Project description:ChIP-seq analysis was performed in primary NKTL (Natural killer T-cell lymphoma) samples, normal tonsil samples and 2 cell lines to analyze acetylation of histone H3K27ac.
Project description:RNA-seq analysis was performed in primary NKTL (Natural killer T-cell lymphoma) samples and healthy tonsil samples to analyze gene expression changes in lymphoma sample.
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. 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:RNA-seq was used to characterize the LMP1 TES domain-mediated regulation of B-cell genome wide target genes. We created an inducible stable EBV-negative BL41 Burkitt Lymphoma cell line expressing LMP1 wildtype, TES1 functional only, TES2 functional only and TES1/2 non-functional. wildtype EBV-negative BL41 (no LMP1 transgene) cells were also subjected to CD40L (recombinant CD40 ligand) to study the B-cell target gene regulation in comparison to LMP1 wildtype-mediated.
Project description:Vitamin D deficiency has been associated with decreased overall survival in patients with diffuse large B-cell lymphoma treated with rituximab. Natural killer cell-mediated antibody-dependent cytotoxicity is one of the main mechanisms of action of rituximab, and it has been shown to be enhanced after in vivo vitamin D supplementation. We aimed to explore molecular mechanisms behind these findings using whole transcriptome analysis of natural killer cells after vitamin D supplementation
Project description:We have used microarray profiling to examine the expression of viral microRNAs (miRNAs) in two independently derived nasal natural killer T cell lymphoma (NKTCL) cell lines, SNK6 and SNT16. The goal of the study was to investigate the role of the viral miRNAs in the genesis and maintenance of NKTCLs.
Project description:RNA-seq was used to characterize the LMP1 TES domain-mediated regulation of B-cell genome wide target genes. We created an inducible stable EBV-negative Akata Burkitt Lymphoma cell line expressing LMP1 wildtype, TES1 functional only, TES2 functional only and TES1/2 non-functional.
Project description:We performed a comprehensive genome-wide miRNA expression profiling (MEP) of extranodal nasal-type Natural Killer/T-cell lymphoma (NKTL) using formalin fixed paraffin-embedded tissue (FFPE) (n=30) and NK cell lines (n=6) in comparison with normal NK cells, with the objective of understanding the pathogenetic role of miRNA deregulation in NKTL.
