ADAM Binding Protein Eve-1 Is Required for Ectodomain Shedding of Epidermal Growth Factor Receptor Ligands

Ectodomain Shedding of Epidermal Growth Factor Receptor Ligands Is Required for Keratinocyte Migration in Cutaneous Wound Healing

Keratinocyte proliferation and migration are essential to cutaneous wound healing and are, in part, mediated in an autocrine fashion by epidermal growth factor receptor (EGFR)-ligand interactions. EGFR ligands are initially synthesized as membrane-anchored forms, but can be processed and shed as soluble forms. We provide evidence here that wound stimuli induce keratinocyte shedding of EGFR liga...

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 ...

Assessment 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 ...

Ligand binding and dynamics of the monomeric epidermal growth factor receptor ectodomain

The ectodomain of the human epidermal growth factor receptor (hEGFR) controls input to several cell signalling networks via binding with extracellular growth factors. To gain insight into the dynamics and ligand binding of the ectodomain, the hEGFR monomer was subjected to molecular dynamics simulation. The monomer was found to be substantially more flexible than the ectodomain dimer studied pr...
