(Submitter supplied) 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. more...

(Submitter supplied) Cockayne syndrome (CS) is a rare premature aging disease, which in the majority of cases is caused by mutations of the genes encoding the CSA or CSB proteins. CS patients display cachectic dwarfism and severe neurological manifestations and die by 12 years of age on average. The CS proteins are involved in transcription and DNA repair, including a specialized form of DNA repair called transcription-coupled nucleotide excision repair (TC-NER). more...

(Submitter supplied) The rare genetic disease Cockayne syndrome (CS) results in mutations in CSA and CSB. Upon UV irradiation, RNA synthesis was arrested: RNA-seq showed 70% of down-regulated genes in common between CSA and CSB deficient cells. ATF3, the product of an immediate early gene was overexpressed and bound to its CRE/ATF site to inhibit its responsive genes. ChIP experiments showed that CSA/CUL4A/DDB1 together with CSB and MDM2, target ATF3. more...

(Submitter supplied) Cockayne Syndrome (CS) is a rare neurodegenerative disease characterized by short stature, cachexia, sun-sensitivity, accelerated aging, and short lifespan. Mutations in two human genes, ERCC8/CSA and ERCC6/CSB, are causative for CS and the protein products of these genes, CSA and CSB, while structurally unrelated, play roles in DNA repair and other aspects of DNA metabolism in human cells. Many clinical and molecular features of CS remain poorly understood, and it has been suggested that CSA and CSB regulate transcription of rDNA genes and ribosome biogenesis. more...

(Submitter supplied) Cockayne syndrome (CS) is a rare genetic neurodevelopmental disorder, characterized by a deficiency in the transcription-coupled nucleotide excision repair pathway. Mutation of Cockayne syndrome B (CSB) affects basal transcription which is considered a major cause of CS neurological dysfunction. Here, we generated a rat model by mimicking a nonsense mutation in the CSB(ERCC6) gene of CS-B patients. CSB-deficient rats exhibit the well-known CS repair characteristics: inability to resume RNA synthesis from stalled RNA polymerase II (RNAP II) and persistent gamma H2AX overexpression after UV damage. In contrast to that of the Csb-/- mouse models, the cerebella of the CSB-deficient rats are more profoundly affected. Both the molecular and the granular layers of the cerebellum cortex showed significant atrophy. The white matter of the cerebellum demonstrated high GFAP staining indicative of reactive astrogliosis. RNA-seq analysis of CSB-deficient rat cerebella revealed that even in the absence of UV damage, CSB affects the expression of hundreds of genes, many of which are neuronal genes, suggesting that transcription dysregulation could contribute to the neurological features in CSB rat models.

(Submitter supplied) Mutations in the Cockayne Syndrome group B (CSB) gene cause severe neurodevelopmental defects and premature aging. As a member of the SWI/SNF family of chromatin remodelers, CSB is best known for its role in transcription-coupled nucleotide excision (TC-NER), but this function neither explains the major disease phenotype nor offers any clue about the selective vulnerability in neurons. Pursuing Cockayne Syndrome-associated genome instability, we uncover an intrinsic mechanism by which elongating RNA polymerase II (RNAPII) undergoes transient pausing at internal T-runs where CSB is required to push RNAPII forward. more...

(Submitter supplied) Cockayne syndrome is an inherited premature aging syndrome associated with developmental and neurological disorders. Mutations in the genomic locus encoding CSB are associated with 80% Cockayne syndrome cases. CSB is invovled in relieving UV-induced and oxidative stree. To gain more insights into the fucntion of CSB under these stress, we use ChIP-seq to determine the genomic localization of CSB 1 hour after UV irradiation and menadione treatment.

(Submitter supplied) Fibroblasts can be directly converted into neurons in vitro by depletion of nPTB, the reprogramming process induces neuronal gene expression while inhibits fibroblast gene expression. Human fibroblasts lacking CSB can not be converted into neurons, unless CSB gene was introduced. This study characterizes the CSB-dependent gene expression alterations during reprogramming. Using Nimblegen microarray we identified differentially expressed genes in induced neurons from wild type CSB reconstituted fibroblasts, and we proved that the difference in gene expression after reprogramming was not observed in CS1AN cells.

(Submitter supplied) As the causative gene for cockayne syndrome, CSB has a well-characerized function in transcription-coupled nucleotide excision repair. However, the complex neurological abnormalities that affect CS patients can not be simply explained by the DNA repair defects. CSB is also involved in RNAP II transcription regulation. This study characterizes the gene expression signatures affected by CSB protein. Using Nimblegen microarray we identified differentially expressed genes in human fibroblasts derived from CS patients as compared to CSB reconstituted cell lines (wild type).
