Patterning of the Drosophila ventral epidermis is a tractable model for understanding the role of signalling pathways in development. Interplay between Wingless and EGFR signalling determines the segmentally repeated pattern of alternating denticle belts and smooth cuticle: spitz group genes, which encode factors that stimulate EGFR signalling, induce the denticle fate, while Wingless signallin...

The specification of distinct neural cell types in central nervous system development crucially depends on positional cues conferred to neural stem cells in the neuroectoderm. Here, we investigate the regulation and function of the epidermal growth factor receptor (EGFR) signalling pathway in early development of the Drosophila brain. We find that localized EGFR signalling in the brain neuroect...

BACKGROUND Activating somatic mutations in epidermal growth factor receptor (EGFR) confer unique biologic features to non-small cell lung cancer (NSCLC) cells, but the transcriptional mediators of EGFR in this subgroup of NSCLC have not been fully elucidated. METHODOLOGY/PRINCIPAL FINDINGS Here we used genetic and pharmacologic approaches to elucidate the transcriptomes of NSCLC cell lines. W...

conclusions we discovered a consistent reduction of serum ace levels by two oral antiviral monotherapies, entecavir and telbivudine. serum ace levels were negatively correlated with egfrs in telbivudine treated patients. objectives we aimed to investigate changes in serum protein abundances associated with renal function in response to antiviral treatments. materials and methods primarily, a tr...

PURPOSE We aimed to investigate the feasibility of droplet digital PCR (ddPCR) for the quantitative and dynamic detection of EGFR mutations and next generation sequencing (NGS) for screening EGFR-tyrosine kinase inhibitors (EGFR-TKIs) resistance-relevant mutations in circulating tumor DNA (ctDNA) from advanced lung adenocarcinoma (ADC) patients. RESULTS Detection limit of EGFR mutation in ctD...

Ezrin is a scaffolding protein that is involved in oncogenesis by linking cytoskeletal and membrane proteins. Ezrin interacts with epidermal growth factor receptor (EGFR) in the cell membrane, but little is known about the effects of this interaction on EGFR signaling pathway. In this study, we established the biological and functional significance of ezrin-EGFR interaction in non-small cell lu...

conclusions functional renal impairment in diseases caused by hcv was more important than in diseases caused by hbv. the egfr was statistically lower in cirrhosis secondary to hcv than in hcv chronic hepatitis. results hbv chronic hepatitis, hcv chronic hepatitis, and cirrhosis secondary to these viruses were associated with a reduction of the gfr. the egfr was higher in patients with hbv chron...

BACKGROUND EGFR, KRAS, and ALK alterations are major genetic changes found in non-small cell lung cancers (NSCLCs). Testing advanced lung adenocarcinoma tumors for these three genes is now standard care. The purpose of this study was to investigate the clinicopathologic expression pattern of these three genes in East Asian NSCLC patients. PATIENTS AND METHODS We conducted a retrospective stud...
