Project description:PacBio sequencing was performed to identify alternative splice patterns of Cp/Wp-driven transcripts. We were particularly interested in splicing from Cp/Wp exons to the HF exon. The HF exon contains pri-miR-BHRF1-2 and 1-3, so splicing to the HF exon would indicate that these pri-miRNAs are capable of regulating the 5' EBNA-LP ORF in cis through excision by Drosha.
Project description:Epstein-Barr virus (EBV) is able to drive the transformation of B-cells, resulting in the generation of lymphocyte cell lines (LCLs) in vitro. EBV nuclear proteins EBNA3A and EBNA3C are necessary for efficient transformation, while EBNA3B is dispensable. We describe a transcriptome analysis of LCLs generated with EBNA3B knockout (3BKO) EBV (made in the B95-8 BAC generated by Delecluse and Hammerschmidt) and comparable LCLs made with the parental B95-8 BAC (wtBAC).<br>Peripheral blood cells from three donors were infected with two 3BKO virus preparations, and two wtBAC virus preps. LCLs were grown out, and RNA extracted after 3-6 weeks (depending how long the outgrowth took). Total RNA was ribominus treated and then labelled and hybridised to Affymetrix human exon 1.0ST microarrays.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:SPO11-promoted DNA double-strand breaks (DSBs) formation is a crucial step for meiotic recombination, and it is indispensable to detect the broken DNA ends accurately for dissecting the molecular mechanisms behind. Here, we report a novel technique, named DEtail-seq (DNA End tailing followed by sequencing), that can directly and quantitatively capture the meiotic DSB 3’ overhang hotspots at single-nucleotide resolution.
Project description:Asthma is a chronic inflammatory airway disease characterized by airway inflammation and remodeling. The role of 15-oxo-5Z,8Z,11Z,13E-eicosatetraenoic acid (15-oxoETE), a 15-HETE metabolite catalyzed by 15-prostaglandin dehydrogenase (15-PGDH), has been relatively unexplored in asthma. In this study, we used RNA-seq to explore the effect of 15-KETE on the transcriptome of airway epithelial cells, aiming to identify its potential downstream targets and mechanisms of action.
