Project description:Epstein-Barr virus has been reported to regulate cellular microRNA expression in B cells. In the present study, we investigated the differential microRNAs modulated by Epstein-Barr virus in Naspharyngeal Carcinoma, using CapitalBio corporation's mammalian miRNA arrays. Three cellular models were used in this study: the human naspharyngeal carcinoma cell line TW03 as a blank control; TW03 transfected with Epstein-Barr virus encoded LMP1; TW03 transfected with Epstein-Barr virus encoded LMP2A
Project description:This SuperSeries is composed of the following subset Series: GSE10057: The Epstein-Barr Virus latent membrane protein 1 (LMP1) induces cellular microRNA146a GSE10105: Alteration of microRNA gene expression by EBV encoded LMP1 oncogene Keywords: SuperSeries Refer to individual Series
Project description:Gene expression profile of splenic B cells (CD19+) from transgenic mice expressing the Epstein-Barr virus (EBV) latent membrane proteins (LMP) 1 and/or LMP2A. Freshly harvested primary B cells were profiled. B lymphocytes from transgenic LMP1, LMP2A, LMP1/2A mice and negative littermates were profiled from 6 month old adult mice; lymphoma cells were passaged in SCID mice and profiled for three LMP1 positive lymphomas and one negative lymphoma.

Freshly harvested primary B cells were profiled. B lymphocytes from transgenic LMP1, LMP2A, LMP1/2A mice and negative littermates were profiled from 6 month old adult mice; lymphoma cells were passaged in SCID mice and profiled for three LMP1 positive lymphomas and one negative lymphoma. 12 total samples. 4 transgenic B lymphocyte samples pooled from multiple biological replicates were hybridized to duplicate microarrays: LMP1 (pooled from 2 replicates), LMP2A (pooled from 3 replicates); LMP1/2A (pooled from 5 replicates), negative littermates (pooled from 4 replicates). 3 biological replicates of LMP1 lymphomas expressing high, medium and low levels of LMP1 and; 1 negative lymphoma was hybridized to 1 microarray chip. The reference sample consisted of 4 biological replicates of splenic B cells (CD19+) pooled from 4-7 month old non-transgenic Balb/c mice. The same reference was used for all hybridizations.
Project description:Gene expression profile of AGS gastric carcinoma cell line infected in vitro with Epstein-Barr Virus. Some samples also contain are stably transfected with a dominant negative LMP1 construct.
Project description:Comparsion of cellular gene expression between a control B lymphoma cell-line (BJAB pz2) stably transfected with an empty vector and a BJAB cell-line stably expressing Epstein-Barr virus EBNA 3C (BJAB E3C-4). These cell lines are described in Wang, F., C. Gregory, C. Sample, M. Rowe, D. Liebowitz, R. Murray, A. Rickinson, and E. Kieff. 1990. Epstein-Barr virus latent membrane protein (LMP1) and nuclear proteins 2 and 3C are effectors of phenotypic changes in B lymphocytes: EBNA-2 and LMP1 cooperatively induce CD23. J Virol 64:2309-2318)
Project description:Latent infection with Epstein-Barr virus (EBV) is recognised as a factor in the pathogenesis of nasopharyngeal carcinoma (NPC). We found that EBV encoded Latent membrane protein 2A (LMP2A) enhances lipid accumulation significantly in NPC cells. We used microarrays to identify differential genes regulated by LMP2A in NPC cell lines.
Project description:Epstein-Barr virus is associated with several human malignancies, including Burkitt Lymnphoma. The virus encodes more than 40 microRNAs, which participate in its possible pathogenetic role. We used microarrays to study the effect of the expression of an Epstein-Barr virus-encoded microRNA (ebv-BART6-3p) on the global gene expression profile of Burkitt Lymphoma cell lines.
