Findings demonstrate that, in human breast cancer cells, DDR1 (show DDR1 Proteins) regulates IR expression and ligand dependent biological actions. This novel functional crosstalk is likely clinically relevant.
in beta cells, INSR-B has a protective role, while INSR-A expression sensitizes beta cells to programmed cell death.
These results support the hypothesis that INSR gene expression in different areas of Alzheimer's patient's brains.
In endocrine-sensitive breast cancer cells, insulin (show INS Proteins) was not growth stimulatory, likely due to the presence of hybrid InsR/IGF1R (show IGF1R Proteins), which has high affinity for IGF-I (show IGF1 Proteins), but not insulin (show INS Proteins). Combination inhibition of InsR and IGF1R (show IGF1R Proteins) showed complete suppression of the system in endocrine-sensitive breast cancer cells
Report complex relationships between individual tumor-specific expression of IGF1R (show IGF1R Proteins)/pIGF1R and InsR/pInsR, response endocrine treatment and breast cancer prognosis.
analysis of compounds that cause IGF-1Rbeta but not Insulin Receptor degradation specifically in tumor cells with no effects seen in normal diploid fibroblasts
The gained results are observed not only the unbinding mechanism of IRK (show KCNJ12 Proteins)-PTP1B (show PTPN1 Proteins) complexes came from pulling force profile, number of hydrogen bonds, and interaction energy between IRK (show KCNJ12 Proteins) and PTP1Bs but also described PTP1B's point mutations could variably change its binding affinity towards IRK (show KCNJ12 Proteins).
The data in this paper demonstrate that IR knockdown in primary tumors partially reverses the growth-promoting effects of hyperinsulinemia as well as highlighting the importance of the insulin receptor signaling pathway in cancer progression, and more specifically in epithelial-mesenchymal transition.
INSR rs2252673 and rs3745546 polymorphisms were associated with sensitivity to platinum-based chemotherapy in epithelial ovarian cancer patients and rs2252673 polymorphism may be an independent risk factor for EOC prognosis.
The IGF1R (show IGF1R Proteins) purified in n-dodecyl-beta-D-maltoside showed ligand-stimulated autophosphorylation and kinase activity, suggesting an intact transmembrane signaling mechanism.
we show that glucagon receptor (GCGR (show GCGR Proteins)) inhibition with a monoclonal antibody normalized blood glucose and beta-hydroxybutyrate levels. Insulin receptor antagonism increased pancreatic beta-cell mass threefold. Normalization of blood glucose levels with GCGR (show GCGR Proteins)-blocking antibody unexpectedly doubled beta-cell mass relative to that observed with S961 alone and 5.8-fold over control
Data (including data from studies in knockout mice) suggest double knockout (DKO) mice lacking Insr and Igf1r (show IGF1R Proteins) exhibit obesity with insulin (show INS Proteins) resistance and increased adiposity; on high-fat diet, DKO mice exhibit metabolic syndrome. (Insr = insulin receptor; Igf1r (show IGF1R Proteins) = insulin-like growth factor I receptor (show IGF1R Proteins))
long-term hepatic expression of IRA could be a promising therapeutic approach for the treatment of type 2 diabetes mellitus.
the overlap of IR and IGF1R (show IGF1R Proteins) signaling is critical to the regulation of muscle protein turnover, and this regulation depends on suppression of FoxO (show FOXO3 Proteins)-regulated, autophagy-mediated protein degradation
These data reveal a critical pathophysiological role for INSR Thr1160 phosphorylation and provide further mechanistic links between PKCepsilon (show PRKCE Proteins) and INSR in mediating Nonalcoholic fatty liver disease -induced hepatic insulin (show INS Proteins) resistance.
Insr was downregulated in the arcuate nucleus of type 2 diabetic mice.
Mice lacking the insulin receptor in AgRP (show AGRP Proteins) neurons (AgRP (show AGRP Proteins) IR KO) exhibited impaired hepatic insulin (show INS Proteins) action because the ability of insulin (show INS Proteins) to suppress hepatic glucose production (hGP) was reduced, but the ability of insulin (show INS Proteins) to suppress lipolysis was unaltered. To the contrary, in POMC (show POMC Proteins) IR KO mice, insulin (show INS Proteins) lowered hGP but failed to suppress adipose tissue lipolysis.
Intracellular retention of the insulin receptor is caused by elevated amounts of alpha-taxilin (show TXLNA Proteins), a free syntaxin binding protein, in HBV expressing hepatocytes preventing proper targeting of the insulin receptor to the cell surface.
Impairment of insulin (show INS Proteins) signalling in the mushroom body neurons, a structure involved in associative learning, impairs feeding behaviour in the Drosophila larva.[Insulin (show INS Proteins)]
it was demonstrated that InR was expressed in follicular cells and that its expression in corpus allatum and follicular cells of Drosophila females was stage-specific, i.e., the expression intensity in young females greatly exceeded that in mature individuals.
INR signaling promotes glial phagocytic clearance of degenerating axons through regulation of Draper.
These results demonstrate that Dock selectively enhances the PTP61Fm-mediated attenuation of InR signalling and underscores the specificity of PTPs and the importance of adaptor proteins in regulating PTP function in vivo.
Mactosylceramide, an early product in GSL (show CTSA Proteins) biosynthesis, prevents inappropriate activation of insulin (show INS Proteins) and fibroblast growth factor receptors in Drosophila glial cells and hypertrophy.
Results show that lifespan and behavioral senescence are independently regulated by the Drosophila insulin receptor.
Study shows that the increase in the dopamine level in D. melanogaster females with the InR gene knockdown in corpus allatum ensures their increased resistance to starvation-induced stress
results indicate that the Drosophila insulin-like peptide system is a crucial regulator of sleep
This study has shown for the first time that suppression of InR expression in VNC leads to a rise in the survival of flies under conditions of toxic stress.
The combined activities of Stit and InR in ectodermal epithelial tissues provide an RTK-mediated, two-tiered reaction threshold to varying nutritional conditions that promote epithelial organ growth even at low levels of InR signaling.
studied by RT reverse-transcription PCR, whether there are differences in the abundance of mRNA coding for IGF-I (show IGF1 Proteins), IGF-2, IGFBP-2, IGFBP-3 (show IGFBP3 Proteins), IGF-1R (show IGF1R Proteins), IGF-2R, GHR (show GHR Proteins), and InsR in compartmentalized layers of jejunum and ileum of 5-d-old calves fed colostrum
insulin receptor and phosphoinositide 3-kinase localize to detergent-resistant membrane rafts of rod photoreceptor outer segments
FSH (show BRD2 Proteins), but not E2, stimulated the expression of IR and GHR (show GHR Proteins) genes during follicular development.
Data conclude that insulin (show INS Proteins) and IGF-I (show IGF1 Proteins) receptors differentially mediate the production of adhesion molecules by ECs and monocyte adhesion onto the vascular endothelium in response to the hyperinsulinemic state.
After removal of the precursor signal peptide, the insulin receptor precursor is post-translationally cleaved into two chains (alpha and beta) that are covalently linked. Binding of insulin to the insulin receptor (INSR) stimulates glucose uptake. Two transcript variants encoding different isoforms have been found for this gene.
