Project description:The goal of this study was to determine IGF2BP3 RNA targets in human B-cell Acute Lymphocitic Leukemia cell models. Included are iCLIP-seq libraries for IGF2BP3 from RS4;11 and REH B-ALL cell samples and RNA-seq data sets from control and IGF2BP3 knockdown RS4;11 B-ALL cell lines
Project description:Transcriptional profiling of human acute lymphoblastic leukemia cell lines RS4;11: compare untreated RS4;11 with RS4;11 treated with VE-465. The goal was to determine the effects of VE-465 on global gene expression in RS4;11.
Project description:Transcriptional profiling of human acute lymphoblastic leukemia cell lines RS4;11: compare untreated RS4;11 with RS4;11 treated with VE-465. The goal was to determine the effects of VE-465 on global gene expression in RS4;11. VE-465 induced gene expression in RS4;11 was measured at 48 hours after exposure to doses of 0 and 200 nM VE-465. Three independent experiments were performed.
Project description:The acute lymphoblastic leukemia cells lines JM-1, REH, Nalm-27, and SUP-B15 were analyzed for baseline expression of extacellular matrix and adhesion molecules using a pathway focused cDNA microarray (SABiosciences). RNA isolated from the ALL cell lines JM-1, REH, Nalm-27, and SUP-B15 was analyzed using the Extracellular Matrix and Adhesion Molecules Oligo GEArray (SABIosciences).

Project description:MLL-fusion proteins are potent inducers of cancer in hematopoietic cells, where they are known to cause changes in global gene expression. How MLL-fusion proteins interact with the genome has not been established, so we have limited understanding of the pathway by which these proteins generate aberrant gene expression programs. Here we describe how the MLL-AF4 protein occupies the genome in human leukemia cells and its striking effects on chromatin states. We find that the MLL-AF4 fusion protein selectively occupies regions of the genome that contain developmental regulatory genes important for hematopoietic stem cell identity and self-renewal. These MLL-AF4 bound regions have grossly altered chromatin structure, with histone modifications catalyzed by Trithorax Group (TrxG) proteins and Dot1 extending across unusually large domains. This indicates that a key feature of MLL-associated leukemogenesis is aberrant targeting of chromatin modifiers to regions of the genome controlling hematopoietic development. Our results define the direct targets of the MLL-fusion protein, reveal the global role of epigenetic misregulation in leukemia, and identify new targets for therapeutic intervention in human cancer. This dataset includes expression data for two replicates each of SEM and REH leukemia cell lines, ChIP-chip data targeting RNAP2, H3K4me3, H3K79me2, ENL, AF4-C, and MLL-N in SEM and REH leukemia cell lines, and ChIP-Seq data of H3K79me2, H3K4me3, ans WCE in SEM and REH cell lines. This Series contains the ChIP-Seq data only. The expression and ChIP-chip data are provided in GEO Series GSE13313.
Project description:This study characterized the effect of WEE1 kinase inhibition using AZD1775 treatment on single-cell gene expression profile using the 10x Genomics protocol in the acute lymphoblastic leukemia cell lines RS4;11 (KMT2A-rearranged subtype) and Nalm6 (other subtype).
Project description:We report that retention of intron 2 which affects expression of CD19 in CART-19 relapsed leukemia occurs in the context of full length CD19 transcript using Oxford Nanopore sequencing technology. By performing Direct RNA sequencing on Reh leukemia cell lines, we showed that intron 2 retention is functionally equivalent to nonsense mutations.
Project description:Genomewide gene expression analysis of lymphoid cell lines of Hodgkin, non-Hodgkin and acute leukemia origin Affymetrix U133 Plus 2.0 oligonucleotide arrays were hybridized to determine the gene expression profile of Hodgkin (L428, L1236, KM-H2, HDLM-2, L540, L540Cy), non-Hodgkin (Namalwa, SU-DHL-4) and acute lymphoblastic leukemia (Reh) cell lines; all hybridizations were done in biological duplicates (except L540, L50Cy, SU-DHL-4).
