Dissecting the role of the asparagine synthesis in acute liver injury

Amino acids are some of the main building stones of life used in a variety of biological processes, such as protein synthesis, energy metabolism or even as precursors for hormone synthesis. How-ever, some of them also participate and coordinate certain cel ...

Probiotics and gut microbiome-Prospects and challenges in remediating heavy metal toxicity

Edgard Gnansounou, Ranjna Sirohi

The gut microbiome, often referred to as "super organ", comprises up to a hundred trillion microorganisms, and the species diversity may vary from person to person. They perform a decisive role in diverse biological functions related to metabolism, immunit ...

Methylation of arsenic by single-species and soil-derived microbial cultures

Karen Elda Viacava Romo

Arsenic (As) is simultaneously a ubiquitous and a toxic element. Arsenic is subject to bio-transformations catalyzed by microorganisms constituting the As biogeochemical cycle. The primordial Earth was devoid of oxygen, exposing life to the highly mobile a ...

Augmented mitochondrial energy metabolism is an early response to chronic glucose stress in human pancreatic beta cells

Loïc Dayon, Andreas Wiederkehr, Sofia Moco, Isabelle Chareyron

Aims/hypothesis In islets from individuals with type 2 diabetes and in islets exposed to chronic elevated glucose, mitochondrial energy metabolism is impaired. Here, we studied early metabolic changes and mitochondrial adaptations in human beta cells durin ...

MicroRNA-382 silencing induces a mitonuclear protein imbalance and activates the mitochondrial unfolded protein response in muscle cells

Johan Auwerx, Pénélope Andreux, Xu Wang, Norman Lionel Moullan

Proper mitochondrial function plays a central role in cellular metabolism. Various diseases as well as aging are associated with diminished mitochondrial function. Previously, we identified 19 miRNAs putatively involved in the regulation of mitochondrial m ...

Non-invasive diagnosis and metabolic consequences of congenital portosystemic shunts in C57BL/6 J mice

Hongxia Lei, Ana Francisca Leal Silva Soares

This study demonstrates the suitability of magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) for the imaging of congenital portosystemic shunts (PSS) in mice, a vascular abnormality in which mesenteric blood bypasses the liver and i ...

Facing The Unknown: Suggesting Alternative Novel Biochemistry in Escherichia coli and Saccharomyces cerevisiae

Vassily Hatzimanikatis, Meriç Ataman, Noushin Hadadi

While advances in genome sequencing have greatly facilitated the inference of metabolic networks, the presence of unknown biochemistry in the organisms still challenges the analysis and understanding of metabolism. Even for one of the most known organism l ...

Diurnal Oscillations in Liver Mass and Cell Size Accompany Ribosome Assembly Cycles

Frédéric Bruno Martin Gachon, Daniel Alain Dominique Marie Mauvoisin, Jingkui Wang

The liver plays a pivotal role in metabolism and xenobiotic detoxification, processes that must be particularly efficient when animals are active and feed. A major question is how the liver adapts to these diurnal changes in physiology. Here, we show that, ...
