Project description:Expression data from xenograft in BALB/c 6-wk-old nude mice with PC3 prostate cancer cells stably expressing PML or a vector control after treatment of the mice with palbociclib (100mg/kg/day diluted in sodium lactate 50mM pH4 given by gavage) during 5 consecutive days PML plays a role in the senescence tumor suppressor response of normal cells to oncogenic stress. PML also mediates therapy-induced senescence in acute promyelocytic leukemia cells after treatment with retinoic acid. However, many tumor cell lines fail to engage a complete senescence response to PML activation. Interestingly, in vivo and in vitro combination of PML overexpression with CDK inhibition induce senescence in PC3 prostate cancer cells. We used microarray to characterize the gene expression profile of PC3 stably expressing PML or a control vector after subcutaneous injection in BALB/c 6-wk-old nude mice and treatment of the mice with palbociclib (100mg/kg/day) during 5 consecutive days.. PC3 cells were infected with a retroviral vector that express PML or an empty vector before subcutaneous injection of 10^6 cells in both flanks of BALB/c 6-wk-old nude mice. Then, mice were treated for 5 consecutive days with palbociclib (100mg/kg/day diluted in sodium lactate 50mM pH4 given by gavage)

Project description:Ubiquitin-mediated proteolysis play a significant role in various biological processes including transcription, DNA repair and cell cycle progression. The identification of Set8 and Set8b (a splice isoform) histone H4K20 methyl transferase as a substrate for the cullin-based ubiquitin ligase (CRL4-Cdt2) demonstrate that this pathway plays a significant role in promoting cell cycle progression, specifically promoting G2 progression. This study investigate the effect of failure to degrade Set8 in S-phase of the cell cycle via CRL4-Cdt2 on gene expression. We used microarrays to detail the effect of the expression of stable form of Set8b H4K20 mono-methyl transferase (Set8b_deltaPIP2) on gene expression Human osteosarcoma-derived human cells were transduced with retroviruses encoding either wt-Set8b or a mutant of Setb8 which is resistant to degradation via CRL4-Cdt2 ubiquitin ligase complex (Set8b_deltaPIP2) or with an a control pMSCV empty virus. 5 days after transduction, cells were harvested and the RNA was extracted by Trizol (Invitrogen) and hybridized to the affymetrix chips array.

Project description:Aberrant expression of the homeodomain transcription factor CDX2 occurs in most cases of acute myeloid leukemia (AML) and promotes leukemogenesis, making CDX2, in principle, an attractive therapeutic target. Conversely, CDX2 acts as a tumor suppressor in colonic epithelium. The effectors mediating the leukemogenic activity of CDX2 and the mechanism underlying its context-dependent properties are poorly characterized, and strategies for interfering with CDX2 function in AML remain elusive. We report data implicating repression of the transcription factor KLF4 as important for the oncogenic activity of CDX2, and demonstrate that CDX2 differentially regulates KLF4 in AML versus colon cancer cells through a mechanism that involves tissue-specific patterns of promoter binding and epigenetic modifications. Furthermore, we identified deregulation of the PPARγ signaling pathway as a feature of AML expressing CDX2, and observed that PPARγ agonists derepress KLF4 and are preferentially toxic to CDX2-positive leukemic cells. These data delineate transcriptional programs associated with CDX2 expression in hematopoietic cells; provide insight into the antagonistic duality of CDX2 function in AML versus colon cancer; and suggest reactivation of KLF4 expression, through modulation of PPARγ signaling, as a new therapeutic modality in a large proportion of AML patients. Experiment 1 (Samples 1-6): The transcriptional changes induced by Cdx2 were assessed ex vivo in primary murine hematopoietic stem and progenitor cells. Bone marrow cells were harvested from 3x15 C57BL/6 mice, and differentiated cells were removed by incubation with rat antibodies against lineage antigens (CD3, CD4, CD8, Gr-1, B220, CD19, IL-7R, Ter119) followed by depletion with magnetic beads (Dynabeads, Invitrogen). Lineage-depleted cells were stained with APC-conjugated anti-c-Kit and PE-Cy5-conjugated goat anti-rat antibodies, and c-Kit+ Lin– cells were sorted using a BD FACSAria cell sorter (BD Biosciences). Cells were plated in RetroNectin-coated tissue culture dishes (Takara Bio) and transduced twice with pMSCV-Cdx2-IRES-GFP or pMSCV-IRES-GFP retroviral constructs. After 48 hours, GFP-positive cells were sorted using a BD FACSAria cell sorter. Experiment 2 (Samples 7-10): The transcriptional changes induced by Cdx2 were assessed in vivo in Cdx2-initiated murine leukemias and compared with those of leukemias initiated by 5 different MLL fusion oncogenes (previously published data, available at GSE13690). Bone marrow cells isolated from C57BL/6 mice were transduced with pMSCV-Cdx2-IRES-GFP, and 8x10e5 GFP-positive cells were injected into lethally irradiated syngeneic recipient mice after 48 hours, followed by injection of 1x10e6 spleen cells from primary leukemic animals into sublethally irradiated secondary recipients. Spleen cells from secondary leukemic animals were harvested.

Project description:PPARM-NM-3 is a master transcriptional regulator of adipogenesis. Hence, the identification of PPARM-NM-3 coactivators should help reveal mechanisms controlling gene expression in adipose tissue development and physiology. We show that the non-coding RNA Steroid receptor RNA Activator, SRA, associates with PPARM-NM-3 and coactivates PPARM-NM-3-dependent reporter gene expression. Overexpression of SRA in ST2 adipocyte precursor cells promotes their differentiation into adipocytes. Conversely, knockdown of endogenous SRA inhibits 3T3-L1 preadipocyte differentiation. Microarray analysis reveals hundreds of SRA-responsive genes in adipocytes, including genes in cell cycle, insulin and TNFM-NM-1 signaling pathways. Some functions of SRA may involve mechanisms other than coactivation of PPARM-NM-3. SRA increases insulin-stimulated glucose uptake in adipocytes. SRA promotes S-phase entry during mitotic clonal expansion, decreases expression of cyclin-dependent kinase inhibiters p21Cip1 and p27Kip1, and increases phosphorylation of Cdk1/Cdc2. SRA also inhibits the TNFM-NM-1-induced phosphorylation of c-Jun NH2-terminal kinase. In conclusion, SRA enhances adipogenesis and adipocyte function through multiple pathways. Total RNA was isolated from fully differentiated (MDIT day 4) SRA overexpressing (pMSCV-SRA) and control (pMSCV empty vector) ST2 adipocytes, or fully differentiated (MDIT day 8) shSRA knockdown (pSuperior-shSRA) or shControl (pSuperior-shcontrol) 3T3-L1 adipocytes. Genome wide gene expression analysis was performed using Affymetrix mouse genome 430 2.0 arrays. Triplicate samples were analyzed.

Project description:The effect of CD151 expression onto the kinome of Jurkat T cells was assessed using kinome analysis. CD151 was expressed in Jurkat T cells by retroviral transduction based on a pMSCV vector. Entrez Gene: 977 UniProtKB: P48509 Jurkat T cells were transduced with the MSCV-CD151 vector and successfully transduced cells were selected using puromycin. For the kinome array experiments 3 independent samples of Jurkat cells and three independent samples of J-CD151 cells were collected. To minimize unspecific background signals, lysates from Jurkat and J-CD151 T cells harvested at different growth stages, which were then pooled to provide one sample prior to loading on the Kinexus antibody microarrays.
