Chromatin accessibility changes caused by Phf6 deletion in Leukemia-initiating cells from the retroviral-HoxA9 AML mouse model [ATAC-Seq LICe]

ABSTRACT: Hematopoietic conditional knockout (cKO) of Phf6 in a mouse retroviral-HoxA9 AML model led to increased transplantability and accumulation of a c-Kit+ Ly6C- population that we termed the 'Leukemia Initiating Cell-Enriched' (LIC-e) population. We performed bulk ATAC-Seq on the LIC-e population sort purified 4 days after transduction of Ctrl (Vav-Cre/+, Phf6 +/Y) or cKO (Vav-Cre/+, Phf6 flox/Y) marrow retrovirally transduced with HoxA9.

Transcriptome changes caused by Phf6 deletion in Committed leukemic cells from the retroviral-HoxA9 AML mouse model [RNA-seq Committed leukemic cell]

Project description:Hematopoietic conditional knockout (cKO) of Phf6 in a mouse retroviral-HoxA9 AML model led to increased transplantability. We performed bulk RNA-Seq on the 'committed' population (c-Kit+, Ly6C+) sort purified from primary recipients of HoxA9-transduced Ctrl (Vav-Cre/+, Phf6 +/Y marrow transduced with HoxA9) and cKO cells (Vav-Cre/+, Phf6 flox/Y marrow transduced with HoxA9) 8 weeks after transplantation. Our results reveal that Phf6 deletion has minimal effects on the transcriptome of the committed population (see separately deposited series for effects on the transcriptome of leukemia initiating [LIC-e] cells).

MicroRNA-155 is upregulated in Hoxa9/Meis1 leukemia inducing cells but is dispensable for in vivo transformation and leukemia development

Project description:OBJECTIVE: The microRNA miR-155 is upregulated in Hoxa9 and Meis1 leukemia inducing cells (LIC) , and miR-155 accelerates the onset of acute myeloid leukemia (AML) together with Hoxa9 but through largely unknown molecular mechanisms. The impact of miR-155 on accelerated onset of leukemia in the context of Hoxa9 and Meis1 is also unclear. To further resolve this, we performed a gene expression profiling, in the context of Hoxa9 and Meis1 leukemogenesis with miR-155 knocked out. RESULTS: Gene expression profiling of Hoxa9/Meis1 LIC without miR-155 does not delay the onset of AML and the gene expression changes are small

PBX3 cooperates with MEISI in causing rapid acute myeloid leukemia and recapitulates the core transcriptome of MLL-rearranged leukemia

Project description:To investigate whether co-expression of PBX3/MEIS1 can mimic that of MLL-AF9, HOXA9/MEIS1 or HOXA9/PBX3 in inducing leukemogenesis, we conducted in vivo mouse bone marrow transplantation (BMT) assays. Briefly, normal mouse bone marrow (BM) progenitor (i.e., lineage negative; Lin-) cells collected from B6.SJL (CD45.1) donor mice (CD45.1) were retrovirally co-transduced with MSCVneo-MLL-AF9+MSCV-PIG (MLL-AF9), MSCVneo-HOXA9+MSCV-PIG (HOXA9), MSCVneo-HOXA9+MSCV-PIG-MEIS1 (HOXA9+MEIS1), MSCVneo-HOXA9+MSCV-PIG-PBX3 (HOXA9+PBX3), MSCV-PIG-PBX3+MSCVneo-MEIS1 (PBX3+MEIS1), MSCVneo+MSCV-PIG-PBX3 (PBX3) , MSCVneo+MSCV-PIG-MEIS1 (MEIS1), or MSCVneo+MSCV-PIG (normal control; NC). Retrovirally transduced cells then were cultured with cytokines as well as puromycin and G418. Seven days later, the donor cells were transplanted into lethally irradiated (960 rads) 8- to 10-week-old C57BL/6 (CD45.2) recipient mice. The transplanted mice were watched for leukemogenesis. Then, gene expression profiling was conducted with bone marrow samples collected from leukemia groups and control group.

HOXA9 transcriptomic analysis in GBM cell lines (U87MG, U251 and primary GBML18) and in immortalized human astrocytes (hTERT/E6/E7)

Project description:Assess gene expression patterns upon HOXA9 ectopic expression in U87MG GBM cell line and hTERT/E6/E7 immortalized human astrocytes, and HOXA9 silencing in U251 and GBML18 GBM cell lines. U87MG and hTERT/E6/E7 were retrovirally-infected with an MSCV control vector (MSCV-Control) or with a construct containing the coding region of HOXA9 (MSCV-HOXA9), resulting in U87MG-Control, U87MG-HOXA9, hTERT/E6/E7-Control and hTERT/E6/E7-HOXA9 cell lines. GBML18 and U251 cells were transfected with HOXA9 gene-specific shRNA sequences (shHOXA9) or a non-efective shRNA (shControl) in pGFP-V-RS plasmid, resulting in U251-shControl, U251-shHOXA9, GBML18-shControl and GBML18-shHOXA9 cell lines. Four experimental replicates for HOXA9 overexpression cell lines, and three for HOXA9 silencing cell lines were performed.

Proteomic analysis of adult CNS from Rhoa cKOs and CTRs mice

Project description:Oligodendrocyte differentiation and subsequent myelination rely on strict regulatory mechanisms and molecules. Here we aimed at understanding the role of the Rho GTPase RhoA during oligodendrocyte differentiation and myelination in vivo. Using a conditional cell-specific ablation of Rhoa (Rhoa fl/fl mice crossed with Cnp-Cre mice) in oligodendrocytes, we show that RhoA controls the timing and progression differentiation and myelination. To identify putative mechanisms underlying the Rhoa cKO phenotype, we performed quantitative label-free LC-MS/MS proteomics on optic nerves from Rhoa cKO (Rhoa fl/fl Cre+) and control mice (Rhoa fl/fl Cre-) at 30 days post-birth (P30). Manual annotation of the differentially abundant proteins showed a large modulation of several proteins clusters associated with actin cytoskeleton, signal transduction and mitochondria.
