Expression data from vehicle or PD-0332991 treated human T-ALL lines

ABSTRACT: Cyclin D3 is critical hematopoiesis and loss of cyclin D3 leads to resistance to transformation of bone marrow progenitors by Notch1-IC. We used a small molecule targeting cyclin D3:CDK4/6 activity to study whether its inhibition is an effective therapeutic strategy. We analyzed T-ALL lines in vitro with PD-0332991 or vehicle control to determine genes affected by the drug. CEM, Jurkat, DND41, and CUTL-1 cell lines were treated with 1 uM PD-0332991 or DMSO for 15 hours prior to RNA extraction and hybridization to Human Genome U133 Plus 2.0 Affymetrix arrays.

D-type cyclins form complexes with cyclin-dependent kinases (CDK4/6) and promote cell cycle progression. Although cyclin D functions appear largely tissue specific, we demonstrate that cyclin D3 has unique functions in lymphocyte development and cannot be replaced by cyclin D2, which is also expressed during blood differentiation. We show that only combined deletion of p27(Kip1) and retinoblastoma tumor suppressor (Rb) is sufficient to rescue the development of Ccnd3(-/-) thymocytes. Furthermore ...[more]

Gene expression profile of mouse breast cancer V720 cells treated with vehicle or PD 0332991

Project description:D-cyclins represent components of cell cycle machinery. To test the efficacy of targeting D-cyclins in cancer treatment, we engineered mouse strains which allow acute and global ablation of individual D-cyclins in a living animal. Ubiquitous shutdown of cyclin D1 or inhibition of cyclin D associated kinase activity in mice bearing ErbB2-driven mammary carcinomas halted cancer progression and triggered tumor-specific senescence, without compromising the animals' health. Ablation of cyclin D3 in mice bearing T-cell acute lymphoblastic leukemias (T-ALL) triggered tumorspecific apoptosis. Such selective killing of leukemic cells can be also achieved by inhibiting cyclin D associated kinase activity in mouse and human T-ALL models. Hence, contrary to what one might expect from ablation of a cell cycle protein, acute shutdown of a D-cyclin leads not only to cell cycle arrest, but it also triggers tumor cell senescence or apoptosis, and it affects different tumor types through distinct cellular mechanisms. Inhibiting cyclin D-activity represents a highly-selective anticancer strategy which specifically targets cancer cells without significantly affecting normal tissues. Mouse breast cancer V720 cells were cultured in the presence of the CDK4/6 inhibitor PD 0332991 (PD; 1 microM) or vehicle (VO) for 24 hrs. Experiment was done in biological triplicate. A total of 6 RNA samples (3 vehicle treated and 3 PD 0332991 treated samples) were used for microarray expression analysis.

Expression data from E13.5 Fetal Liver LSK Hes1-GFP positive and E13.5 Fetal Liver LSK Hes1-GFP negative

Project description:Notch signaling defines a conserved, fundamental pathway, responsible for determination in metazoan development and is widely recognized as an essential component of lineage specific differentiation and stem cell self-renewal in many tissues including the hematopoietic system. Until recently, the majority of studies in the hematopoietic system focused on Notch signaling in lymphocyte differentiation and knowledge of individual Notch receptor roles in early hematopoiesis has been limited due to a paucity of genetic tools available To fate-map Notch receptor expression and pathway activity in the hematopoietic system we used tamoxifen-inducible CreER knock-in mice for individual Notch receptors in combination to a novel Notch reporter strain (Hes1GFP) and a conditional gain of function allele of Notch2 receptor (Rosa-lsl-ICN2). E13.5 Foetal Liver lineage negative, cKit+, Sca1+ cells were sorted from Hes-GFP mice for RNA extraction and hybridization on Affymetrix microarrays

Expression data from c-Myc+ Notch1 T-ALL initiating cells

Project description:Missense FBXW7 mutations are prevalent in various tumors, including T-cell acute lymphoblastic leukemia (T-ALL). To study the effects of such lesions, we generated animals carrying regulatable Fbxw7 mutant alleles. We show here that these mutations specifically bolster cancer-initiating cell activity in collaboration with Notch1 oncogenes, but spare normal hematopoietic stem cell function. We were also able to show that FBXW7 mutations specifically affect the ubiquitylation and half-life of c-Myc protein, a key T-ALL oncogene. Using animals carrying c-Myc fusion alleles, we connected Fbxw7 function to c-Myc abundance and correlated c-Myc expression to leukemia-initiating activity. Three independent Notch1 T-ALL were derived on c-Myc-GFP background and sorted from the spleen of leukemic mice on the basis of GFP expression for RNA extraction and hybridization on Affymetrix microarrays

Expression data from embryonic stem cells following siRNA transfection of UPS members [self_renewal]

Project description:While transcriptional regulation of stem cell self-renewal and differentiation has been extensively studied, only a small number of studies have addressed the roles for post-translational modifications in these processes. A key mechanism of post-translational modification is ubiquitination by the ubiquitin-proteasome system (UPS). Using UPS-targeted RNAi screens, we identify novel regulators of pluripotency and differentiation. We focus on two of these proteins, the deubiquitinating enzyme, Psmd14, and the E3 ligase, Fbxw7, and characterize their importance in ES cell pluripotency and cellular reprogramming. Embryonic stem cells were reverse transfected with siRNA, 48 hrs post transfection cells were isloated for RNA extraction and hybridization on Affymetrix microarrays
