Aging and sarcopenia associate with specific interactions between gut microbes, serum biomarkers and host physiology in rats

Sonia Karaz, Anirikh Chakrabarti, Mojgan Masoodi, Alice Pannerec, Jay Siddharth

The microbiome has been demonstrated to play an integral role in the maintenance of many aspects of health that are also associated with aging. In order to identify areas of potential exploration and intervention, we simultaneously characterized age-relate ...

The chromatin remodeling factor ISW-1 integrates organismal responses against nuclear and mitochondrial stress

Johan Auwerx, Maroun Bou Sleiman

Age-associated changes in chromatin structure have a major impact on organismal longevity. Despite being a central part of the ageing process, the organismal responses to the changes in chromatin organization remain unclear. Here we show that moderate dist ...

Quantitative telomeric chromatin isolation protocol for human cells

Joachim Lingner, Sophie Redon, Jana Majerská

The ends of eukaryotic chromosomes, known as telomeres, consist of repetitive DNA sequences, multiple proteins and noncoding RNAs. Telomeres are dynamic structures that play crucial roles as guardians of genome stability and tumor suppressors. Defects in t ...

Allosteric cross-talk in chromatin can mediate drug-drug synergy

Paul Joseph Dyson, Ursula Röthlisberger, Tina Riedel, Giulia Palermo

Exploitation of drug-drug synergism and allostery could yield superior therapies by capitalizing on the immensely diverse, but highly specific, potential associated with the biological macromolecular landscape. Here we describe a drug-drug synergy mediated ...

Enhancing mitochondrial proteostasis reduces amyloid-beta proteotoxicity

Johan Auwerx, Davide D'Amico, Adrian Schmid, Mario Romani, Norman Lionel Moullan, Vincenzo Sorrentino, Hongbo Zhang, Francesca Potenza, Solene Rietsch

Alzheimer's disease is a common and devastating disease characterized by aggregation of the amyloid-beta peptide. However, we know relatively little about the underlying molecular mechanisms or how to treat patients with Alzheimer's disease. Here we provid ...

Mitochondria and Epigenetics Crosstalk in Homeostasis and Stress

Johan Auwerx

Through epigenetic mechanisms cells integrate environmental stimuli to fine-tune gene expression levels. Mitochondrial function is essential to provide the intermediate metabolites necessary to generate and modify epigenetic marks in the nucleus, which in ...

Combination of ruthenium(II)-arene complex [Ru(eta(6)-p-cymene)Cl-2(pta)] (RAPTA-C) and the epidermal growth factor receptor inhibitor erlotinib results in efficient angiostatic and antitumor activity

Paul Joseph Dyson, Patrycja Nowak-Sliwinska, Ume-Gulsoom Abdul, Patrick Meraldi

Ruthenium-based compounds show strong potential as anti-cancer drugs and are being investigated as alternatives to other well-established metal-based chemotherapeutics. The organometallic compound [Ru(eta(6)-p-cymene) Cl-2(pta)], where pta = 1,3,5-triaza-7 ...

Multi-factorial approach in aging research

Michael Herzog, Aaron Michael Clarke, Albulena Jashari-Shaqiri

Aging affects all kinds of human functions including perception and cognition. In most perceptual studies, one paradigm is tested and it is usually found that older participants perform worse than younger participants. Implicitly, these results are taken a ...

Multi-factorial approach in aging research

Michael Herzog, Aaron Michael Clarke, Albulena Jashari-Shaqiri

The developed world is aging faster than ever before. Even in the absence of neurodegenerative disease, aging affects all kinds of human functions including perception and cognition. In most perceptual studies, one paradigm is tested and it is usually foun ...

Nicotinamide riboside kinases display redundancy in mediating nicotinamide mononucleotide and nicotinamide riboside metabolism in skeletal muscle cells

Carlos Canto Alvarez, Joanna Ratajczak

Objective: Augmenting nicotinamide adenine dinucleotide (NAD(+)) availability may protect skeletal muscle from age-related metabolic decline. Dietary supplementation of NAD(+) precursors nicotinamide mononucleotide (NMN) and nicotinamide riboside (NR) appe ...
