background: genes for human epidermal growth factor receptors b1 (erbb1) and b2 (erbb2) were amplified in breast and ovarian cancers. both of them were associated with aggressive disease and worse prognosis. the erbb1 or erbb2 status of a tumor may provide an indication of the response to erbb1 and erbb2 -targeted therapies. for accurate and rapid assessment of amplification of erbb1 and erbb2 ...
background and aims. many oral squamous cell carcinomas develop from potentially malignant disorders (pmds) which include a variety of lesions and conditions characterized by an increased risk for malignant transformation. this study evaluated the quantitative expression of egfr in normal oral mucosa, oral leukoplakia and oral submucous fibrosis to predict the malignant risk in compliance with ...

conclusions the her3 expression in developmental odontogenic cysts was higher than that in inflammatory odontogenic cysts. the higher rate of her3 expression in okc may justify inherent growth potential, stimulation-independent proliferation capability, invasive growth and high recurrence rate of the cyst accepted today as a tumor. results the her3 expression had positive results in 52.4% of ok...
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 ...

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 and sp...
introduction: growth, proliferation, survival, and differentiation are the prominent characteristics of cells, which are affected by cancer. epidermal growth factor receptor (egfr) plays a pivotal role in the effective control of these features. given the significance of egfr signaling pathway in non-small cell lung cancer (nsclc), egfr expression is influential on these cell characteristics. i...
