RNA-seq data of nasopharyngeal carcinoma (NPC) in non-endemic areas

ABSTRACT: Epstein-Barr virus (EBV) related nasopharyngeal carcinoma (NPC) is an epithelial malignancy with higher incidence in Asian endemic area (EA) than in non-endemic area (NEA), where frequency is below 1/105/year. The causes of such difference are unclear and might be related to viral, environmental (e.g. diet) and genomic factors. We aimed at dissecting the gene expression (GE) and microenvironment landscape in NPC leading to the identification of molecular subtypes explaining the differences between EA and NEA.

Methylome study in Nasopharyngeal Carcinoma (NPC)

Methylome study in Nasopharyngeal Carcinoma (NPC)

Project description:Aberrant methylation at the promoter region of tumor suppressors is frequently reported in NPC; however, genome-wide methylation changes have not been comprehensively investigated. Therefore, we systematically analyzed methylome data in 25 primary NPC tumors and non-tumor counterparts using Illumina HumanMethylation450 BeadChip. Bisulphite converted DNA from 50 samples were hybridized to the Illumina HumanMethylation450 BeadChip. Bisulphite pyrosequencing was used as an independent method to validate the BeadChip results.

NESG1-mediated differential expression genes in nasopharyngeal carcinoma (NPC)

Project description:Analysis of differential expression genes in NESG1-overexpressed and negative nasopharyngeal carcinoma. NESG1 is a candidate tumor suppressor in NPC. Results provide insight into the molecular pathogenesis of NESG1 in NPC. NESG1 cDNA was transfected into NESG1-negative NPC 5-8F cells and affymetrix microarrays HG-U133_Plus_2 were used to analyze the differential genes in NESG1-overexpressed NPC cells and their control NESG1-negative NPC cells.

Leukocytes methylome of individuals from leprosy endemic area

Project description:Inflammaging is the name given to this chronic and asymptomatic inflammatory state generated by the aging process and by chronic and infectious diseases. Chronic diseases can alter the epigenetic profile of tissues leading to an increased epigenetic aging and some of the differentially methylated genes can be used to characterize the disease and as disease biomarkers. Leprosy is an infection caused by Mycobacterium leprae and can be lifelong, exposing the individual to a low-grade inflammation environment. In this study, we evaluated the inflammatory profile in 35 individuals from a leprosy endemic area from Brazil by cytokine analysis with a luminex assay. In adition, we investigated the leucocytes genome-wide DNA methylation profile using the Infinium MethylationEPIC BeadChip array. A total number of 31 CpGs were significantly methylated, between cases and controls, which belonged to 8 genes potentially peripherally perturbed in the pathogenesis of the disease. Affected individuals from endemic area were epigenetically aged in relation to control samples and interesting control samples from endemic area were aged in relation to unaffected control samples from non-endemic area. In conclusion, leprosy showed a deregulated methylation profile in comparison with control samples. The epigenetic analysis provided valuable clues for further investigations in understanding peripherical blood leprosy alterations and the use of these genes as biomarkers.

Nasopharyngeal carcinoma (NPC)-derived exosomes reconstitute tumor microenvironment

Project description:Nasopharyngeal carcinoma is characterized by Epstein-Barr virus (EBV) infection and severe immune cell infiltration. Here, we explored the effect of tumor-derived exosomes on NPC microenvironment using single-cell RNA sequencing (scRNA-seq). We investigated the phenotypic and functional alterations in macrophages, as well as exosome-mediated cellular interactions. Human NPC biopsy samples were dissociated into single-cell suspension and stimuated with exosomes derived from an EBV positive cell line (HK1EBV) for 2 hours. A total of 14,446 qualified cells were subjected to analysis. Collectively, our findings revealed that NPC-derived exosomes facilitate immunosuppressive microenvironment and contribute to NPC progression.

Gene expression data of nasopharyngeal carcinoma (NPC) cell and Thiostrepton treatment

Project description:Thiostrepton, a natural antibiotic, has recently been shown to be a potential anticancer drug for certain cancers, but its study in nasopharyngeal carcinoma (NPC) is still limited. The aims of this study were to investigate the anticancer effect of thiostrepton on NPC cells and to explore its underlying mechanism. Our results showed that thiostrepton reduced NPC cell viability in a dose-dependent manner. Thiostrepton inhibited the migration and invasion of NPC cells in wound healing and cell invasion assays. Thiostrepton effectively suppressed NPC cell proliferation, migration, and invasion, likely by several mechanisms. Thiostrepton may be a potential therapeutic agent for treating NPC in the future.

miRNA-Seq profiling of nasopharyngeal carcinoma (NPC) and normal control samples

Project description:Epstein-Barr virus (EBV) is a ubiquitous human herpesvirus associated with nasopharyngeal carcinoma (NPC). EBV encodes two groups of microRNAs (miRNAs) which are divided into BamHI fragment H rightward open reading frame 1 (BHRF1) and BamHI-A rightward transcripts (BART) microRNAs. EBV miR-BARTs have been found to be involved in the development and progression of NPC. However, the role of EBV-miR-BARTs in NPC progression remains illusive. This study aimed to investigate the role of EBV-miR-BARTs in NPC and explore the underlying mechanisms.

Gene expression data of nasopharyngeal carcinoma (NPC) cell and Podoplanin (PDPN) siRNA treatment

Project description:Podoplanin, a transmembrane sialomucin-like glycoprotein, is now widely used as a marker for lymphatic endothelial cells and fibroblastic reticular cells in lymphoid organs, but its study in nasopharyngeal carcinoma (NPC) is still limited. The aims of this study were t characterize the role of PDPN in NPC. Our results showed that PDPN was expressed in most TW01 NPC cells. PDPN knockdown by siRNA decreased NPC cell proliferation, migration, and invasion. Knocking down PDPN results in suppression of NPC cell proliferation, migration, and invasion. PDPN may serve as a potential chemotherapeutic target for NPC treatment in the future.
