Experimental evolution of slowed cognitive aging in Drosophila melanogaster

Reproductive output and cognitive performance decline in parallel during aging, but it is unknown whether this reflects a shared genetic architecture or merely the declining force of natural selection acting independently on both traits. We used experiment ...

Mitochondrial unfolded protein response, its molecular mechanism and physiological impact

Virginija Jovaisaite

Mitochondria are the main producers of ATP, the energy currency of the cell, and they perform a wide array of other fundamental functions. These organelles are essential not only for cellular metabolism, but also for organismal physiology and lifespan. A r ...

The References of References: Enriching Library Catalogs via Domain-Specific Reference Mining

Frédéric Kaplan, Matteo Romanello, Giovanni Colavizza

The advent of large-scale citation services has greatly impacted the retrieval of scientific information for several domains of research. The Humanities have largely remained outside of this shift despite their increasing reliance on digital means for info ...

Serum profiling of healthy aging identifies phospho- and sphingolipid species as markers of human longevity

Martin Kussmann, Sebastiano Collino, Fiona Beguelin

As centenarians well represent the model of healthy aging, there are many important implications in revealing the underlying molecular mechanisms behind such successful aging. By combining NMR metabonomics and shot-gun lipidomics in serum we analyzed metab ...

FOXO3 determines the accumulation of alpha-synuclein and controls the fate of dopaminergic neurons in the substantia nigra

Bernard Schneider, Graham Knott, Juan-Carlos Sarria, Lu Zheng, Emilda Pino, Ryoji Amamoto

Parkinson's disease (PD) is characterized by the selective degeneration of neuronal populations presumably due to pathogenic interactions between aging and predisposing factors such as increased levels of a-synuclein. Here, we genetically modulate the acti ...

Reprint of: Musculoskeletal system in the old age and the demand for healthy ageing biomarkers

Martin Kussmann, Sofia Moco, Sebastiano Collino

Population ageing has emerged as a major demographic trend worldwide due to improved health and longevity. This global ageing phenomenon will have a major impact on health-care systems worldwide due to increased morbidity and greater needs for hospitalizat ...

Mitonuclear protein imbalance as a conserved longevity mechanism

Johan Auwerx, Graham Knott, Laurent Mouchiroud, Richardus Houtkooper, Dongryeol Ryu, Elena Katsyuba, Norman Lionel Moullan

Longevity is regulated by a network of closely linked metabolic systems. We used a combination of mouse population genetics and RNA interference in Caenorhabditis elegans to identify mitochondrial ribosomal protein S5 (Mrps5) and other mitochondrial riboso ...

The NAD(+)/Sirtuin Pathway Modulates Longevity through Activation of Mitochondrial UPR and FOXO Signaling

Johan Auwerx, Kristina Schoonjans, Carlos Canto Alvarez, Laurent Mouchiroud, Richardus Houtkooper, Dongryeol Ryu, Elena Katsyuba, Norman Lionel Moullan, Adrienne Joëlle Laurence Mottis

NAD(+) is an important cofactor regulating metabolic homeostasis and a rate-limiting substrate for sirtuin deacylases. We show that NAD(+) levels are reduced in aged mice and Caenorhabditis elegans and that decreasing NAD(+) levels results in a further red ...

Identification of genetic determinants and pharmacological modulators of mitochondrial function

Pénélope Andreux

Increased life expectancy goes hand in hand with a higher incidence of age-related diseases that affect the nervous and metabolic systems, such as type 2 diabetes, cancer, Parkinson’s and Alzheimer’s disease. These complex diseases are a product of the com ...

Closing the gap between T-cell life span estimates from stable isotope-labeling studies in mice and humans

Istvan Bartha

Quantitative knowledge of the turnover of different leukocyte populations is a key to our understanding of immune function in health and disease. Much progress has been made thanks to the introduction of stable isotope labeling, the state-of-the-art techni ...
