Ionizing radiation induces an intracellular stress response via activation of the phosphatidylinositol 3'-kinase (PI3K)/Akt survival pathway. In tumor cells, the PI3K/Akt pathway is induced through activation of members of ErbB receptor tyrosine kinases. Here, we investigated the receptor dependence of radiation-induced PI3K/Akt activation in tumor cells and in endothelial cells. The integrity ...
Receptor-mediated targeted tumor therapy is an important applied consequence of the studies on the genetic causes of cancer. These therapy concepts have to be evaluated in novel animal models that reflect the molecular aberrations found in human tumors. Here we introduce an animal model that allows the evaluation of drugs directed against a surface receptor that is frequently altered in primary...
The epidermal growth factor (EGF) receptor (EGFR, HER1, ErbB1) and human epidermal growth factor receptor type 2 (HER2, ErbB2) belong to the ErbB family of type I tyrosine kinases (TKs). This family of receptor TKs also includes another two closely related members HER3/ErbB3 and HER4/ErbB4. The general structure of these cell surface receptor proteins contains an extracellular ligand-binding do...
BACKGROUND The epidermal growth factor receptor kinases, or ErbB kinases, belong to a large sub-group of receptor tyrosine kinases (RTKs), which share a conserved catalytic core. The catalytic core of ErbB kinases have functionally diverged from other RTKs in that they are activated by a unique allosteric mechanism that involves specific interactions between the kinase core and the flanking Jux...
BACKGROUND The ErbB receptor tyrosine kinases and nucleolin are major contributors to malignant transformation. Recently we have found that cell-surface ErbB receptors interact with nucleolin via their cytoplasmic tail. Overexpression of ErbB1 and nucleolin leads to receptor phosphorylation, dimerization and anchorage independent growth. METHODOLOGY/PRINCIPAL FINDINGS In the present study we ...
Multiple factors lead to the development and maintenance of chronic heart failure. Blockade of ErbB-2 or ErbB-4 tyrosine kinase receptor signaling leads to dilated cardiomyopathy. ErbB-1 may protect the heart against stress-induced injury and its ligand; epidermal growth factor (EGF) increases myocardial contractility, whereas heparin-binding EGF is essential for normal cardiac function. Howeve...
Signaling through the erbB receptor family of tyrosine kinases contributes to the proliferation, differentiation, migration, and survival of a variety of cell types. Abnormalities in members of this receptor family have been shown to play a role in oncogenesis, thus making them attractive targets for anticancer treatments. PF-00299804 is a second-generation irreversible pan-erbB receptor tyrosi...
The majority of the bioactives under investigation were predicted to target TNF receptor-associated factor 5 in Janus kinase/signal transducers and activators transcription pathway. Similarly, druglikeness prediction identified vitexilactone possess highest score, i.e., 0.88. Furthermore, proteins targeted pathway also regulate multiple pathways, ErbB, AGE-RAGE, NF-kappa B, Measles, insulin, mT...
Integral membrane proteins contain a hydrophobic transmembrane domain and mainly locate in the plasma membrane lipid bilayer. The receptor tyrosine kinases (RTK) of the epidermal growth factor receptor (EGFR) superfamily, including ErbB-1, ErbB-2, ErbB-3, and ErbB-4, constitute an important group of such membrane proteins, which have a profound impact on cancer initiation, progression, and pati...
