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.

Project description:RNA-binding proteins are important regulators of RNA biogenesis and function, and recent work shows that chromatin- and RNA-binding proteins can have regulatory roles in transcription. Several approaches have been developed to predict RNA-binding proteins and to identify them experimentally at large scale, including binding to structural elements as G-quadruplexes. Here, we show that the histone lysine demethylase protein KDM5 can bind to RNA through interaction with G-quadruplexes with high affinity despite neither being categorized as an RNA-binding protein nor identified as a G-quadruplex binding protein across numerous experimental large-scale and computational studies. In addition to characterizing the KDM5 G-quadruplex interaction we show that RNA is directly involved in the formation of KDM5-containing protein complexes. Computational predictions and comparison to other ARID domain containing proteins suggest that the ARID domain is directly interacting with both DNA and RNA across several proteins. Our work highlights that non-canonical aspects of RNA-binding proteins are present, and that G-quadruplex RNA-binding could provide a regulatory mechanism for chromatin-binding proteins with impact on transcription through linking protein complexes within the cell.

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.

Project description:Mutations in the lysine demethylase 5 (KDM5) family of transcriptional regulators are associated with intellectual disability, yet little is known regarding their spatiotemporal requirements or neurodevelopmental contributions. Utilizing the mushroom body (MB), a major learning and memory center within the Drosophila brain, we demonstrate that KDM5 is required within ganglion mother cells and immature neurons for proper axogenesis. Moreover, the mechanism by which KDM5 functions in this context is independent of its canonical histone demethylase activity. Using in vivo transcriptional and binding analyses, we identify a network of genes directly regulated by KDM5 that are critical modulators of neurodevelopment. We find that KDM5 directly regulates the expression of prospero, a transcription factor that we demonstrate is essential for MB morphogenesis. Prospero functions downstream of KDM5 and binds to approximately half of KDM5-regulated genes. Together, our data provide evidence for a KDM5-Prospero transcriptional axis that is essential for proper MB development.

Project description:The goal of this study was to generate a Drosophila model of intellectual disability caused by mutations in kdm5. RNA-seq was used to define the transcriptional defects of a mutation in Drosophila that is analogous to a human intellectual disability-associated allele, kdm5[A512p]. These data revealed a total of 1609 dysregulated genes, 778 of which were upregulated and 831 were downregulated. To determine whether these transcriptional defects were due to the loss of KDM5-induced histone demethylation, we also carried out RNA-seq from a enzymatic inactive strain, kdm5[Jmjc*]. These data revealed a striking similarity between the two datasets and suggest that the primary defect of KDM5[A512P] is loss of histone demethylase activity.

Project description:Rationale: Human pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) provide a platform to identify and characterize factors that regulate the maturation of CMs. The transition from an immature fetal to adult CM state entails coordinated regulation of the expression of genes involved in myofibril formation and OXPHOS among others. Lysine demethylase 5 (KDM5) specifically demethylate H3K4me1/2/3 and have emerged as potential regulators of expression of genes involved in cardiac development and mitochondrial function.Objectives: The purpose of this study is to determine the role of KDM5 in iPSC-CM maturation.Methods and Results: KDM5A, B, and C proteins were mainly expressed in the early post-natal stages and their expressions were progressively downregulated in the postnatal cardiomyocytes and were absent in adult hearts and CMs. In contrast, KDM5 proteins were persistently expressed in the iPSC-CMs up to 60 days after the induction of myogenic differentiation, consistent with the immaturity of these cells. Inhibition of KDM5 by KDM5-C70 -a pan-KDM5 inhibitor, induced differential expression of 2,372 genes, including upregulation of genes involved in fatty acid oxidation (FAO), OXPHOS, and myogenesis in the iPSC-CMs. Likewise, genome-wide profiling of H3K4me3 binding sites by the CUT&RUN (Cleavage Under Targets & Release Using Nuclease) assay showed enriched of the H3K4me3 peaks at the promoter regions of genes encoding FAO, OXPHOS, and sarcomere proteins. Consistent with the chromatin and gene expression data, KDM5 inhibition increased expression of multiple sarcomere proteins and enhanced myofibrillar organization. Furthermore, inhibition of KDM5 increased H3K4me3 deposits at the promoter region of the ESRRA gene and increased its RNA and protein levels. Knockdown of ESRRA in KDM5-C70-treated iPSC-CM suppressed expression of a subset of the KDM5 targets. In conjunction with changes in the gene expression, KDM5 inhibition increased oxygen consumption rate and contractility in iPSC-CMs.

Project description:Loss of function mutations in the histone methyltransferase KMT2D are common in lymphomas but difficult to target. We reported targeting KDM5 restores epigenetic balance in germinal centre (GC) lymphomas. Here, we show the KDM5 family are over-expressed in mantle cell lymphoma (MCL). GS716054, a pro-drug, increases H3K4 trimethylation (H3K4me3) and kills MCL cells including TP53 mutated cells via suppression of the MYC pathway. It can overcome ibrutinib resistance and synergises with ibrutinib. These data suggest a possible role for KDM5-inhibitors in advanced MCL.

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. Wild-type yeast or yeast with JHD2 deleted were grown to mid-log phase. ChIP analysis performed for H3K4me3, Pol2, IgG.
