Expression data for human nasopharyngeal carcinoma cell line HK1 stimulated with EGF or TGF-β recombinant protein.

ABSTRACT: As regulators in gene expression, microRNAs take part in most biological process including cell differentiation, apoptosis, cell cycle and epithelial-to-mesenchymal transition (EMT). In order to evaluate their roles during the growth factors-induced EMT process, microRNA expression profile changes induced by EGF or TGF-β treatment on nasopharyngeal carcinoma cell line HK-1 cells were analyzed by means of the Affymetrix genome wide microarray system.

Expression data for human nasopharyngeal carcinoma cell line HK1 stimulated with EGF or TGF-Î² recombinant protein.

Project description:As regulators in gene expression, microRNAs take part in most biological process including cell differentiation, apoptosis, cell cycle and epithelial-to-mesenchymal transition (EMT). In order to evaluate their roles during the growth factors-induced EMT process, microRNA expression profile changes induced by EGF or TGF-Î² treatment on nasopharyngeal carcinoma cell line HK-1 cells were analyzed by means of the Affymetrix genome wide microarray system. Human nasopharyngeal carcinoma cell line HK-1 was starved for 12 hours before stimulation with EGF (50 ng/mL) or TGF-Î² (10ng/ml) or Control (PBS) for 36 hours in RPMI-1640 medium (with 1% serum) to establish the in vitro model of EMT. Total RNA were extracted and detected by AffymetrixÂ® GeneChipÂ® miRNA Arrays.

Gene Transcriptional Variation of Hepatic Progenitor Cells after TGF- 1-Induced EMT Transition and EGF-Induced MET Reversion

Project description:TGF-b1 induces hepatic progenitor cells experience an epithelial-mesenchymal transition, and EGF could reverse this process via mesenchymal-epithelial transition. Yet, the mechanism underline these EMT and MET processes are not clear. The aim of this study is to reveal the genes with significant difference during these EMT and MET process in hepatic progenitor cells.

microRNA profile of human nasopharyngeal tissues: nasopharyngeal carcinoma tissues vs. normal nasopharyngeal tissues

Project description:MicroRNAs are biomarkers of prognosis and survival for many types of cancer. We evaluated whether microRNAs can predict the survival and efficacy of concurrent chemotherapy in nasopharyngeal carcinoma (NPC) patients. We retrospectively analyzed microRNA expression in 312 paraffin-embedded NPC specimens and 18 normal nasopharyngeal tissues using microarray. We found Forty-one microRNAs are differentially expressed between NPC and normal tissues, and a five-microRNA signature can predict survival independent of stage. NPC patients with the low-risk microRNA signature have a favorable response to concurrent chemotherapy. microRNA profiling of nasopharyngeal carcinoma tissues vs. normal nasopharyngeal tissues 312 paraffin-embedded nasopharyngeal carcinoma tissues and 18 paraffin-embedded normal nasopharyngeal tissues

Microarray analysis of differentially expressed genes in bicalein-treated Nasopharyngeal carcinoma (HK-1) cell line

Project description:Baicalein is a bioactive compound that is found in an herbal plant, Oroxylum indicum, grown in Southeast Asia including Thailand. There are several reports investigating on the bioactivities of baicalein including an anticancer activity. However, there is no report on the anticancer activity of the baicalein in nasopharyngeal carcinoma. Thus, the aim of this study is to identify differentially expressed genes (DEGs) that are targets of baicalein in order to reveal cellular pathways and molecular mechanisms of the baicalein in nasopharyngeal carcinoma. In this study, NPC HK-1 cells were used as an NPC representative and treated with 10 and 20 µM baicalein for 24 hours before collecting cells for whole transcriptome profiles. The results revealed that a number of cellular pathways, based on KEGG enrichment analysis, are affected baicalein treatment such as focal adhesion and PI3K-Akt signaling pathway which were also phenotypically related to cell migration and invasion assays. Changes in transcriptome profiles of baicalein-treated HK-1 cells would provide insight on baicalein activity in NPC.

A Study of Lymphangiogenesis in Colorectal and Nasopharyngeal Cancer

Project description:1. To determine the association between LVD and clinico-pathologic variables in archived colorectal cancer and Nasopharyngeal carcinoma specimens 2. To determine the association between VEGF-C,-D expression with COX-2 expression and clinico-pathologic variables in colorectal cancer and Nasopharyngeal carcinoma 3. To determine the effect of celecoxib on lymphangiogenesis in Nasopharyngeal carcinoma Lymphangiogenesis and factors modulating lymphangiogenesis are associated with clinico-pathological outcome in Nasopharyngeal carcinoma and colorectal cancer. Celecoxib down-regulates lymphangiogenesis Archival colorectal cancer and Nasopharyngeal carcinoma tumor specimens will be obtained from the Department of Pathology. To determine the effect of celecoxib on lymphangiogenesis in Nasopharyngeal carcinoma, the investigators intend to analyze archived specimens collected in a previously conducted study. Colorectal tumor and nodal specimens and Nasopharyngeal carcinoma primary will be examined for MVD, LVD and growth factor expression using established haematoxylin and eosin and immunohistochemical techniques. Quantification of LVD and MVD shall be performed by two pathologists blinded to clinico-pathological variables using standardised methods.

EGF Induces Migration Independent of EMT or Invasion in A549 Lung Adenocarcinoma Cells

Project description:Tumors and tumor surrounding tissues produce multiple growth factors that influence tumor cell behavior via different signal transduction pathways. Growth factors like transforming growth factor beta (TGFβ) and epidermal growth factor (EGF) were shown to induce proliferation, migration and invasion in different cell models. Both factors are frequently overexpressed in cancer and will often act in combination. Although both factors are being used as rational targets in clinical oncology, similarities and differences of their contributions to cancer cell migration and invasion are not fully understood. Here we compared the impact of TGFβ, EGF and the combination of both factors on A549 cells. Both factors stimulated A549 migration to a similar extent but with a different kinetic and the combination had an additive effect. While EGF-induced migration depended on activation of the mitogen-activated protein kinase (MAPK) pathway, this pathway was dispensable for TGFβ-induced migration despite a strong activation by TGFβ. Proteome analysis revealed an overlap in expression patterns of migration-related proteins and associated gene ontology (GO) terms by TGFβ and EGF but only TGFβ induced the expression of epithelial to mesenchymal transition (EMT)-related proteins like matrix metalloproteinase 2 (MMP2). EGF in contrast, made no major contribution to EMT marker expression on either the protein or the transcript level. In line with these expression patterns, EGF was unable to increase invasion of A549 cells on its own and failed to enhance TGFβ-induced invasion. Overall, these data suggest that TGFβ and EGF may partly compensate each other for stimulation of cell migration but abrogation of TGFβ signaling may be more suitable for antagonizing invasion.

nasopharyngeal carcinoma versus nasopharyngeal phlogistic tissue reference

Project description:Nasopharyngeal carcinoma (NPC) remains a majoy health problem worldwide, specially in Southeast China. In order to find the new candidate genes and molecular markers that are associated with nasopharyngeal carcinoma (NPC), this study focused on the screening NPC relative genes by gene expression profile. Keywords: disease state analysis 23 NPC biopsies and 15 nasopharynx chronic phlogistic biopsies were used to screen NPC relative genes by BioStarH-141s (2004) profile gene chips which contained 14112 points of full length human genes. The tumor samples were labeled with Cy5-dUTP.The nasopharyngeal phlogistic tissues were labeled with Cy3-dUTP. Biostatistics and bioinformatics were also used to analyse the differently expressed genes.
