Epidermal growth factor and transforming growth factor alpha.
This review describes the discovery and initial characterization of the epidermal growth factors (EGFs) and transforming growth factors alpha (TGF alpha), the biosynthesis and tissue distribution of these molecules and a brief description of the effects of these molecules in culture and animals. An analysis of the similarities between the EGFs and TGF alpha s from different organisms is used to...
متن کاملEpidermal growth factor receptor and bladder cancer.
Muscle-invasive bladder cancer is a disease which causes significant morbidity and mortality. The two main forms of treatment for this disease include radical cystectomy and radical radiotherapy, but five year survival after treatment remains low at 40%. Many clinical and molecular risk factors have been shown to be associated with poor prognosis. One such factor is the expression of epidermal ...
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 کاملGenes for epidermal growth factor receptor, transforming growth factor alpha, and epidermal growth factor and their expression in human gliomas in vivo.
Anomalies of the epidermal growth factor receptor (EGFR) gene, including amplification, rearrangement, and overexpression, have been reported in malignant human gliomas in vivo. In vitro glioma cell lines coexpress EGFR and at least one of its ligands, transforming growth factor alpha, suggesting the existence of an autocrine growth stimulatory loop. We have studied the tumor tissue from 62 hum...
