Comparison of fibroblasts from ARH3-mutated patients and controls by transcription profiling.

ABSTRACT: Mutations in the ARH3 (ADPRHL2) hydrolase that catabolises ADP-ribose are associated with neurodegeneration and ataxia. In our experiments we have found that ARH3-defective cells accumulate mono-(ADP-ribose) scars on histones that may prevent other epigenetic modifications from happening at these sites. Transcriptomic analyses thus could be useful to show whether and how persistence of these marks might translate into the pathogenesis. We have employed primary human fibroblasts (cultured in individual cell lines) from two ARH3-mutated patients (A1, A2), harbouring the homozygous mutations Q334 (A1 & A2/siblings) and two unaffected controls (ARH3 ctrl/father & unrelated 1BR) to run RNA-seq.

Cockayne syndrome group B deficiency reduces H3K9me3 chromatin remodeler SETDB1 and exacerbates cellular aging

Project description:Cockayne syndrome (CS) is an accelerated aging disorder, caused by mutations in the CSA or CSB genes. In CSB-deficient cells, poly (ADP ribose) polymerase (PARP) is persistently activated by unrepaired DNA damage and PARP consumes and depletes cellular nicotinamide adenine dinucleotide (NAD), which leads to mitochondrial dysfunction. Here, the distribution of poly (ADP ribose) (PAR) was determined in CSB-deficient cells using ADPr-ChAP (ADP ribose-chromatin affinity purification), and the results show striking enrichment of PAR at transcription start sites (TSS), depletion of heterochromatin, and downregulation of H3K9me3-specific methyltransferases SUV39H1 and SETDB1. Induced-expression of SETDB1 in CSB-deficient cells downregulated PAR and normalized mitochondrial function. The results suggest that defects in CSB are strongly associated with loss of heterochromatin, downregulation of SETDB1, increased PAR in highly-transcribed regions, and mitochondrial dysfunction.

Engineering Af1521 macro domain increases ADP-ribose binding affinity and leads to the identification of more ADP-ribosylated proteins

Project description:Protein ADP-ribosylation is a covalent, reversible post-translational modification that has important functions in several cellular mechanisms. The identification of modified proteins in cells has proven challenging and, due to the low abundance of protein ADP-ribosylation, has mainly been possible via enrichment methodologies using ADP-ribose binding domains. Here, using random mutagenesis and in vitro selection with an ADP-ribosylated histone peptide, we engineered the archaeal Af1521 macro domain to generate an engineered isoform containing nine mutations that displays significantly increased affinity towards ADP-ribose. Comparison of the wild-type and the engineered Af1521 macro domains using our proteomic ADP-ribosylome enrichment workflow demonstrated an increased identification rate of ADP-ribosylated proteins with the engineered Af1521.

Loss of ZBTB24, a novel non-homologous end-joining protein, impairs class-switch recombination in ICF syndrome

Project description:The autosomal recessive immunodeficiency, centromeric instability and facial anomalies (ICF) syndrome is a genetically heterogeneous disorder. Despite recent successes in the identification of the underlying gene defects, it is currently unclear how mutations in any of the four known ICF genes cause a primary immunodeficiency. Here we demonstrate that loss of ZBTB24 in B cells from ICF2 patients impairs non-homologous end-joining (NHEJ) during immunoglobulin class-switch recombination and consequently impairs immunoglobulin production and subtype balance. Mechanistically, we found that ZBTB24 associates with poly(ADP-ribose) polymerase 1 (PARP1) and stimulates auto-poly(ADP-ribosyl)ation of this enzyme. The zinc finger in ZBTB24 binds PARP1-associated poly(ADP-ribose) chains and mediates the PARP1-dependent recruitment of ZBTB24 to DNA breaks. Moreover, by binding to poly(ADP-ribose) chains ZBTB24 protects these moieties from degradation by poly(ADP-ribose) glycohydrolase (PARG). This enhances the poly(ADP-ribose)-dependent interaction between PARP1 and the LIG4/XRCC4 NHEJ complex and promotes NHEJ by facilitating the assembly of this repair complex at DNA breaks. Thus, we uncover ZBTB24 as a regulator of PARP1-dependent NHEJ and class-switch recombination, providing a molecular basis for the immunodeficiency in ICF syndrome.

Expression Analysis Upon PARP-1 or PARG Knockdown in MCF-7 Cells

Project description:Poly(ADP-ribose) polymerase-1 (PARP-1) and poly(ADP-ribose) glycohydrolase (PARG) are enzymes that modify target proteins in the nucleus by the addition and removal, respectively, of ADP-ribose polymers. Although a role for PARP-1 in gene regulation has been well established, the role of PARG is less clear. To investigate how PARP-1 and PARG coordinately regulate global patterns of gene expression, we used short hairpin RNAs (shRNAs) to stably knockdown PARP-1 or PARG in MCF-7 cells, followed by expression microarray analyses.

Global gene expression profile and splicing events of iPS-derived motorneurons from SMA patient, unaffected father and TGC-treated cells

Project description:Spinal Muscular Atrophy (SMA) is an autosomal recessive motor neuron disease and is the second most common genetic disorder leading to death in childhood. Motoneurons derived from induced pluripotent stem cells (iPSC) obtained by reprogramming SMA patient and his healthy father fibroblasts, and genetically corrected SMA-iPSC obtained converting SMN2 into SMN1 with target gene correction (TGC), were used to study gene expression and splicing events linked to pathogenetic mechanisms. Microarray technology was used to assess the global gene expression profile as well as splicing events of iPS-derived motorneurons from SMA patient, unaffected father and TGC-treated cells. The microarray data derived from three different groups: SMA patient, healty father and treated SMA patient's cells. Each population consists of three RNA profiling cell samples.

Cellular ADP-ribosylome characterization with HCD and EThcD

Project description:Protein ADP-ribosylation is a post-translational modification involved in important physiological and pathological processes. Here, we present an optimized method using the Orbitrap Fusion Tribrid mass spectrometer, which drastically improves the overall ADP-ribosylation site localization score and boosts the identification of ADP-ribosylated peptides. We compared the HCD, ETcaD or EThcD fragmentation methods for the identification of ADP-ribose acceptor sites in a complex cellular sample and further combined them in a product dependent manner, exploiting the unique fragmentation properties of the ADP-ribose moiety as a trigger for a targeted fragmentation of modified peptides.

A function for the hnRNP A1/A2 proteins in transcription elongation

Project description:The hnRNP A1 and A2 proteins regulate processes such as alternative pre-mRNA splicing and mRNA stability. Here, we report that a reduction in the levels of hnRNP A1 and A2 by RNA interference or their cytoplasmic retention by osmotic stress drastically increases the transcription of a reporter gene. Based on previous work, we propose that this effect may be linked to a decrease in the activity of the transcription elongation factor P-TEFb. Consistent with this hypothesis, the transcription of the reporter gene was stimulated when the catalytic component of P-TEFb, CDK9, was inhibited with DRB. While low levels of A1/A2 stimulated the association of RNA polymerase II with the reporter gene, they also increased the association of CDK9 with the repressor 7SK RNA, and compromised the recovery of promoter-distal transcription on the Kitlg gene after the release of pausing. Transcriptome analysis revealed that more than 50% of the genes whose expression was affected by the siRNA-mediated depletion of A1/A2 were also affected by DRB. RNA polymerase II-chromatin immunoprecipitation assays on DRB-treated and A1/A2-depleted cells identified a common set of repressed genes displaying increased occupancy of polymerases at promoter-proximal locations, consistent with pausing. Overall, our results suggest that lowering the levels of hnRNP A1/A2 elicits defective transcription elongation on a fraction of P-TEFb-dependent genes, hence favoring the transcription of P-TEFb-independent genes.

Cyp27c1 red-shifts the spectral sensitivity of photoreceptors by converting vitamin A1 into A2

Project description:The goal of this project was to identify the dehydrogenase enzyme that converts vitamin A1 into A2, resulting in red-shifted spectral sensitivity of the visual system. We conducted next-generation sequencing of mRNA derived from the retinal pigment epithelium (RPE) of two animal models that use vitamin A2 as a chromophore to identify this enzyme. Zebrafish switch from vitamin A1 to A2 when treated with thyroid hormone, so we profiled the RPE from TH- and vehicle-treated zebrafish (n=3). The adult American bullfrog sequesters vitamin A2 within the dorsal part of the retina, but lacks vitamin A2 in the ventral retina. We therefore also profiled dorsal and ventral American bullfrog RPE (n=3). Using this approach, we identified cytochrome p450 family member cyp27c1 as strongly enriched in both datasets, and determined through additional experiments that cyp27c1 is both necessary and sufficient for vitamin A2 production.
