The mitochondrial calcium uniporter (MCU) activates mitochondrial respiration and enhances mobility by regulating mitochondrial redox state

Vincenzo Sorrentino

Regulation of mitochondrial redox balance is emerging as a key event for cell signaling in both physiological and pathological conditions. However, the link between the mitochondrial redox state and the modulation of these conditions remains poorly defined ...

Article Structure and functionality of a multimeric human COQ7:COQ9 complex

Matteo Dal Peraro, Luciano Andres Abriata

Coenzyme Q (CoQ) is a redox-active lipid essential for core metabolic pathways and antioxidant defense. CoQ is synthesized upon the mitochondrial inner membrane by an ill-defined "complex Q" metabolon. Here, we present structure-function analyses of a lipi ...

Adsorption Behavior of the Coenzyme NADH at the Carbon/ Electrolyte Interface Determined by Neutron Reflectometry

Mary Hannah Wood

The adsorption behavior of beta-nicotinamide adenine dinucleotide (NADH) at the carbon/electrolyte interface has been studied using a combination of neutron reflectometry (NR) and solution depletion isotherms. Coupling the NR technique with an electrochemi ...

Differential role of nicotinamide adenine dinucleotide deficiency in acute and chronic kidney disease

Johan Auwerx, Adrienne Joëlle Laurence Mottis, Elena Katsyuba

Background. Nicotinamide adenine dinucleotide (NAD(+)) is a ubiquitous coenzyme involved in electron transport and a cosubstrate for sirtuin function. NAD(+) deficiency has been demonstrated in the context of acute kidney injury (AKI). Methods. We studied ...

Generation of hydroxyl radical during chlorination of hydroxyphenols and natural organic matter extracts

Urs von Gunten, Eva Maria Rodriguez Franco

The generation of hydroxyl radicals ((OH)-O-center dot) during the chlorination of air saturated solutions of different hydroxyphenols (hydroquinone, resorcinol, catechol, gallic and tannic acids) at pH 7 has been determined by the formation of phenol (in ...

An Isoprene Lipid-Binding Protein Promotes Eukaryotic Coenzyme Q Biosynthesis

Matteo Dal Peraro, Deniz Aydin

The biosynthesis of coenzyme Q presents a paradigm for how cells surmount hydrophobic barriers in lipid biology. In eukaryotes, CoQ precursors-among nature's most hydrophobic molecules-must somehow be presented to a series of enzymes peripherally associate ...

Characterization of Coenzyme Q Biosynthesis Proteins through Integrative Modeling at the Protein-Membrane Interface

Deniz Aydin

Integral and peripheral membrane proteins account for one-third of the human proteome, and they are estimated to represent the target for over 50% of modern medicinal drugs. Despite their central role in medicine, the complex, heterogeneous and dynamic nat ...

Cerebellar Ataxia and Coenzyme Q Deficiency through Loss of Unorthodox Kinase Activity

Matteo Dal Peraro, Deniz Aydin

The UbiB protein kinase-like (PKL) family is widespread, comprising one-quarter of microbial PKLs and five human homologs, yet its biochemical activities remain obscure. COQ8A (ADCK3) is a mammalian UbiB protein associated with ubiquinone (CoQ) biosynthesi ...

Deciphering the Role of LRH-1 in Liver Intermediary Metabolism and Cancer

Pan Xu

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer death worldwide. Gaining insight into the molecular pathways involved in the development of HCC is hence a prerequisite to design and develop novel and effective therapeutic strategies. ...

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

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 ...

Structural Role of RKS Motifs in Chromatin Interactions: A Molecular Dynamics Study of HP1 Bound to a Variably Modified Histone Tail

Efthimios Kaxiras

The current understanding of epigenetic signaling assigns a central role to post-translational modifications that occur in the histone tails. In this context, it has been proposed that methylation of K9 and phosphorylation of S10 in the tail of histone H3 ...

Effect of coenzyme Q10 and vitamin E on brain energy metabolism in the animal model of Huntington's disease

The neuropathological and clinical symptoms of Huntington's disease (HD) can be simulated in animal model with systemic administration of 3-nitropropionic acid (3-NP). Energy defects in HD could be ameliorated by administration of coenzyme Q10 (CoQ10), cre ...
