Project description:The lysine demethylase 3A (KDM3A, JMJD1A or JHDM2A) controls transcriptional networks in a variety of biological processes such as spermatogenesis, metabolism, stem cell activity and tumor progression. We matched transcriptomic and ChIP-Seq profiles to decipher a genome-wide regulatory network of epigenetic control by KDM3A in prostate cancer cells. ChIP-Seq experiments monitoring histone 3 lysine 9 (H3K9) methylation marks show global histone demethylation effects of KDM3A. Combined assessment of histone demethylation events and gene expression changes presented major transcriptional activation suggesting that distinct oncogenic regulators may synergize with the epigenetic patterns by KDM3A. Pathway enrichment analysis of cells with KDM3A knockdown prioritized androgen signaling indicating that KDM3A plays a key role in regulating androgen receptor activity. Matched ChIP-Seq and knockdown experiments of KDM3A in combination with ChIP-Seq of the androgen receptor resulted in a gain of H3K9 methylation marks around androgen receptor binding sites of selected transcriptional targets in androgen signaling including positive regulation of KRT19, NKX3-1, KLK3, NDRG1, MAF, CREB3L4, MYC, INPP4B, PTK2B, MAPK1, MAP2K1, IGF1, E2F1, HSP90AA1, HIF1A, and ACSL3. The cancer systems biology analysis of KDM3A-dependent genes identifies an epigenetic and transcriptional network in androgen response, hypoxia, glycolysis, and lipid metabolism. Genome-wide ChIP-Seq data highlights specific gene targets and the ability of KDM3A to control oncogenic pathways in prostate cancer cells.

Project description:The Hypoxia-Inducible Factors induce the expression of the histone demethylases JMJD1A (KDM3A) and JMJD2B (KDM4B), linking the hypoxic tumor microenvironment to epigenetic mechanisms that may foster tumor progression. Using transcript profiling, we have identified genes that are regulated by JMJD1A and JMJD2B in both normoxic and hypoxic conditions in SKOV3ip.1 ovarian cancer cells. This dataset includes expression data obtained from exposing ovarian cancer cells to hypoxia in combination with siRNA-mediated knockdown of the hypoxia-inducible histone demethylases JMJD1A and JMJD2B. These data were used to both identify functional overlap between each histone demethylase, as well as identify effectors of tumor growth mediated by JMJD2B (KDM4B) in normoxia and hypoxia.

Project description:Cilia are dynamic antennae that sense the extracellular environment adjusting their length to maintain homeostasis. Mutant mouse models for the lysine demethylase KDM3A (JMJD1A, JMHD2A) share phenotypic features with human ciliopathies, including obesity and metabolic syndrome. Here we show that cilia of Kdm3a mutants are unstable with dysregulated length ranges accumulating intraflagellar transport proteins (IFTs) at the ciliary tip. RNA sequencing and mass-spectrometry identified actin cytoskeleton as the most miss-regulated feature during the ciliary cycle of KDM3A null cells and revealed that IFT81 contains Nε-methylated lysines in vivo to which recombinant KDM3A binds without subsequent demethylation. Mutations in these IFT81 methyl-lysine residues however stabilize KDM3A null cilia and potentiate ciliogenesis surpassing wild type cells; a synergism phenocopied by wild type cultures through the simultaneous destabilization of the actin cytoskeleton when over-expressing IFT81 lysine-mutants. Our work reveals that ciliogenesis requires the coordinated release of cytoskeletal constrains and the presence of intraflagellar transport proteins which KDM3A integrates aided by post-translationally modifiable lysine residues in IFT81.
