Epidermal Growth Factor (EGF) Receptor Kinase Activity is Required for Tumor Necrosis Factor (TNF)-αs required for TNF mediated transactivation of EGFR, ErbB2 and 4 through Src kinase activity and cell survival. Like as Src kinase inhibitor, PI 3-kinase inhibitor enhanced TNF-induced apoptosis, but not MAP kinase inhibitor. From the present study we postulate that EGFR and EGFR tyrosine kinase inv

A Molecular Mechanism of Diminished Binding Activity between 15 bp Deletion Mutant EGFR and c-Cbl Ubtants. As the results, 1) the mutations of Y700F and Y73IF but Y774F reduced binding of wild type EGFR and c-Cbl. 2) all the three mutant c-Cbls showed less binding activity to the mutant EGFR. From these observations, it was suggested that the alteration of substrate specificity for c-Cbl and confo

Role of MT1-MMP in Tumor-Stromal Interactions a tumor-derived mediator to induce MMP-2 expression in fibroblasts after cleaved by MT1-MMP. MT1-MMP cleaves EMMPRIN and released a 22 kDa fragment which has activity to augment expression of MMP-2 in fibropbrasts. Thus, there is a positive feedback loop between the MTl-MMP/MMP-2-dependent tumor g

Drug Accumulation and Efflux Do not Contribute to Acquired Gefitinib Resistancen, cells were lysed and the radioactivities were counted. There was no significant difference of gefitinib accumulation in those cell lines (range 642–731 μmol/g protein at 30 min). The efficiencies of gefitinib-efflux were almost the same in those cell lines (about 80% of gefitinb was discharged at

Difference of EGFR-Binding Proteins between Wild Type and Mutant EGFRing. Much binding of HSP 70 to mutant EGFR was also confirmed by Western blotting. There was no significant difference of HSP 70 protein expression between both transfectant cells. These results suggest that the difference of HSP70 binding to EGFR may modify the EGFR-downstream signaling and influen
