Project description:Differential gene expression in RNA isolated from stably-transfected EBERs-negative versus EBERs-positive HK1 cell lines We established stable transfection of EBERs in the EBV-negative NPC cell line, HK1,to elucidate the role of the EBERs in NPC pathogenesis. Microarray gene expression profiling was carried out to investigate candidate genes which expression correlates with the expression of the EBERs.

Microarray gene expression profiling was carried out to investigate candidate genes which expression correlates with the expression of the EBERs. Total RNA was extracted from each cell line and processed using GeneChip® Whole Transcript (WT) Sense Target Labelling Assay and then analyzed with GeneChip® Human Gene 1.0 ST Array, with three repeats. Candidate genes differentially expressed between the two transfected HK1 cell lines were identified using GeneSpring GX 10 (Agilent Technologies).

Project description:Nasopharyngeal carcinoma (NPC) is a prevalent malignancyt disease in Southeast Asia among the Chinese population. Aberrant regulation of transcripts has been implicated in many types of cancers including NPC. Herein, we characterized mRNA and miRNA transcriptomes by RNA sequencing (RNASeq) of NPC model systems. Matched total mRNA and small RNA of undifferentiated Epstein-Barr virus (EBV)-positive NPC xenograft X666 and its derived cell line C666, well-differentiated NPC cell line HK1, and the immortalized nasopharyngeal epithelial cell line NP460 have been sequenced by Solexa technology.

Project description:Nasopharyngeal carcinoma (NPC) is enedemic in Southeast Asia but is uncommon worldwide. In Hong Kong, approximately 95% of NPC cases are associated with Esptein-Barr Virus (EBV). EBV has been shown to induce changes in the epigenetics of EBV-malignancies. Epigenetics in NPC may thus play an important role in NPC pathogensis. We performed targeted bisulfite sequencing to accurately profile the methylation changes in NPC and investigate the role of abberant methylation pattern in NPC.

EBV has been shown to induce changes in the epigenetics of EBV-malignancies. Epigenetics in NPC may thus play an important role in NPC pathogensis. We performed whole-genome bisulfite sequencing (WGBS) to profile the methylation changes in NPC and investigate the role of abberant methylation pattern in NPC.

Project description:To identify the difference of lytic infection by estradiol and TPA+SB in human nasopharyngeal carcinoma, EBV-positive nasopharyngeal cell line (HK1-EBV-eGFP) were subjected to RNA-seq analysis.

Project description:The NPC cell line C666_1 is known to be infected with Epstein Barr virus (EBV), and to have high expression of SSTR2A. The cell line was treated with PENN221 (an SSTR2A targeted drug conjugate) , Belinostat (a histone deacetylase inhibitor), DMSO (negative control) or left untreated (negative control). Both PENN221 and Belinstat resulted in increased cell death of the cell line. Treated samples were sequenced at 24h and 72h post treatment.

Project description:<p>Nasopharyngeal carcinoma (NPC) is an aggressive head and neck cancer characterized by Epstein-Barr virus (EBV) infection and dense lymphocyte infiltration. The scarcity of NPC genomic data hinders the understanding of NPC biology, disease progression, and rational therapy design. Here, we performed whole-exome sequencing (WES) on 111 micro-dissected EBV-positive NPCs, with 15 cases subjected to further whole-genome sequencing (WGS), to determine its mutational landscape. We identified enrichment for genomic aberrations of multiple negative regulators of the NF-kB pathway in a total of 41% of cases including CYLD, TRAF3, NFKBIA and NLRC5. Functional analysis confirmed novel inactivating CYLD mutations as drivers for NPC cell growth. The EBV oncoprotein latent member protein 1 (LMP1) functions to constitutively activate NF-kB signaling, and we observed mutual exclusivity among somatic NF-kB pathway aberrations and LMP1-overexpression, suggesting that NF-kB activation is selected for by both somatic and viral events during NPC pathogenesis.</p>
