ANTISENSE RNA TO THE TYPE I INSULIN-LIKE GROWTH FACTOR RECEPTOR REVERSED THE TRANSFORMED PHENOTYPE OF PC-3 HUMAN PROSTATE CANCER CELL LINE IN VITRO
The insulin-like growth factor I receptor (IGF-IR) plays an essential role in the establishment and maintenance of transformed phenotype. Interference with the IGF-IR pathway by antisense causes reversal of the transformed phenotype in many rodent and human tumor cell lines. We stably transfected the PC-3 human prostate cancer cell line with an IGF-IR antisense RNA expression plasmid. The ...
متن کاملActivation of various downstream signaling molecules by IGFBP-3.
Insulin-like growth factor binding protein-3 (IGFBP-3), a secretory protein, is the most abundant IGF binding protein present in human serum among all IGF binding proteins. IGFBP-3 shows decreased level of expression in cancerous cells but has been known to be present in significant amounts in normal or non-cancerous cells. IGFBP-3 can induce apoptosis in prostate cancer cells either in an IGF-...
متن کاملEffects of Inflammatory Cytokine Tumor Necrosis Factor-α on Human Mesenchymal Stem Cell Gene Expression: A Mechanism for Liver Regeneration
Introduction Insulin-like growth factor I (IGF-I) which is produced in abundance in the normal adult liver, is deeply involved in hepatocyte survival, growth, and differentiation during liver development. IGF-I plays the roles via the receptor (IGF-IR) signaling pathway. IGF-IR unlike IGF-I is expressed strongly in the developing liver, but much more weakly in adults. Objective: We hypothesi...
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...
متن کاملOptimization 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...
