites on the same receptor. In the present study, we examined the effects of man-6-P on the growth promoting effects of IGF-II on SH-SY5Y cultured human neuroblastoma cells. Man-6-P alone increased cell number and neurite outgrowth by approximately 50%; as previously observed, IGF-II increased cell number ...
متن کاملIsolation of the human insulin-like growth factor genes: insulin-like growth factor II and insulin genes are contiguous.
Overlapping recombinant clones that encompass the insulin-like growth factor (IGF) I and II genes have been isolated from a human genomic DNA library. Each gene is present once per haploid genome; the IGF-I gene spans greater than 35 kilobase pairs (kbp) and the IGF-II gene is at least 15 kbp. The exon-intron organization of these genes is similar, each having four exons, which is one more than...
متن کاملStimulation of glucose uptake by insulin-like growth factor II in human muscle is not mediated by the insulin-like growth factor II/mannose 6-phosphate receptor.
Although the growth-promoting effects of insulin-like growth factor II (IGF-II) have been intensively studied, the acute actions of this hormone on glucose metabolism have been less well evaluated, especially in skeletal muscle of humans. We and other groups have shown that IGFs reduce glycaemic levels in humans and stimulate glucose uptake in rat muscle. The purpose of the present study was to...
متن کاملProduction and functional characterization of human insulin-like growth factor 1
Insulin-like growth factor 1 (IGF-1) is a polypeptide hormone produced mainly by the liver in response to the endocrine growth hormone (GH) stimulus. This protein is involved in a wide range of cellular functions, including cellular differentiation, transformation, apoptosis suppression, migration and cell-cycle progression and other metabolic processes. In the current study, human heart cDNA w...
