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

Project description:Nasopharyngeal carcinoma is an Epstein-Barr virus-associated epithelial cancer with high prevalence in Southeast Asia. mRNA expression levels were measured for essentially all human genes and all latent Epstein-Barr virus (EBV) genes in nasopharyngeal carcinoma tissue samples and normal nasopharyngeal tissues. Data were analyzed for differential gene expression between tumor and normal tissue and for correlations with levels of viral gene expression. Primary publications: Sengupta et al, 2006, Cancer Research 66(16): 7999-8006. Dodd et al, 2006, Cancer Epidemiology, Biomarkers & Prevention 15(11): 2216-2225. In subsequent studies using the same set of tissue samples, microRNA levels were measured in tumors and normal tissues and analyzed for correlations with differential target gene expression (Sengupta et al, 2008, Proc. Nat. Acad. Sci. USA 105: 5874-5878.) Experiment Overall Design: Total RNA extracted from laser-captured epithelium from 31 nasopharyngeal carcinomas and 10 normal healthy nasopharyngeal tissue specimens.

Project description:Epstein-Barr virus (EBV) has been etiologically linked to human malignancies including Nasopharyngeal Carcinoma (NPC). Although EBV-encoded miRNAs have been shown to contribute to viral latency, host cell survival and immune evasion, their direct impact on cancer progression in their human host remains unclear. In the current study, based on a miRNA expression profiling analysis of a larger number of clinical specimens using a miRNA array platform containing human, EBV and other species miRNA probes., we found that some EBV-miR-BARTs were highly expressed in NPC. Accordingly, further exploration of the potential roles and regulatory mechanisms of some important EBV-miR-BARTs in NPC progression was carried out. We applied a miRNA expression profiling analysis in 20 poor or undifferentiated NPC (Nasopharyngeal Carcinoma) matched with 20 benign chronic nasopharyngitis (CNP) specimens using a miRNA array platform containing human, EBV and other species miRNA probes. Two-group experiment, NPC vs CNP. Biological repelicates: 20 NPCs, 20 CNPs. One replicate per array.
