Regulation and impact of TERRA R-loops at human telomeres

Telomeres are the nucleoprotein structures found at the ends of linear chromosomes. They ensure that the termini of chromosomes are not inappropriately recognized as sites of DNA damage, and are therefore crucial for genome stability. In spite of the heter ...

Gamified Motor Training With Tangible Robots in Older Adults: A Feasibility Study and Comparison With the Young

Pierre Dillenbourg, Friedhelm Christoph Hummel, Wafa Monia Benkaouar Johal, Maximilian Jonas Wessel, Ayberk Özgür, Jennifer Kaitlyn Olsen

Background: An increasing lifespan and the resulting change in our expectations of later life stages are dependent on a good health state. This emphasizes the importance of the development of strategies to further strengthen healthy aging. One important as ...

Brain NAD Is Associated With ATP Energy Production and Membrane Phospholipid Turnover in Humans

Rolf Gruetter, Lijing Xin, Özlem Ipek, Maya Shevlyakova

The brain requires a large amount of energy, mostly derived from the metabolism of glucose, which decreases substantially with age and neurological diseases. While mounting evidence in model organisms illustrates the central role of brain nicotinamide aden ...

Cross-species functional modules link proteostasis to human normal aging

Johan Auwerx, Hao Li, Vincenzo Sorrentino, Andrea Komljenovic

The evolutionarily conserved nature of the few well-known anti-aging interventions that affect lifespan, such as caloric restriction, suggests that aging-related research in model organisms is directly relevant to human aging. Since human lifespan is a com ...

Systems Phytohormone Responses to Mitochondrial Proteotoxic Stress

Johan Auwerx, Xu Wang

Mitochondrial function is controlled by two separate genomes. This feature makes mitochondria prone to proteotoxic stress when a stoichiometric imbalance occurs in the protein complexes that perform oxidative phosphorylation, which consist of both nucleara ...

Enhancing mitochondrial proteostasis reduces amyloid-beta proteotoxicity

Johan Auwerx, Davide D'Amico, Adrian Schmid, 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 ...

Tandem affinity purification of AtTERT reveals putative interaction partners of plant telomerase in vivo

Jana Majerská

The life cycle of telomerase involves dynamic and complex interactions between proteins within multiple macromolecular networks. Elucidation of these associations is a key to understanding the regulation of telomerase under diverse physiological and pathol ...

Red blood cells ageing markers: a multi-parametric analysis

Gerardo Turcatti, Niels Erik Lion, Benjamin Rappaz, David Crettaz, Michel Prudent, Manon Sandra Bardyn

Background. Red blood cells collected in citrate-phosphate-dextrose can be stored for up to 42 days at 4 degrees C in saline-adenine-glucose-mannitol additive solution. During this controlled, but nevertheless artificial, ex vivo ageing, red blood cells ac ...

On-chip microfluidic biocommunication assay for studying male-induced demise in C. elegans hermaphrodites

Martinus Gijs, Thomas Lehnert, Matteo Cornaglia, Li Dong

Like other animals, C. elegans nematodes have the ability to socially interact and to communicate through exchange and sensing of small soluble signaling compounds that help them cope with complex environmental conditions. For the time being, worm biocommu ...

Two Conserved Histone Demethylases Regulate Mitochondrial Stress-Induced Longevity

Johan Auwerx, Laurent Mouchiroud, Evan Graehl Williams, Virginija Jovaisaite

Across eukaryotic species, mild mitochondrial stress can have beneficial effects on the lifespan of organisms. Mitochondrial dysfunction activates an unfolded protein response (UPR(mt)), a stress signaling mechanism designed to ensure mitochondrial homeost ...
