Immunohistochemical Evaluation of P53 and Epidermal Growth Factor Receptor Proteins Expression Levels in Gingival Tissue of Opium-dependent Patients
Background: Although evidence indicates that tobacco use is one of the risk factors for oral cancer, the relationship between opium addiction and oral cancer has not yet been evaluated. The present study was performed aiming to evaluate P53 and epidermal growth factor receptor (EGFR) expression in the gingival tissue of opium-dependent patients.Methods: 102 individuals (70 men and 32 women) wer...
متن کاملSulindac metabolites induce proteosomal and lysosomal degradation of the epidermal growth factor receptor.
The epidermal growth factor receptor (EGFR) is a member of the ErbB family of receptor tyrosine kinases. In response to ligand, EGFR is internalized and degraded by the ubiquitin-proteasome/lysosome pathway. We previously reported that metabolites of the nonsteroidal anti-inflammatory drug sulindac downregulate the expression of EGFR and inhibit basal and EGF-induced EGFR signaling through extr...
متن کاملCbl-b-dependent coordinated degradation of the epidermal growth factor receptor signaling complex.
Cbl proteins function as ubiquitin protein ligases for the activated epidermal growth factor receptor and, thus, negatively regulate its activity. Here we show that Cbl-b is ubiquitinated and degraded upon activation of the receptor. Epidermal growth factor (EGF)-induced Cbl-b degradation requires intact RING finger and tyrosine kinase binding domains and requires binding of the Cbl-b protein t...
متن کاملPhospholipase D is Dispensable for Epidermal Growth Factor-Induced Chemotaxis.
α-Synuclein (α-Syn) is implicated in several neurodegenerative disorders, including Parkinson's disease, known collectively as the synucleinopathies. α-Syn is known to be secreted from the cells and may contribute to the progression of the disease. Although extracellular α-Syn is shown to impair platelet-derived growth factor-induced chemotaxis, molecular mechanism of α-Syn-induced motility fai...
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 ...
