Project description:Gastric cancer is one of the most common cancers worldwide. Epstein-Barr virus-associated gastric cancer accounts for approximately 10% of all gastric cancers. EBV expresses its own proteins and miRNAs (BART miRNAs) and regulates host gene expression. In this study, we examined the effect of EBV infection on host mRNA expression. Differential gene expression was analyzed between EBV-negative human gastric cancer cell line AGS and EBV-positive human gastric cancer cell line AGS-EBV.

Project description:Gastric cancer is one of the most common cancers worldwide. Epstein-barr virus-associated gastric cancer accounts for about 10% of all gastric cancers. EBV itself expresses a variety of proteins and regulates the expression of host genes. In this study, we examined the knockdown of BC200 and eIF4A3 in AGS-EBV, respectively, and analyzed its effect on host mRNA expression.

Project description:EBV-positive cell lines were assayed for expression of EBV miRNAs. The names of the miRNAs are from miRBase from Fall 2007. Microarray probes are tandem complements of the mature miRNA sequence. We assayed Burkitt's lymphoma (BL), Nasopharyngeal carcinoma, post-transplant lymphoproliferative disease (PTLD), primary effusion lymphoma, and lymphoblastoid cell lines. We also assayed primary B cells that were infected with the B95-8 strain of EBV, which was found to express EBV miRNAs as early as 20 hours post infection. We have found PTLD and BLs from HIV-positive donors both express EBV miRNAs. These types of cell lines have not previously been found to express viral miRNAs. We have found that cells that support type I and type II latency express only the BART miRNAs, whereas cells that support type III latency express BART and BHRF1 miRNAs. Furthermore, BL cell lines that spontaneously lose EBV express levels of the viral miRNAs that are at least 5-fold lower than cell lines that do not lose EBV. In total, 48 samples have been assayed and included in this study. EBV-negative control samples are not included in this data set, but raw and processed data may be requested from the contributors. These EBV-negative cell lines include the Burkitt's lymphoma cell lines, BJAB and Akata-negative, the gastric carcinoma cell line, AGS, and uninfected primary B cells. Of the 48 samples, we have assayed 22 different EBV-positive cell lines and 4 different time points after infection of primary B cells with EBV. Replicates of the majority of cell lines is included in this data set. Replicates are from independent RNA isolations that were then hybridized to individual microarrays.

Project description:The aim of this experiment was analyze the genes regulated by self-released extracellular ATP in gastric cancer-derived cell line AGS, for this we incubate the cells by 48h with apyrase, a potent ectonucleotidase thta hydrolyze the extracellular ATP to form ADP and AMP. Then cDNA microarray were performed using a human cancer library.

Project description:Purpose: Evaluation of the m6A modification of EBV and BJAB transcripts during EBV infection Methods: Human B lymphoma cell line BJAB was uninfected or infected with EBV for 24 hours. Total RNA from each sample were extracted. Intact mRNA was isolated from total RNA samples and then chemically fragmented to 100-nucleoside-long fragments. m6A methylated mRNAs were immunoprecipitated with anti-N6-methyadenosine (m6A) antibody (a part of the fragmented mRNAs was kept as input). Both m6A enriched mRNAs and input mRNAs were concentrated for RNA-seq library construction. Sequencing was performed using an Illumina HiSeq 4000. Results: EBV EBNA2 and BHRF1 transcripts were m6A modified and m6A modification of BJAB transcripts changed during EBV infection. Conclusions: Our study found that some EBV transcripts were m6A modified during EBV infection and EBV infection changed m6A modification profiles of BJAB transcripts.

Project description:Beta-catenin (CTNNB1) is a major component of Wnt signaling pathway and a crucial player in gastric cancer. To delineate the complex transcription program governed by CTNNB1 in gastric cancer cells, CTNNB1 was silenced in AGS, a commonly used Wnt signaling activated gastric cancer cell line and the resultant changes in genome-wide mRNA expression pattern was profiled using Affymetrix Human Gene 1.0 ST Array.
