DNA Methylation is stable after MMEJ and NHEJ double strand break repair - OCI-AML3 dataset

Project description:DNA double strand breaks (DSBs) are a major source of mutations. Both non-homologous-end-joining (NHEJ) and microhomology-mediated-end-joining (MMEJ) DSB repair pathways are error prone and produce deletions, which can lead to cancer. DSBs also lead to epigenetic changes, including demethylation, which is involved in carcinogenesis. Of specific interest is the MMEJ repair pathway, as it requires methylation restoration around the break, as a result of the resection and formation of single stranded (ssDNA) intermediates. While, methylation patterns after homologous recombination (HR) have been partially studied, the methylation status after MMEJ and NHEJ remains poorly reported, and can be relevant for cancer. To study methylation patterns around DSB after NHEJ and MMEJ repair, we used targeted bisulfite-sequencing (BS-seq) to quantify methylation of dozens of single cell clones after induction of DSB by CRISPR. Each single cell clone was classified according to the sequence signature to a specific repair mechanism: NHEJ or MMEJ. Comparison of single cell clones after DSB to control cells, without DSB, demonstrated correct restoration of the methylation levels. No difference in methylation patterns was noticed when comparing NHEJ to MMEJ. Methylation levels in gene body, highly methylated CpGs (n=61, 4000 base pairs around DSB) and in low methylation CpGs (n=19), remained stable after both MMEJ and NHEJ. Gene body methylation persisted even on the background of DNMT3A R882C mutation, the most prevalent preleukemic mutation, in which the de novo methylation machinery is compromised. An exception observed in a single CpG site (ASXL1 995) which demonstrated elevated methylation rate after DSB repair only in the presence of WT DNMT3A. In summary, DNA methylation restoration demonstrated high fidelity after DSB both in methylated and unmethylated gene body, even in cases where DNA resections and deletions occurred.

RNA-seq expression profiling of OCI-AML2 and OCI-AML3 cells upon CRISPR/Cas9 –mediated disruption of DDX3X RNA binding domain

Project description:Human acute myeloid leukemia cell lines OCI-AML2 and OCI-AML3 were used in a CRISPR/Cas9-mediated approach to specifically target DDX3X’s gene sequences encoding the RNA binding domain of the helicase. DDX3X RNA binding domain is bipartite in the two halves of the helicase core. sgRNAs were designed to target both halves of the domain (named RNA binding domain A and B – RBDA and RBDB). We performed RNA-seq to observe the gene expression changes in both OCI-AML2 and OCI-AML3 cell lines following the not-combined CRISPR/Cas9 –mediated targeting of both regions of the DDX3X RNA binding domain. Control CRISPR/Cas9 performed with no sgRNA expressing vector (named “empty vector”) was performed in both cell lines. The latter condition was used as a control for gene expression changes analysis, for each cell line.

In vivo effects of localization and/or CXCR4 inhibition on gene expression profiles of OCI-AML3 cells

Project description:OCI-AML3, a human acute myeloid leukemia cell line, was inoculated into NOD/SCID/IL-2rγnull (NSG) mice. After engraftment and leukemic expansion were documented, mice were divided into 3 groups: control, or treatment for 24 or 72 hours with daily injections of LY2510294, a CXCR4-inhibitory peptide. OCI-AML3 cells were isolated from peripheral blood (PB), bone marrow (BM), or spleen (SP) for gene expression profiling (GEP).

Effect of omipalisib on transcriptome and signaling pathways in leukemic cell line OCI-AML3

Project description:To identify molecular effects of the dual PI3K/mTOR inhibitor omipalisib (GSK2126458), we applied gene expression profiling in human leukemic cell lines OCI-AML3 using Whole Transcriptome Shotgun Sequencing (RNA-seq). After OCI-AML3 cell were treated with 50 nM omipalisib for 24 h, differentially expressed genes (DEGs) of 1245 genes upregulated and 811 were downregulated were found compared with vehicle group. Down-regulated genes enriched in cell cycle, DNA metabolic process, PI3K/AKT/mTOR signaling, MYC pathway, E2F pathway, Gly, Ser and Thr metabolism, Cys and Met metabolism, carbon metabolism, oxidative phosphorylation, mitochondrial biogenesis and respiratory electron transporter chain.
