Altered 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 کاملThe epidermal growth factor-induced calcium signal in A431 cells.
Addition of epidermal growth factor (EGF) to human A431 cells causes a 2-4-fold increase in cytoplasmic free Ca2+ concentration ([Ca2+]i) as measured by quin-2 fluorescence. The EGF effect is rapid but transient: [Ca2+]i reaches a maximum within 30-60 s and then returns to its resting value (182 +/- 3 nM) over a 5-8-min period. The EGF-induced [Ca2+]i rise is completely dependent on extracellul...
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 کاملAssociation of the epidermal growth factor receptor kinase with the detergent-insoluble cytoskeleton of A431 cells
The epidermal growth factor receptor (EGF-R) on human epidermoid carcinoma cells, A431, was found to be predominantly associated with the detergent-insoluble cytoskeleton, where it retained both a functional ligand-binding domain and an intrinsic tyrosine kinase activity. The EGF-R was constitutively associated with the A431 cytoskeleton; this association was not a consequence of adventitious b...
متن کاملEffects of epidermal growth factor receptor concentration on tumorigenicity of A431 cells in nude mice.
To test the relationship between the concentration of epidermal growth factor (EGF) receptors and tumor growth in vivo, we measured the rate of growth of several independently isolated A431 cell lines in athymic mice. This series of A431 clonal variants with differing extents of EGF receptor gene amplification and protein expression were implanted into athymic mice and the time to solid tumor f...
