MetabolomicsNAD+ augmentation restores mitophagy and limits accelerated aging in Werner syndrome (Extracellular UPLC-MS assay)

Metabolic dysfunction is a primary feature of Werner syndrome (WS), a human premature aging disease caused by mutations in the gene encoding the Werner (WRN) DNA helicase. WS patients exhibit severe metabolic phenotypes, but the underlying mechanisms are not understood, and whether the metabolic ...

TranscriptomicsGenome-wide DNA methylation profiling of Progeria and Werner syndrome patients
DNA methylation gradiently changes with age and is likely to be involved in aging-related processes resulting in phenotype changes and increased susceptibility to certain diseases. The Hutchinson-Gilford Progeria Syndrome (HGP) and Werner Syndrome are two premature aging diseases showing features of...

GenomicNext Generation Mendelian Genetics: Atypical Werner Syndrome

Werner syndrome (WS) is an adult-onset progeroid syndrome characterized by accelerated aging. The International Registry of Werner Syndrome in the Department of Pathology, University of Washington, collects WS cases from all over the world. Classical WS is caused by WRN mutations. Those who do no...

TranscriptomicsRNA at 92 M-BM-0C: the non-coding transcriptome of the hyperthermophilic archaeon Pyrococcus abyssi.
The non-coding transcriptome of the hyperthermophilic archaeon Pyrococcus abyssi is investigated using the RNA-seq technology. A dedicated computational pipeline analyzes RNA-seq reads and prior genome annotation to identify small RNAs, untranslated regions of mRNAs, and cis-encoded antisense transc...

TranscriptomicsThe Fun30 ATP-dependent nucleosome remodeler promotes resection of DNA double-strand break ends
Chromosomal double-strand breaks (DSBs) are resected by 5M-bM-^@M-^Y-nucleases to form 3M-bM-^@M-^Y single-strand DNA (ssDNA) substrates for binding by homologous recombination and DNA damage checkpoint proteins. Two redundant pathways of extensive resection were described both in cells and in vitro...

TranscriptomicsAltered gene expression in Werner & Bloom syndromes is associated with sequences having G-quadruplex forming potential
The human Werner and Bloom syndromes (WS and BS) are caused by deficiencies in the WRN and BLM RecQ helicases, respectively. WRN, BLM and their S. cerevisiae homologue Sgs1, are particularly active in vitro in unwinding G-quadruplex DNA (G4-DNA), a family of non-canonical nucleic acid structures fo...

MetabolomicsImproving the Screening Analysis of Pesticide Metabolites in Human Biomonitoring by Combining High-Throughput In Vitro Incubation and Automated LC-HRMS Data Processing
There is a current need to monitor human exposure to a large number of pesticides and other chemicals of emerging concern (CECs). This requires screening analysis with high confidence for these compounds and their metabolites in complex matrices, which is hampered by the fact that no reference stand...

TranscriptomicsTranscription profiling of S. cerevisiae sgs1 mutant and wild type strains grown under DNA damaging and control conditions
Wild type and sgs1 null yeast were grown under DNA damaging (with MMS) conditions or without treatment to log phase and their transcriptional profiles compared. The human aging diseases Werner and Bloom syndromes are a result of mutation of the WRN and BLM genes, respectively. The SGS1 gene of Sacch...

TranscriptomicsGene expression of M. acetivorans producing ANME-1 Mcr during growth on methane vs. growth on methanol
Our goal is to convert methane efficiently into liquid fuels that may be more readily transported. Since aerobic oxidation of methane is less efficient, we focused on anaerobic processes to capture methane, which are accomplished by anaerobic methanotrophic archaea (ANME) in consortia. However, no p...
