Genome-wide expressing profiling of nasopharyngeal carcinoma primary tumors versus non-cancerous nasopharyngeal tissues.

ABSTRACT: To explore differentially expressed genes between nasopharyngeal carcinoma (NPC) primary tumors and non-cancerous nasopharyngeal tissues, 18 NPC tissue samples versus 18 control samples were utilized to perform genome-wide expressing profiling. Consequently, 2992 genes were found to be differentially expressed in NPC tissues relative to the control (FC>2, P<0.05). Among these 2992 genes, uPA was ranked as the top one in all upregulated genes sorted by ascending order of P-value. Moreover, expression of uPAR was also upregulated in NPC tissues with FC=3.34 and P=7.52M-CM-^W105. 18 nasopharyngeal carcinoma primary tumors and 18 non-cancerous nasopharyngeal tissues were used to perform genome-wide expressing profiling. The median ages of patients were 46 (range, 19-77) for NPC patients and 45 (range, 18-78) for the non-cancerous cohort. Almost one third of patients were female. All samples were collected before any anti-cancer treatment.

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

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.

Genome-wide analysis of DNA methylation between nasopharyngeal carcinoma tissues and normal nasopharyngeal epithelial tissues

Project description:Nasopharyngeal carcinoma (NPC) is rare malignancy in most parts around the world but common in Southern China and Southeast Asia, Annually, approximately 80,000 new NPC cases and 50,000 deaths are reported worldwide. In NPC, recent advances have shown that many genes that are predominantly or even exclusively silenced by DNA methylation in epithelial cells during pathogenesis of NPC. However, the causal relationship between DNA methylation status and outcome in NPC remains not well understood. To investigate this problem, we used Illumina 450K BeadChips to examined methylation patterns and survival in NPC. and ultimately provided insight into prognostic value of DNA methylation in NPC clinical management. We employed Illumina Human Methylation450K Beadchip to analyze a genome-wide of DNA methylation in a cohort of 48 samples (between 24 nasopharyngeal carcinoma tissues and 24 normal nasopharyngeal epithelial tissues) to identify aberrant methylation genes.

serum microRNA profile of human nasopharyngeal carcinoma

Project description:To evaluate whether serum microRNAs can predict survival in nasopharyngeal carcinoma (NPC) patients, we analyzed the serum microRNA expression profiles in 8 NPC patients with shorter-survival time and 8 age- and gender-matched NPC patients with longer-survival time using microarray. We identified a four-microRNA signature can predict survival of NPC patients. 8 serum samples from nasopharyngeal carcinoma patients with shorter-survival time and 8 serum samples from nasopharyngeal carinoma patients with longer-survival time

Systematic profiling of human microRNAs in plasma from nasopharyngeal carcinoma patients reveals candidate biomarkers

Project description:We used microarrays to perform systematic profiling of human microRNAs in plasma from nasopharyngeal carcinoma (NPC) patients to find potential biomarkers. By comparing the plasma microRNA profiles of the NPC patients and healthy donors, potential biomarkers for NPC were investigated.

Competitive Endogenous RNA Landscape in Epstein-Barr Virus Associated Nasopharyngeal Carcinoma

Project description:In this study, we investigated the role of microRNAs and circular RNAs in Nasopharyngeal Carcinoma (NPC) by constructing a circRNA-miRNA-mRNA co-expression network and performing differential expression analysis on mRNAs, miRNAs, and circRNAs. By comparing the expression profile of non-cancerous immortalized nasopharyngeal epithelial cell lines and NPC cell lines, we identified differentially expressed coding and non-coding RNAs. By leveraging coexpression and miRNA target prediction tools, we constructed a ceRNA network composed of mRNAs, miRNAs, and circRNAs.

Identification of novel Epstein-Barr Virus miRNA genes from Nasopharyngeal Carcinomas

Project description:MicroRNAs (miRNAs) represent a conserved class of small non-coding RNAs that are found in all higher eukaryotes as well as some DNA viruses. MiRNAs are 20-25 nucleotides (nt) in length and have important regulatory functions in biological processes such as embryonic development, cell differentiation, hormone secretion or metabolism. Furthermore, miRNAs have been implicated in the pathology of various diseases including cancer. MiRNA expression profiles not only classify different types of cancer but also may even help to characterize distinct tumor stages, therefore constituting a valuable tool for prognosis. Here we report the miRNA profile of Epstein-Barr Virus (EBV)-positive nasopharyngeal carcinoma (NPC) tissue samples characterized by cloning and sequencing. We find that all EBV miRNAs from the BART region are expressed in NPC tissues whereas ebv-miRNAs from the BHRF1 region are not found. Moreover, we identify two novel EBV miRNA genes originating from the BART region that have not been found in other tissues or cell lines before. We also identify three new human miRNAs, which might be specific for nasopharyngeal tissues. We further show that a number of different cellular miRNAs are upor down-regulated in NPC tissues compared to control tissue including miR-15a and miR-16. We find that the tumor suppressor BRCA-1 is a target of miR-15a as well as miR-16 suggesting a miRNA role in NPC pathogenesis. 2 pairs of NPC and control tissues from 2 patients (4 samples in total) were examined.
