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 کاملUnderstanding the Mechanism of Insulin and Insulin-Like Growth Factor (IGF) Receptor Activation by IGF-II
BACKGROUND Insulin-like growth factor-II (IGF-II) promotes cell proliferation and survival and plays an important role in normal fetal development and placental function. IGF-II binds both the insulin-like growth factor receptor (IGF-1R) and insulin receptor isoform A (IR-A) with high affinity. Interestingly both IGF-II and the IR-A are often upregulated in cancer and IGF-II acts via both recep...
متن کاملIGFBP7 binds to the IGF-1 receptor and blocks its activation by insulin-like growth factors.
Insulin-like growth factor-binding protein 7 (IGFBP7) is a secreted factor that suppresses growth, and the abundance of IGFBP7 inversely correlates with tumor progression. Here, we showed that pretreatment of normal and breast cancer cells with IGFBP7 interfered with the activation and internalization of insulin-like growth factor 1 receptor (IGF1R) in response to insulin-like growth factors 1 ...
متن کاملRadioimmunoassay for insulin-like growth factor II (IGF-II).
Insulin-like growth factor II (IGF-II) levels in human plasma were measured in physiological and pathological conditions by radioimmunoassay (RIA) with biosynthetic IGF-II. This RIA was specific for IGF-II and cross-reactivity with IGF-I was 1%. The sensitivity was 15 pg/tube with 50% displacement at 50 pg/tube. The intra- and inter-assay coefficients of variation for IGF-II were 6.3 and 9.3%, ...
متن کاملInsulin-like growth factor 1 (IGF-1): a growth hormone.
AIM To contribute to the debate about whether growth hormone (GH) and insulin-like growth factor 1 (IGF-1) act independently on the growth process. METHODS To describe growth in human and animal models of isolated IGF-1 deficiency (IGHD), such as in Laron syndrome (LS; primary IGF-1 deficiency and GH resistance) and IGF-1 gene or GH receptor gene knockout (KO) mice. RESULTS Since the descri...
