Metabolic dependencies of metastasis-initiating cells in breast cancer

Metastasis is the process by which cancer cells from the primary tumor travel through the blood stream to generate a secondary tumor site in a distant organ. Although very few cells are able to make this journey, the resulting effects are dire since most c ...

Performance and reproducibility of C-13 and N-15 hyperpolarization using a cryogen-free DNP polarizer

Hikari Ananda Infinity Yoshihara, Arianna Ferrari

The setup, operational procedures and performance of a cryogen-free device for producing hyperpolarized contrast agents using dissolution dynamic nuclear polarization (dDNP) in a preclinical imaging center is described. The polarization was optimized using ...

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 ...

Role of glutathione S-transferases and the mercapturic acid pathway in the biotransformation potential of two zebrafish (Danio rerio) test systems: early life stages and PAC2 cells

Alena Tierbach

Zebrafish (Danio rerio) early life stages provide an important model for chemical risk assessment due to their genetic similarity to humans and the availability of well-established high-throughput techniques. Cells isolated from zebrafish conserve all thes ...

N-acetylaspartate availability is essential for juvenile survival on fat-free diet and determines metabolic health

Johan Auwerx, Dina Hofer

N-acetylaspartate (NAA) is synthesized by aspartate N-acetyltransferase (gene: Nat8l) from acetyl-coenzyme A and aspartate. In the brain, NAA is considered an important energy metabolite for lipid synthesis. However, the role of NAA in peripheral tissues r ...

Chemical genetic screen identifies Gapex-5/GAPVDI and STBD1 as novel AMPK substrates

Kei Sakamoto, Maria Deak, Caterina Collodet, Susanne Seitz

AMP-activated protein kinase (AMPK) is a key regulator of cellular energy homeostasis, acting as a sensor of energy and nutrient status. As such, AMPK is considered a promising drug target for treatment of medical conditions particularly associated with me ...

Structural basis for regulation of human acetyl-CoA carboxylase

Henning Paul-Julius Stahlberg, Yakir Guri

Acetyl-CoA carboxylase catalyses the ATP-dependent carboxylation of acetyl-CoA, a rate-limiting step in fatty acid biosynthesis(1,2). Eukaryotic acetyl-CoA carboxylases are large, homodimeric multienzymes. Human acetyl-CoA carboxylase occurs in two isoform ...

Renal metabolism of hyperpolarized [1-13C]aspartate

Hikari Ananda Infinity Yoshihara

Aspartic acid is involved in several central metabolic pathways, including gluconeogenesis, the urea cycle, de novo nucleotide synthesis, the malate-aspartate shuttle, and via transmination the TCA cycle. The conversion in vivo of hyperpolarized [1-13C]pyr ...

Energy metabolism in the rat cortex under thiopental anaesthesia measured

Rolf Gruetter, João Miguel das Neves Duarte, Nathalie Just, Sarah Catherine Sonnay

Barbiturates, commonly used as general anaesthetics, depress neuronal activity and thus cerebral metabolism. Moreover, they are likely to disrupt the metabolic support of astrocytes to neurons, as well as the uptake of nutrients from circulation. By employ ...

Measuring changes in substrate utilization in the myocardium in response to fasting using hyperpolarized [1-(13)C]butyrate and [1-(13)C]pyruvate

Arnaud Comment, Josefina Adriana Maria Bastiaansen

Cardiac dysfunction is often associated with a shift in substrate preference for ATP production. Hyperpolarized (HP) (13)C magnetic resonance spectroscopy (MRS) has the unique ability to detect real-time metabolic changes in vivo due to its high sensitivit ...
