Project description:Glis2 is a member of the Gli-similar (Glis) subfamily of Kruppel-like zinc finger transcription factors. To obtain insights into the physiological functions of Glis2, mice deficient in Glis2 expression were generated. These mutant mice develop progressive renal disease associated with fibrosis and inflammation. Gene expression profiles were examined to identify changes in gene expression at early stages of progressive renal disease in Glis2 mutant mice. Experiment Overall Design: To analyze changes in gene expression, microarray analysis was performed using RNA from kidneys of PND25 and PND60 wild type and Glis2-mutant mice. Experiment Overall Design: Gene expression profiles were compared between kidneys of PND25 wt and Glis2 mutant mice and between PND60 wt and Glis2 mutants. RNA from three kidneys were pooled. RNA from two independent experiments was used and each microarray analysis was performed in duplicate.

Project description:Transcriptome Sequence Analysis of Pediatric Acute Megakaryoblastic Leukemia Identifies An Inv(16)(p13.3;q24.3)-Encoded CBFA2T3-GLIS2 Fusion Protein As a Recurrent Lesion in 39% of Non-Infant Cases: A Report From the St. Jude Children’s Research Hospital – Washington University Pediatric Cancer Genome Project. Acute Megakaryoblastic Leukemia (AMKL) accounts for ~10% of childhood acute myeloid leukemia (AML). Although AMKL patients with down syndrome (DS-AMKL) have an excellent 5 year event-free survival (EFS), non-DS-AMKL patients have an extremely poor outcome with a 3 year EFS of less than 40%. With the exception of the t(1;22) translocation seen in infant non-DS-AMKL, little is known about the molecular genetic lesions that underlie this leukemia subtype. To define the landscape of mutations that occur in non-DS-AMKL, we performed transcriptome sequencing on diagnostic blasts from 14 cases (discovery cohort) using the illumina platform. Our results identified chromosomal rearrangements resulting in the expression of novel fusion transcripts in 12/14 cases. Remarkably, in 7/14 cases we detected an inversion on chromosome 16 [inv(16)(p13.3;q24.3)] that resulted in the juxtaposition of the CBFA2T3, a member of the ETO family of transcription factors, next to GLIS2 resulting in a CBFA2T3-GLIS2 chimeric gene encoding an in frame fusion protein. 6 cases in the discovery cohort fused exon 10 of CBFA2T3 to exon 3 of GLIS2, while 1 case carried a larger product that fused exon 11 of CBFA2T3 to exon 1 of GLIS2. Both products retain the 3 CBFA2T3 N-terminal nervy homology regions that mediate protein interactions, and the 5 GLIS2 C-terminal zinc finger domains that bind the Glis DNA consensus sequence, along with one of its N-terminal transcriptional regulatory domains. GLIS2 is a member of the GLI super family of transcription factors and has been demonstrated to play a role in regulating expression of GLI target genes as well as inhibiting WNT signaling through the binding of beta catenin. Although GLIS2 is not normally expressed in hematopoietic cells, the translocation results in high level expression of the CBFA2T3-GLIS2 fusion protein. In addition to CBFA2T3-GLIS2, chimeric transcripts were detected in 6/7 cases that lacked evidence of the inv(16)(p13.3;q24.3). Specifically, we detected GATA2-HOXA9, MN1-FLI1, NIPBL-HOXB9, NUP98-KDM5A, GRB10-SDK1 and C8orf76-HOXA11AS, each in an individual case. Importantly, several of the genes involved in these translocations either play a direct role in normal megakaryocytic differentiation (GATA2 and FLI1), or have been previously shown to be involved in leukemogenesis (HOXA9, MN1, HOXB9). Evaluation of a recurrency cohort of 42 samples including 14 additional pediatric cases and 28 adult cases by RT-PCR revealed 4 additional pediatric samples carrying CBFA2T3-GLIS2 for an overall frequency of 39% in pediatric AMKL. In addition to these somatic structural variations, we also identified mutations in genes previously shown to play a role in megakaryoblastic leukemia including activating mutations in JAK2 and MPL (36%). To gain insight into the mechanism whereby CBFA2T3-GLIS2 promotes leukemogenesis, we introduced the fusion into murine hematopoietic cells and assessed its effect on in vitro colony replating as a surrogate measure of self-renewal. Hematopoietic cells transduced with a mCherry expressing retroviral vector failed to form colonies after the second replating. By contrast, expression of either wild-type GLIS2 or the CBFA2T3-GLIS2 fusion resulted in a marked increase in the self-renewal capacity, with colony formation persisting through eight replatings. Immunophenotypic analysis of the CBFA2T3-GLIS2 expressing colonies revealed evidence of megakaryocytic differentiation. Importantly, the CBFA2T3-GLIS2 cells remained growth factor dependent suggesting that cooperating mutations in growth factor signaling pathways are required for full leukemic transformation. Taken together these data identify a novel cryptic inv(16)-encoded CBFA2T3-GLIS2 fusion protein as a recurrent driver mutation in approximately 40% of non-infant pediatric non-DS-AMKLs. Moreover, the majority of pediatric cases that lacked this lesion were shown by transcriptome sequence analysis to contain other chromosomal rearrangements that encoded fusion proteins that directly alter megakaryocytic differentiation and/or myeloid cell growth. The alteration of a key transcriptional regulator within the hedgehog signaling pathways in a substantial percentage of pediatric AMKL raises the possibility that inhibition of this pathway may have a therapeutic benefit in this aggressive form of AML. Gene expression profiling was performed on 14 single diagnosis tumor samples

Project description:Eradication of chemotherapy-resistant leukemia stem cells is expected to improve treatment outcomes in patients with acute myelogenous leukemia (AML). In a mouse model of AML expressing the MOZ-TIF2 fusion, we found that Ring1A and Ring1B, components of Polycomb repressive complex 1, play crucial roles in maintaining AML stem cells. Deletion of Ring1A and Ring1B (Ring1A/B) from MOZ-TIF2 AML cells diminished self-renewal capacity and induced the expression of numerous genes including Gli-similar 2 (Glis2). Overexpression of Glis2 caused MOZ-TIF2 AML cells to differentiate into mature cells, whereas Glis2 knockdown in Ring1A/B-deficient MOZ-TIF2 cells inhibited differentiation. Thus, Ring1A/B regulates and maintains AML stem cells in part by repressing Glis2 expression, which promotes their differentiation. These findings provide new insights into the mechanism of AML stem cell homeostasis and reveal novel targets for cancer stem cell therapy.

Project description:Acute megakaryoblastic leukemia (AMKL) is a subtype of leukemia primarily diagnosed in childhood and generally associated with poor prognosis. Genetic alterations found in de novo childhood AMKL include the OTT-MAL fusion, MLL and NUP98 fusions and the recently identified ETO2-GLIS2 fusion that involves two transcriptional regulators. In order to identify ETO2-GLIS2 target genes, we performed two approaches: 1-Ectopic expression of ETO2-GLIS2, ETO2, GLIS2 and OTT-MAL in HEL cells, which does not endogenously express AMKL fusion oncogenes. Transduced cells marked by expression of the GFP were sorted by flow cytometry 24 hours after transduction and RNA was extracted with the Qiagen Rneasy kit including DNase treatment. 2-Expression of a small peptide (NC128), which interferes with the dimerization and cofactor recruitment by the ETO2-GLIS2 fusion, within MO7E cells derived from an AMKL patient and expressing endogenously the ETO2-GLIS2 fusion. Transduced cells marked by expression of the GFP were sorted by flow cytometry 7 days after transduction and RNA was extracted with the Qiagen Rneasy kit including DNase treatment. After quantification of biological replicates, and quality control (Bioanalyser, Agilent), RNA were hybridized on Agilent arrays as indicated below.

Genetic alterations found in de novo childhood AMKL include the OTT-MAL fusion, MLL and NUP98 fusions and the recently identified ETO2-GLIS2 fusion that involves two transcriptional regulators. In order to identify ETO2-GLIS2-bound regions as well as the chromatin landscape in human AMKL cells, we performed ChIP-seq analyses in AMKL MO7E cell line and in AMKL patient derived cells. Since existing GLIS2 antibodies could not successfully pull-down ETO2-GLIS2, we introduced the GFP at the endogenous GLIS2 loci in the MO7E cell line using a CRISPR/Cas9 approach to obtain physiological expression of a GFP-tagged ETO2-GLIS2 (MO7e-KI cell line). ChIP-seq were performed using antibody against GFP and ETO2 to identify ETO2-GLIS2-bound regions, against ERG to investigate colocalization and against chromatin marks to highlight repressed (H3K27me3) and active (H3K4me3: promoters; H3K27Ac, H3K4me1: enhancers) regions.

Project description:Excessive renal fibrosis is a common pathology in progressive chronic kidney diseases. Inflammatory injury and aberrant repair processes contribute to the development of kidney fibrosis. Myeloid cells, particularly monocytes/macrophages, play a crucial role in kidney fibrosis by releasing their proinflammatory cytokines and extracellular matrix components such as collagen and fibronectin into the microenvironment of the injured kidney. Numerous signaling pathways have been identified in relation to these activities. However, the involvement of metabolic pathways in myeloid cell functions during the development of renal fibrosis remains understudied. In our study, we initially reanalyzed single-cell RNA sequencing data of renal myeloid cells from Dr. Denby’s group and observed an increased glycolytic pathway in myeloid cells that are critical for renal inflammation and fibrosis. To investigate the role of myeloid glycolysis in renal fibrosis, we utilized a model of unilateral ureteral obstruction in mice deficient of Pfkfb3, an activator of glycolysis, in myeloid cells (Pfkfb3ΔMϕ) and their wild type littermates (Pfkfb3WT). We observed a significant reduction in fibrosis in the obstructive kidneys of Pfkfb3ΔMϕ mice compared to Pfkfb3WT mice. This was accompanied by a substantial decrease in myeloid cell infiltration, as well as a decrease in the numbers of M1 and M2 macrophages and suppression of macrophage to obtain myofibroblast phenotype in the obstructive kidneys of Pfkfb3ΔMϕ mice. Mechanistic studies indicate that glycolytic metabolites stabilize HIF1α, leading to alterations in macrophage phenotypes that contribute to renal fibrosis. In conclusion, our study implicates that targeting myeloid glycolysis represents a novel approach to inhibit renal fibrosis.

Project description:These data were generated to investigate the impact on the gene expression of the chimeric transcription factor CBFA2T3-GLIS2 (a.k.a ETO2-GLIS2 and abbreviated here as EG) which is associated with pediatric leukemia (LAM7), to assess the functional roles of several domains of this protein (the ETO2 and GLIS2 moiety) on the gene dysregulation induced by EG through the generation of several mutants (deleted for the NHR2 domain of ETO2: dNHR2 or with a C265G mutation in the GLIS2 moiety: C265G). The different EG forms were cloned into a doxycycline-inducible lentiviral vector and transcriptomes were performed 24 hours post doxycycline induction.
