The two metabolic sensors AMPK and SIRT1 take center stage as Fulco et al. reveal, in this issue of Developmental Cell, the signaling mechanism by which low glucose prevents the correct development of the myogenic program. These observations may hold some ...

Accumulating evidence indicates that biological aging can be accelerated by environmental exposures, collectively called the ‘exposome’. The skin, as the largest and most exposed organ, can be viewed as a ‘window’ for the deep exploration of the exposome a ...

The metabolic impact of the common peroxisome proliferator-activated receptor gamma isoform 2 (PPARgamma2) variant Pro12Ala in human populations has been widely debated. We demonstrate, using a Pro12Ala knockin model, that on chow diet, Ala/Ala mice are le ...

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 ...

Context: Elevating nicotinamide adenine dinucleotide (NAD+) levels systemically improves metabolic health, which can be accomplished via nicotinamide riboside (NR). Previously, it was demonstrated that NR supplementation in high-fat-diet (HFD)-fed mice dec ...

Many genes and pathways have been linked to aging, yet our understanding of underlying molecular mechanisms is still lacking. Here, we measure changes in the transcriptome, histone modifications, and DNA methylome in three metabolic tissues of adult and ag ...

The maintenance of metabolic homeostasis requires the well-orchestrated network of several pathways of glucose, lipid and amino acid metabolism. Mitochondria integrate these pathways and serve not only as the prime site of cellular energy harvesting but al ...

Nicotinamide adenine dinucleotide (NAD(+)) is a co-substrate for several enzymes, including the sirtuin family of NAD(+)-dependent protein deacylases. Beneficial effects of increased NAD(+) levels and sirtuin activation on mitochondrial homeostasis, organi ...

Sirt5, localized in the mitochondria, is a member of sirtuin family of NAD(+)-dependent deacetylases. Sirt5 was shown to deacetylate and activate carbamoyl phosphate synthase 1. Most recently, Sirt5 was reported to be the predominant protein desuccinylase ...

The mitochondrial unfolded protein response (UPRmt) is a promising pharmacological target for aging and age-related diseases. However, the integrative analysis of the impact of UPRmt activation on different signaling layers in animals with different geneti ...

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 ...

In recent years, the role of acetylation has gained ground as an essential modulator of intermediary metabolism in skeletal muscle. Imbalance in energy homeostasis or chronic cellular stress, due to diet, aging, or disease, translate into alterations in th ...

Objective: Strategies improving skeletal muscle mitochondrial capacity are commonly paralleled by improvements in (metabolic) health. We and others previously identified microRNAs regulating mitochondrial oxidative capacity, but data in skeletal muscle are ...

SIRT7 is a NAD(+)-dependent deacetylase that controls important aspects of metabolism, cancer, and bone formation. However, the molecular targets and functions of SIRT7 in the kidney are currently unknown. In silico analysis of kidney transcripts of the BX ...

Lysosomes are central platforms for not only the degradation of macromolecules but also the integration of multiple signaling pathways. However, whether and how lysosomes mediate the mitochondrial stress response (MSR) remain largely unknown. Here, we demo ...

Mitochondrial activity is controlled by proteins encoded by both nuclear and mitochondrial DNA. Here, we identify Sirt7 as a crucial regulator of mitochondrial homeostasis. Sirt7 deficiency in mice induces multisystemic mitochondrial dysfunction, which is ...

Reversible acetylation was initially described as an epigenetic mechanism regulating DNA accessibility. Since then, this process has emerged as a controller of histone and nonhistone acetylation that integrates key physiological processes such as metabolis ...

The present invention relates to an inhibitor of sphingolipids for use in the treatment or prevention of an aging related-disease and/or aging. ...

Haematopoietic stem cells (HSCs) differ from their committed progeny by relying primarily on anaerobic glycolysis rather than mitochondrial oxidative phosphorylation for energy production. However, whether this change in the metabolic program is the cause ...
