Structural basis for recognition of SMRT/N-CoR by the MYND domain and its contribution to AML1/ETO's activity

ABSTRACT: To examine the effects of disrupting the AML1/ETO MYND-SMRT interaction with the W692A substitution on AML1/ETO function, the global gene expression profile of mouse bone marrow LSK cells transduced with GFP was compared to that of cells transduced with either wild-type AML1/ETO or AML1/ETO harboring the W692A substitution in the MYND domain. Three independent biological replicates were assessed for both the control (GFP/MigR1) and AML1/ETO (intact MYND-SMRT interaction) conditions, whereas four independent biological replicates were assessed for the W692A (disrupted MYND-SMRT interaction) condition. The three GFP replicates were used to establish a baseline signal for comparison to both the AML1/ETO and W692A samples. Keywords: genetic modification

Transcription profiling of mouse bone marrow LSK cells transduced with wild type AML1/ETO or AML1/ETO harboring the W692A substitution in the MYND domain reveals a structural basis for recognition of SMRT/N-CoR by the MYND domain and its contribution to AML1/ETO activity

Experiment Overall Design: Global gene expression profiles of FACS-sorted Lin-Sca1+cKit+ mouse bone marrow cells transduced with empty vector (GFP-MigR1), AML1/ETO, or AML1/ETO with the W692A substitution (W692A).

MEIS2 is a novel oncogenic partner in AML1-ETO positive AML [Affymetrix]

Project description:MEIS2 collaborates with AML1-ETO in inducing acute myeloid leukemia in a murine bone marrow transplantation model We compared Gene expression profile (GEP) of murine bone marrow cells transduced with GFP, AML1-ETO, MEIS2, and AML1-ETO/MEIS2. Data from MEIS1 and AML1-ETO/MEIS1 is also included. Mouse bone marrow cells were kept in culture for 48hrs after retroviral transduction. GFP positive cells were then sorted and cells were kept for further 24 hours in culture before microarray analysis.

CUT&RUN of AML1-ETO binding occupancy following miR-130a KD in Kasumi-1 cells

Project description:We performed CUT&RUN assay with control Ig , anti-Flag and anti-ETO antibodies in Flag-tag AML1-ETO Kasumi-1 cells to determine binding occupancy of AML1-ETO following miR-130a KD. Kasumi-1 cells were transduced in 3 independent replicates for control and miR-130a KD samples with lentiviruses containing GFP reporter gene. GFP+ cells were sorted 3 days post-transduction and the cells were used in the CUT&RUN assay. Three antibodies were used for each biological sample.

Genome-wide co-occupancy of AML1-ETO and N-CoR defines the t(8;21) AML signature in leukemic cells

Project description:This study characterizes the genome-side occupancy of AML1, AML1-ETO and the cofactors N-CoR and p300 in leukemics cells (Kasumi-1) to discover novel regulatory mechanisms involving genes bound by the t(8:21) fusion protein AML1-ETO. A significant discovery of our study is the co-localization of AML1-ETO with the N-CoR co-repressor on genomic regions that are primarily distal to the transcriptional start sites (TSSs). These regions exhibit over-representation of the PU.1 motif: PU.1 is a key hematopoietic regulator and member of the ETS family of transcription factors. Functionally, genes co-occupied by AML1-ETO and N-CoR (e.g., TYROBP and LAPTM5) are associated with the leukemic phenotype, as determined by analyses of gene ontology and by the observation that these genes are predominantly up-regulated upon AML1-ETO depletion. To further probe the regulatory context of these leukemic cells, genome-wide enrichment of the transcriptional initiation-associated histone modification H3K4me3 was also measured.

AML1/ETO, AML1, and HEB binding patterns on chromosme 19

Project description:Approximately 20% of Acute Myelogenous Leukemia (AML) cases carry the t(8;21) translocation, which involves the AML1 and ETO genes, and express the resulting AML1/ETO fusion protein that functions as a transcriptional repressor by recruiting NCoR/SMRT/HDAC complexes to DNA. We used ChIP-chip to identify the determinants of AML1/ETO binding on a contiguous DNA region (chromosome 19). AML1/ETO binding regions are characterized by a specific sequence signature that includes the presence of the consensus binding sites for the AML1 and HEB transcription factors. We therefore assessed the binding patterns of AML1 and HEB on chromosome 19. A specific chromatin modification (tri-methylation of lysine 4 on histone 3 = 3MetK4) was also studied in U937 cells expressing AML1/ETO in order to correlate the identified binding profiles with active transcription sites. Keywords: ChIP-chip
