[13C]bicarbonate labelled from hyperpolarized [1-13C]pyruvate is an in vivo marker of hepatic gluconeogenesis in fasted state

Rolf Gruetter, Arnaud Comment, Josefina Adriana Maria Bastiaansen, Hikari Ananda Infinity Yoshihara, Emine Can

Hyperpolarized [1-13C]pyruvate enables direct in vivo assessment of real-time liver enzymatic activities by 13C magnetic resonance. However, the technique usually requires the injection of a highly supraphysiological dose of pyruvate. We herein demonstrate ...

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 ...

Effect of minor amounts of beta-calcium pyrophosphate and hydroxyapatite on the physico-chemical properties and osteoclastic resorption of beta-tricalcium phosphate cylinders

Paul Bowen, Gabrielle Anne Laguisma Sblendorio

beta-Tricalcium Phosphate (beta-TCP), one of the most used bone graft substitutes, may contain up to 5 wt% foreign phase according to standards. Typical foreign phases include beta-calcium pyrophosphate (beta-CPP) and hydroxyapatite (HA). Currently, the ef ...

Assessment of Aspartate and Bicarbonate Produced From Hyperpolarized [1-13C]Pyruvate as Markers of Renal Gluconeogenesis

Arnaud Comment, Hikari Ananda Infinity Yoshihara

As both a consumer and producer of glucose, the kidney plays a significant role in glucose homeostasis. Measuring renal gluconeogenesis requires invasive techniques, and less invasive methods would allow renal gluconeogenesis to be measured more routinely. ...

Acute RyR1 Ca2+ leak enhances NADH-linked mitochondrial respiratory capacity

Johan Auwerx, Umberto De Marchi

Sustained ryanodine receptor (RyR) Ca2+ leak is associated with pathological conditions such as heart failure or skeletal muscle weakness. We report that a single session of sprint interval training (SIT), but not of moderate intensity continuous training ...

Noninvasive rapid detection of metabolic adaptation in activated human T lymphocytes by hyperpolarized 13C magnetic resonance

Mor-Miri Mishkovsky, Arnaud Comment, Hikari Ananda Infinity Yoshihara, Nicolas Kunz, Emine Can

The metabolic shift induced in human CD4+ T lymphocytes by stimulation is characterized by an upregulation of glycolysis, leading to an augmentation in lactate production. This adaptation has already been highlighted with various techniques and reported in ...

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 ...

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 ...
