EGFR, epidermal growth factor receptor (ErbB1EGF, epidermal growth factorTGFα, transforming growth factor αHRG, heregulin, also called neu differentiation factor (NDF) or neuregulin (NRGEPR, epiregulinHB-EGF, heparin-binding egfBTC, betacellulin...
Scatchard analysis of EGF binding curve indicated that 7404 and 7721 cells expressed approximately 1.1 x 10(5) and 0.7 x 10(5) EGFRs per cell with binding affinity (Kd) 2.1 nM and 1.8 nM respectively. Northern hybridization and immunoblotting analysis showed the EGFR gene expression products ...
547 SPSB1 and ubiquitylation of hnRNP A1 have a critical role in mediating EGF-stimulated cell migration EGF/EGFR signaling is crucial for promoting cell migration and tumor metastasis. Thus, we next asked whether EGF signaling-induced ubiquitylation of hnRNP A1 has a role in regulating cell ...
Epidermal growth factor (EGF) is characterized by high affinity binding to various EGF receptors (EGFRs) and the production of mitogenic responses (Carpenter & Cohen). EGF promotes EGFR dimerization, resulting in activation of downstream pathways including PI3K, ERK1/2, JAK/STAT, β-catenin, and...
In dark field microscopy, Similar responses by tagged and control cells does not confirm the binding affinity. Novel EGFR-specific gold and silver nanoprobes were synthesized and validated by standard assay as SERS optical imaging probes. 展开 ...
The goal of this proposal is to use directed evolution to generate EGF mutants with enhanced binding affinities to the extracellular domains of the epidermal growth factor receptor (EGFR). The rationale is that EGF mutants with increased binding affinity to different receptor subdomains will elicit ...

Cetuximab binds to the extracellular domain of EGFR at a higher affinity than EGF, preventing ligand binding and phosphorylation of the receptor [[43], [44], [45]]. Triple negative breast cancers tend to have the highest proportion of EGFR overexpression out of the breast cancer subtypes [[9...
Kd value revealed high affinity for EGF binding: 0.645 +/- 0.769 nmol/l. EGFR values were determined by a simplified competition method using a radiolabeled ligand. EGFR was found to be more elevated in tumours (n = 20) than in normal tissue (n = 4): (59.5 vs 10.5 fmol/mg proteins)...
EGF signals via EGF Receptor (EGFr, ErbB1, or HER1), which is a type 1 tyrosine kinase receptor and can also bind several other EGF-like proteins. Binding of EGF to EGFr triggers receptor dimerization, autophosphorylation, and internalization of the receptor-ligand complex. EGF and its ...
