(R)-2-hydroxyglutarate inhibits KDM5 histone lysine demethylases to drive tumorigenesis in IDH-mutant cancers

Project description:Oncogenic mutations in isocitrate dehydrogenase (IDH)-1 and -2 occur in a wide range of cancers, including acute myeloid leukemias (AMLs) and gliomas1-3. Mutant IDH enzymes convert 2-oxoglutarate (2OG) to (R)-2-hydroxyglutarate [(R)-2HG]4,5, an oncometabolite that induces cellular transformation by dysregulating 2OG-dependent enzymes. The only direct target of (R)-2HG known to contribute to transformation is the 5-methylcytosine hydroxylase TET2, and there is ample evidence to suggest that (R)-2HG drives leukemogenesis at least in part by inhibiting TET26,7. However, IDH mutations, but not TET2 mutations, are specifically associated with aggressive hematologic diseases, suggesting that (R)-2HG has targets other than TET2 that contribute to mutant IDH-mediated transformation. Here, we report that (R)-2HG directly inhibits KDM5 histone lysine demethylases in IDH-mutant AMLs and gliomas to induce cellular transformation. These studies provide a functional link between dysregulation of histone lysine methylation and tumorigenesis in IDH-mutant cancers.

KDM5 histone demethylases repress innate immune response via suppression of STING

Project description:Tri-methylation on histone H3 lysine 4 (H3K4me3) is enriched near transcription start sites and correlates with active transcription. Like other histone marks, methylation on H3K4 is catalyzed by the respective methyltransferases and erased by demethylases. Lysine demethylase 5 (KDM5) family of Fe (II) and α-ketoglutarate-dependent dioxygenases removes the methyl groups from H3K4me3. All four family members of KDM5 demethylases (KDM5A-D) share sequence identity, have similar in vitro kinetic parameters, and display functional redundancy. To determine the effects of complete depletion of KDM5 activity, we treated MCF7 cells with DMSO, or two pan-KDM5 specific inhibitors, KDM5-C70 (our lab code 443) and CPI-48 (our lab code 278) and performed RNA sequencing to determine gene expression changes after KDM5 inhibitor treatment.

(R)-2-Hydroxyglutarate Inhibits KDM5 Histone Lysine Demethylases to Drive Transformation in IDH-Mutant Cancers.

Project description:Oncogenic mutations in isocitrate dehydrogenase 1 (IDH1) and IDH2 occur in a wide range of cancers, including acute myeloid leukemia (AML) and glioma. Mutant IDH enzymes convert 2-oxoglutarate (2OG) to (R)-2-hydroxyglutarate [(R)-2HG], an oncometabolite that is hypothesized to promote cellular transformation by dysregulating 2OG-dependent enzymes. The only (R)-2HG target that has been convincingly shown to contribute to transformation by mutant IDH is the myeloid tumor suppressor TET2. However, there is ample evidence to suggest that (R)-2HG has other functionally relevant targets in IDH-mutant cancers. Here, we show that (R)-2HG inhibits KDM5 histone lysine demethylases and that this inhibition contributes to cellular transformation in IDH-mutant AML and IDH-mutant glioma. These studies provide the first evidence of a functional link between dysregulation of histone lysine methylation and transformation in IDH-mutant cancers.SignificanceMutant IDH is known to induce histone hypermethylation. However, it is not known if this hypermethylation is functionally significant or is a bystander effect of (R)-2HG accumulation in IDH-mutant cells. Here, we provide evidence that KDM5 inhibition by (R)-2HG contributes to mutant IDH-mediated transformation in AML and glioma. This article is highlighted in the In This Issue feature, p. 1275.

H3K4me3 ChIP in multiple myeloma MM1S cells in the presence and absence of KDM5-C70

Project description:In this experiment we demonstrate the use of an inhibitor of the KDM5 family of histone demethylases, KDM5-C70, on H3K4me3 marks in the multiple myeloma cell line MM1S. KDM5-C70 increases H3K4me3 in a global fashion across the genome. Examination of H3K4me3 mark across MM1S cells treated with either KDM5-C70 or vehicle control

KDM5 Lysine Demethylases Are Involved in Maintenance of 3'UTR Length [RNA-Seq]

Project description:We discovered that the Saccharomyces cerevisiae lysine demethylase, Jhd2 (also known as KDM5), recruits 3'UTR processing machinery and promotes alteration of 3'UTR length in a demethylase-dependent manner. Interaction of Jhd2 with both chromatin and RNA suggests that Jhd2 affects selection of polyadenylation sites through a transcription-coupled mechanism. For 3'READs analysis, wild-type yeast or yeast with JHD2 deleted were grown to mid-log phase and RNA was extracted as mentioned above. cDNA libraries enriched for 3'UTRs were prepared as previously published and as noted in Figure 4a [28]. Samples were then subjected to RNA sequencing on the Illumina Hiseq 2000 using 50bp single end reads. Data was analyzed as previously [Hoque M] with the following modifications: The adapter sequences were trimmed off the single-ended reads. The remaining reads longer than 15 bp were mapped to yeast genome SacCer3 using bowtie2 [Langmead B 2012] with the setting '-5 4 --local', trimming off 4bp from 5' and allowing soft clipping (S) at both ends. The alignments were then filtered by 1) MAPQ>=10, 2) mismatches <= 5%, 3) unaligned 5' Ts >=2 to get the PASS reads. The last aligned positions of the PASS reads were grouped to pA clusters with a clustering size of 24 bp. Each pA cluster was assigned to one of the genes defined by SGD [Cherry JM]. The 3' end of a gene was extended 1000bp from the end of CDS until it overlaps with another gene in the same direction. The pA Clusters were then filtered by contains 1) >= 3 PASS reads 2) >= 5% of all PASS reads mapped to the gene.

Effect of KDM5 histone demethylase in 3T3-L1 differentiation

Project description:The KDM5 histone demethylases regulate histone methylation to modulate chromatin structure and gene expression. Using a KDM5 enzyme inhibitor (KDM5-C70) and transcriptome profiling by RNA-sequencing in 3T3-L1 cells at different states of differentiation, we determined that KDM5 activity influences the induction of genes associated with cell cycle regulation and mitochondrial function.
