MeRIP sequencing analysis of BJAB cell line infected with EBV

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.

Gene expression profiling in wild-type, Irf5-KO, Lyn-KO and Lyn/Irf5-DKO BMDCs unstimulated or stimulated with CpG-B ODN

Project description:To characterize the relationship between IRF5 and Lyn in innate immune responses at a genome-wide scale, we performed gene expression microarray analysis for wild-type (WT), Irf5-KO, Lyn-KO and Lyn/Irf5-DKO bone marrow-derived dendritic cells (BMDCs) with or without 6 h-stimulation with 150 nM CpG-B ODN. We extracted the transcripts that were upregulated by CpG-B ODN in WT BMDCs, further upregulated in Lyn-KO BMDCs and then downregulated in Lyn/Irf5-DKO BMDCs (fold change ≥ 2, false discovery rate < 0.05). When these 79 transcripts were sorted by their expression levels in Lyn-KO BMDCs, most of the top 20 genes (13 out of 20) were those encoding type I interferons (IFNs), indicating that Lyn particularly suppresses IRF5 induction of type I IFNs.

We extracted the transcripts that were upregulated by CpG-B ODN in WT BMDCs, further upregulated in Lyn-KO BMDCs and then downregulated in Lyn/Irf5-DKO BMDCs (fold change â?¥ 2, false discovery rate < 0.05). When these 79 transcripts were sorted by their expression levels in Lyn-KO BMDCs, most of the top 20 genes (13 out of 20) were those encoding type I interferons (IFNs), indicating that Lyn particularly suppresses IRF5 induction of type I IFNs. BMDCs from WT, Irf5-KO, Lyn-KO and Lyn/Irf5-DKO mice in a C57BL/6 background were unstimulated or stimulated with CpG-B ODN. Biological triplicate for each genotype were analyzed (24 samples in total).

Global transcriptome analysis of BJAB cells that are modulated by EBV infection or (and) EBV BART6-3p mimics.

Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are using transcriptome profiling (RNA-seq) to evaluate the effects of EBV infection or (and) EBV BART6-3p mimics on the global transcriptome of the BJAB cells. Methods: BJAB cells were transfected with negative control mimics or BART6-3p mimics for 48 h and then infected with EBV virons for 2h. RNAs were extracted by Trizol and sequenced by Solexa high-throughput sequencing service (Oebiotech, Shanghai, China). Data were extracted and normalized according to the manufacturer’s standard protocol. Results: Log-fold changes of up- or down-regulated mRNAs between the control and experiment group were selected with a significance threshold of p<0.05. There are 408 mRNAs were up-regulated and 263 were down-regulated in “EBV infection” group cells comparing to “Mock” group cells. There are 385 mRNAs were up-regulated and 246 were down-regulated in “EBV infection + Bart6-3p mimics” group cells comparing to “EBV infection + negative control mimics” group cells. Conclusions: Our study describes the global transciptome changes of BJAB cells induced by EBV infection or (and) EBV 6-3p mimics.

BJAB Cell Lines Transduced with lentiviral vector pNL-SIN-CMV-AcGFP expressing KSHV miRNAs miR-K1, miR-K12-11, or miR-K4-3p

Project description:BJAB cells were infected with pNL-SIN-CMV-AcGFP (see accession number GSE8867 for data) or pNL-SIN-CMV-AcGFP expressing KSHV miR-K1, miR-K12-11 or miR-K4-3p and sorted 48 hours after infection. 12 or 16 days after transduction, cytoplasmic RNA was harvested and gene expression analysis of independent BJAB cell pools was performed using Human Operon v3.0.2 arrays. Each sample was run against Universal Human Reference RNA, Stratagene. The samples listed here were processed in parallel to those with accession number GSE8867, which includes all matched control cell lines.
