Project description:RNA-seq was used to characterize the LMP1 mediated regulation of host target gene regulation. We knocked out LMP1 in GM12878 Lymphoblastoid cell line (LCL). The GM12878 LCL expressing control sgRNA was used as the control.
Project description:The chromatin remodeller ATRX interacts with the histone chaperone DAXX, to deposit the histone variant H3.3 at sites of nucleosome turnover. ATRX is known to bind repetitive, heterochromatic regions of the genome including telomeres, ribosomal DNA and pericentric repeats many of which are putative G-quadruplex forming sequences (PQS). At these sites ATRX plays an ancillary role in a wide range of nuclear processes facilitating replication, chromatin modification and transcription. Here, using an improved protocol for chromatin immunoprecipitation, we show that ATRX also binds active regulatory elements in euchromatin. Mutations in ATRX lead to perturbation of gene expression associated with a reduction in chromatin accessibility, histone modification, transcription factor binding and deposition of H3.3 at the sequences to which it normally binds. In erythroid cells where down regulation of a-globin expression is a hallmark of ATR-X syndrome, perturbation of chromatin accessibility and gene expression occurs in only a subset of cells. The stochastic nature of this process suggests that ATRX acts as a general facilitator of cell specific transcriptional and epigenetic programmes, both in heterochromatin and euchromatin.
Project description:Here, we validate a novel protocol, Bulk RNA Barcoding and sequencing (BRB-seq), that combines the multiplexing-driven cost-effectiveness of a single-cell RNA-seq protocol with the efficiency of a bulk RNA-seq procedure. For this we first gauge the applicability of the SCRB-seq protocol on bulk DMSO and BAY treated human LCL, and compare its effectiveness as compared to TruSeq.
Project description:The aim was to identify the effect of caspase inhibition on changes in gene expression in MCF-7 cells induced by a combination of TRAIL and LCL-161. Treated samples and control samples were collected after 24 h of treatment.
