Epidermal growth factor receptor dynamics influences response to epidermal growth factor receptor targeted agents.
Analysis of gene expression of cancer cell lines exposed to erlotinib, a small molecule inhibitor of the epidermal growth factor receptor (EGFR), showed a marked increase in EGFR mRNA in resistant cell lines but not in susceptible ones. Because cetuximab induces EGFR down-regulation, we explored the hypothesis that treatment with cetuximab would interfere with erlotinib-induced EGFR up-regulati...
متن کاملAltered Expression of Epidermal Growth Factor Receptor (EGFR) in Glioma
EGFR is a key molecule in cancer cells. EGFR signaling was shown to promote tumor cell proliferation and survival, invasion and angiogenesis and mediate resistance to treatment, including ionizing radiation in preclinical models. We extracted proteins from astrocytoma (III and IV) oligodendroglioma(IV) tumors and normal brain tissues and then evaluated the protein purity by Bradford test ...
متن کاملAssessment of epidermal growth factor receptor status in glioblastomas
Objective(s): Our previous study showed that a newly designed tracer radioiodinated 6-(3-morpholinopropoxy)-7-ethoxy-4-(3'-iodophenoxy)quinazoline ([125I]PYK) is promising for the evaluation of the epidermal growth factor receptor (EGFR) status and prediction of gefitinib treatment of non-small cell lung cancer. EGFR is over-expressed and mutated also in glioblastoma. In the present study, the ...
متن کاملAn epidermal growth factor receptor intron 1 polymorphism mediates response to epidermal growth factor receptor inhibitors.
This study tested the hypothesis that the number of CA single sequence repeat (CA-SSR) in the intron 1 of the epidermal growth factor receptor (egfr) gene, which affects transcription efficiency of the gene, is associated with the response to EGFR inhibitors. To this end, we determined the number of CA dinucleotides in the intron 1 of the egfr gene in a panel of 12 head and neck cancer cell lin...
متن کاملEpidermal growth factor receptor-targeted agents for lung cancer.
BACKGROUND Approximately 150,000 people were diagnosed with non-small cell lung cancer (NSCLC) in the United States in 2005. Most presented with inoperable advanced-stage disease. Although combination chemotherapy remains the standard treatment, median survival with these regimens is only 8 to 10 months. Recent advances in our understanding of lung cancer on a molecular level have led to the in...
