Project description:To understand the role of the H3K27me3 demethylases, UTX and JMJD3, in B cell differentiation. CUT&Tag for H3K27me3 was performed on CreCtrl and dKO (UTX and JMJD3-deficient) PC at day three post in vivo stimulation with LPS.

Impact of Jmjd3 and Utx histone demethylases on Histone H3 lysine 27 trimethylation (H3K27Me3) in mature CD4 SP thymocytes

Project description:While histone H3 lysine 27 trimethylation (H3K27Me3) is associated with gene silencing, whether H3K27Me3 demethylation affects transcription and cell differentiation in vivo has remained elusive. To investigate this, we conditionally inactivated the two H3K27Me3 demethylases, Jmjd3 and Utx, in non-dividing intrathymic CD4+ T cell precursors. We show that both enzymes redundantly promote H3K27Me3 removal at, and expression of, a specific subset of genes involved in terminal thymocyte differentiation, especially S1pr1, encoding a sphingosine-phosphate receptor required for thymocyte egress. Floxed alleles of the genes encoding Utx and Jmjd3 (Kdm6a and Kdm6b, respectively) were deleted in double positive (DP) thymocytes carrying a CD4 Cre transgene. Genome-wide H3K27Me3 ChipSeq was performed on (i) pre-selection (CD69lo) DP thymocytes from wild-type mice carrying an endogenous polyclonal TCR repertoire, (ii) mature (TCRhi CD24lo) CD4 SP thymocytes from wild type (Wt), Jmjd3KO, UtxKO and dKO mice carrying an endogenous polyclonal TCR repertoire and (iii) mature (Va2hi CD24lo) CD4 SP thymocytes from wild type and dKO mice carrying the OTII TCR transgene.

Gene expression profiling in mature OT-II TCR transgenic CD4 SP thymocytes, either Jmjd3- and Utx-deficient or -sufficient.

Project description:The biological functions of histone demethylases Jmjd3 and Utx remain poorly understood. We assessed such functions in developing T cells, using conditional (CD4-Cre-mediated) gene disruption, by inactivating Kdm6a and Kdm6b, respectively encoding Utx and Jmjd3, in immature CD4+CD8+ thymocytes. We compared microarray gene expression in mature (Va2hi CD24lo) mutant and wild-type CD4+CD8- thymocytes carrying the OT-II TCR transgene. We show that Jmjd3 and Utx redundantly promote H3K27Me3 removal at, and expression of, a specific subset of genes involved in terminal thymocyte differentiation, especially S1pr1, encoding a sphingosine-phosphate receptor required for thymocyte egress. Mature (Va2hi CD24lo) CD4 thymocytes were sorted from freshly prepared single-cell suspensions OT-II TCR transgenic thymocytes deficient for Utx and Jmjd3 (dKO, CD4-Cre conditional deletion of floxed Kdm6a and Kdm6b alleles), and from Cre-negative controls (wild-type). Total RNA was extracted from sorted thymocytes using the RNeasy Plus Mini Kit (Qiagen) and processed for microarray analyses (Affymetrix Mouse Exon 1.0 ST array) at the NCI microarray facility, following the manufacturer’s recommendation. Data is generated from 3 replicates from each experiment.

Characterizing the contrasting roles of JMJD3 and UTX histone demethylases in T cell acute lymphoblastic leukemia [JMJD3_CUTLL1_ChIP-seq]

Project description:T-cell acute lymphoblastic leukemia (T-ALL) is an immature hematopoietic malignancy driven mainly by oncogenic activation of NOTCH1 signaling. In this study we assayed for genome-wide localization of JMJD3 enrichment. This piece of data was further integrated to expression changes using RNA sequencing as well as ChIP-Sequencing analysis of H3K27me3 upon genomic/genetic knock-down or chemical inhibition of JMJD3 and UTX. These results, coupled to genomic analysis of primary samples for the genomic status of the UTX gene in T-ALL, helped us to identify a hitherto unknown role of JMJD3 as an oncogenice facilitator in leukemia whereas UTX plays a tumor suppressor role. JMJD3 ChIP: 10 million cells were used for the ChIP and precipitated using 10micrograms of antibody (abgent, AP1022a) against human JMJD3.

Characterizing the contrasting roles of JMJD3 and UTX histone demethylases in T cell acute lymphoblastic leukemia [GSKJ4_ChIP-seq]

Project description:T-cell acute lymphoblastic leukemia (T-ALL) is an immature hematopoietic malignancy driven mainly by oncogenic activation of NOTCH1 signaling. In this study we chemically inhibited the H3K27me3 demethylase JMJD3 using the GSKJ4 inhibitor and assayed for genome-wide changes in H3K27me3 and JMJD3 enrichment. This piece of data was further integrated to expression changes using RNA sequencing as well as ChIP-Sequencing analysis of H3K27me3 upon genomic knock-down of JMJD3 and UTX. These results, coupled to genomic analysis of primary samples for the genomic status of the UTX gene in T-ALL, helped us to identify a hitherto unknown role of JMJD3 as an oncogenice facilitator in leukemia whereas UTX seems to play a tumor suppressor role. Histone ChIP: Half to one million cells were treated with micrococcal nuclease (MNASE) to generate mononucleosomal particles and an adaptation of the Upstate ChIP protocol was used.

Characterizing the contrasting roles of JMJD3 and UTX histone demethylases in T cell acute lymphoblastic leukemia [short_hairpins_RNA-seq]

Project description:T-cell acute lymphoblastic leukemia (T-ALL) is an immature hematopoietic malignancy driven mainly by oncogenic activation of NOTCH1 signaling. In this study we abrogated the expression of JMJD3 (KDM6B) and UTX (KDM6A) H3K27me3 demethylases in human T-ALL lines and assayed for genome-wide expression changes using RNA sequencing. This piece of data was further integrated to ChIP-Sequencing analysis of H3K27me3 from the same treatment as well as H3K27me3 and JMJD3 genome-wide analysis from treatment of T-ALL lines with the GSKJ4 inhibitor. These results, coupled to genomic analysis of primary samples for the genomic status of the UTX gene in T-ALL, helped us to identify a hitherto unknown role of JMJD3as an oncogenice facilitator in leukemia whereas UTX seems to play a tumor suppressor role. Whole RNA was extracted from 1-5 million T-ALL (lines) cells or primary cells using the RNAeasy kit (Qiagen) according to the manufacturer’s protocol. Poly-A+ (magnetic oligodT-containing beads (Invitrogen)) or Ribominus RNA was used for library preparation. cDNA preparation and strand-specific library construction was performed using the dUTP method. Libraries were sequenced on the Illumina HiSeq 2000 using 50bp single-read method. Differential gene expression analysis was performed for each matched knockdown vs control pairs, separately in each biological or technical replicate in each of two cell lines (CUTLL1, CEM). Three types of comparisons were tested: (a) JMJD3 knockdown vs Renilla, (b) JMJD3 knockdown vs UTX knockdown, and (c) UTX knockdown vs Renilla. Analysis was performed using both DEGseq and Cufflinks packages leading to very similar conclusions.
