Amoebocytes facilitate efficient carbon and nitrogen assimilation in the Cassiopea -Symbiodiniaceae symbiosis

Anders Meibom, Stéphane Laurent Escrig, Nils Rädecker, Louise Helene Soegaard Jensen, Niclas Heidelberg Lyndby, Sandrine Denise Françoise Bessette, Michael Kühl

The upside-down jellyfish Cassiopea engages in symbiosis with photosynthetic microalgae that facilitate uptake and recycling of inorganic nutrients. By con- trast to most other symbiotic cnidarians, algal endosymbionts in Cassiopea are not restricted to th ...

Modeling, predicting and mining metabolism at atom-level resolution

Jasmin Maria Hafner

Living organisms can catalyze many thousands of biochemical reactions that they use to convert energy and matter, which provides them with the essentials for life. The sum of these chemical reactions happening in an organism is called metabo-lism. Understa ...

Crosstalk between Drp1 phosphorylation sites during mitochondrial dynamics and metabolic adaptation

Miriam Valera Alberni

Mitochondria are highly dynamics organelles that undergo coordinated cycles of fission and fusion, referred to as mitochondrial dynamics. Mitochondrial dynamics regulate mitochondrial bioenergetics and allow cells to adapt to changing cellular stresses and ...

Eosinophils regulate adipose tissue inflammation and sustain physical and immunological fitness in old age

Johan Auwerx, Norman Lionel Moullan

Adipose tissue eosinophils (ATEs) are important in the control of obesity-associated inflammation and metabolic disease. However, the way in which ageing impacts the regulatory role of ATEs remains unknown. Here, we show that ATEs undergo major age-related ...

Transient vitamin B5 starving improves mammalian cell homeostasis and protein production

Nicolas Mermod

Maintaining a metabolic steady state is essential for an organism's fitness and survival when confronted with environmental stress, and metabolic imbalance can be reversed by exposing the organism to fasting. Here, we attempted to apply this physiological ...

Modeling metabolic and signaling pathways in cancer cells

Maria Masid Barcon

Cancer is a leading cause of death in the world, and the mechanisms that underlie this disease are still not completely understood. As cancer develops and progresses, cells undergo a diversity of mutations that sustain their rapid proliferation and the eva ...

Endogenous nicotinamide riboside metabolism protects against diet-induced liver damage

Carlos Canto Alvarez, Sofia Moco, Joanna Ratajczak, Miriam Valera Alberni

Supplementation with the NAD(+) precursor nicotinamide riboside (NR) ameliorates and prevents a broad array of metabolic and aging disorders in mice. However, little is known about the physiological role of endogenous NR metabolism. We have previously show ...

Diet modulates cecum bacterial diversity and physiological phenotypes across the BXD mouse genetic reference population

Johan Auwerx, Evan Graehl Williams

The BXD family has become one of the preeminent genetic reference populations to understand the genetic and environmental control of phenotypic variation. Here we evaluate the responses to different levels of fat in the diet using both chow diet (CD, 13-18 ...

Investigating the deregulation of metabolic tasks via Minimum Network Enrichment Analysis (MiNEA) as applied to nonalcoholic fatty liver disease using mouse and human omics data

Vassily Hatzimanikatis, Vikash Kumar Pandey

Nonalcoholic fatty liver disease (NAFLD) is associated with metabolic syndromes spanning a wide spectrum of diseases, from simple steatosis to the more complex nonalcoholic steatohepatitis. To identify the deregulation that occurs in metabolic processes at ...

Discovery and validation of temporal patterns involved in human brain ketometabolism in cerebral microdialysis fluids of traumatic brain injury patients

Sarah Catherine Sonnay, Anirikh Chakrabarti, Nicolas Christinat, Mojgan Masoodi

Background: Traumatic brain injury (TBI) is recognized as a metabolic disease, characterized by acute cerebral glucose hypo-metabolism. Adaptive metabolic responses to TBI involve the utilization of alternative energy substrates, such as ketone bodies. Cer ...

Feasibility of neurochemically profiling mouse embryonic brain and its development in utero using 1 H MRS at 14.1 T

Hongxia Lei, Sébastien Robert Victor Herzig

We aimed to evaluate the feasibility of neurochemical profiling of embryonic mouse brain developments in utero and to seek potential in vivo evidence of an energy shift in a mitochondrial pyruvate carrier 1 (MPC1) deficient mouse model. C57BL/6 embryonic m ...

Circadian Rhythms and Mitochondria: Connecting the Dots

Carlos Canto Alvarez, Miriam Valera Alberni

Circadian rhythms provide a selective advantage by anticipating organismal nutrient needs and guaranteeing optimal metabolic capacity during active hours. Impairment of circadian rhythms is associated with increased risk of type 2 diabetes and emerging evi ...
