Modelling the metabolism of the polyphosphate-accumulating organism Candidatus Accumulibacter

Wastewater resulting from human activities must be treated to minimize the impact on the receiving ecosystems. One of such potential impacts in lakes and other water bodies is eutrophication, an excessive increase in their nitrogen and phosphorus content. ...

Conditional essentiality of the 11-subunit complex I-like enzyme in strict anaerobes: the case of Desulfitobacterium hafniense strain DCB-2

Christof Holliger, Julien Maillard, Romain Hamelin, Florence Armand, Mathilde Stéphanie Willemin

In oxidative phosphorylation, respiratory complex I serves as an entry point in the electron transport chain for electrons generated in catabolic processes in the form of NADH. An ancestral version of the complex, lacking the NADH-oxidising module, is enco ...

Mechanistic Insights into the Multiple Functions of Niacinamide: Therapeutic Implications and Cosmeceutical Applications in Functional Skincare Products

Philippe Abdel Sayed

Niacinamide (or nicotinamide) is a small-molecule hydrosoluble vitamin with essential metabolic functions in mammalian cells. Niacinamide has become a key functional ingredient in diverse skincare products and cosmetics. This vitamin plays a pivotal role i ...

A Cobalt Nanocatalyst for the Hydrogenation and Oxidative Dehydrogenation of N-heterocycles

Paul Joseph Dyson, Yelin Hu, Mingyang Liu

Catalytic hydrogenation and oxidative dehydrogenation of N-heterocycles to produce tetrahydroquinoline and quinoline derivatives are important reactions of particular importance in the agrochemical and pharmaceutical industries. Herein, we report earth-abu ...

Lipid biosynthesis enzyme Agpat5 in AgRP-neurons is required for insulin-induced hypoglycemia sensing and glucagon secretion

Maxime Jan

The counterregulatory response to hypoglycemia that restores normal blood glucose levels is an essential physiological function. It is initiated, in large part, by incompletely characterized brain hypoglycemia sensing neurons that trigger the secretion of ...

Article Multi-omics analysis identifies essential regulators of mitochondrial stress response in two wild-type C. elegans strains

Johan Auwerx, Maroun Bou Sleiman, Yang Li, Wen Gao, Amélia Lalou, Gaby El Alam, Kevin Sebastiaan Hof

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 ...

Mitochondrial copper depletion suppresses triple-negative breast cancer in mice

Elena Goun, Arkadiy Bazhin

Depletion of mitochondrial copper, which shifts metabolism from respiration to glycolysis and reduces energy production, is known to be effective against cancer types that depend on oxidative phosphorylation. However, existing copper chelators are too toxi ...

Foliar respiration is related to photosynthetic, growth and carbohydrate response to experimental drought and elevated temperature

Charlotte Grossiord

Short-term plant respiration (R) increases exponentially with rising temperature, but drought could reduce respiration by reducing growth and metabolism. Acclimation may alter these responses. We examined if species with different drought responses would d ...

Coalescence and directed anisotropic growth of starch granule initials in subdomains of Arabidopsis thaliana chloroplasts

Anders Meibom, Stéphane Laurent Escrig, Christophe Kopp

Starch is the major form of energy storage in plant cells and forms discrete, semi-crystalline granules within plastids. Here the authors use electron tomography and nanoSIMS to show that Arabidopsis starch granules initiate in stromal pockets between thyl ...

Inositol pyrophosphates promote the interaction of SPX domains with the coiled-coil motif of PHR transcription factors to regulate plant phosphate homeostasis

Luciano Andres Abriata

Phosphorus is an essential nutrient taken up by organisms in the form of inorganic phosphate (Pi). Eukaryotes have evolved sophisticated Pi sensing and signaling cascades, enabling them to stably maintain cellular Pi concentrations. Pi homeostasis is regul ...

Natural iron ligands promote a metal-based oxidation mechanism for the Fenton reaction in water environments

César Pulgarin, Stefanos Giannakis

The Fenton reaction is an effective advanced oxidation process occurring in nature and applied in engineering processes toward the degradation of harmful substances, including contaminants of emerging concern. The traditional Fenton application can be rema ...
