TL;DR: It is demonstrated how the intracellular concentrations of metabolites can reveal phenotypes for proteins active in metabolic regulation, and this approach to functional analysis, using comparative metabolomics, is called FANCY—an abbreviation for functional analysis by co-responses in yeast.

TL;DR: In lymphoma-bearing mice injected intravenously with hyperpolarized [1-13C]pyruvate, it is shown that the lactate dehydrogenase–catalyzed flux of 13C label between the carboxyl groups of pyruvates and lactate in the tumor can be measured using 13C magnetic resonance spectroscopy and spectroscopic imaging, and that this flux is inhibited within 24 h of chemotherapy.

TL;DR: The pentose phosphate pathway (PPP) is a fundamental component of cellular metabolism as discussed by the authors, which shares reactions with the Entner-Doudoroff pathway and the Calvin cycle and divides into an oxidative and non-oxidative branch.

TL;DR: Tissue pH can be imaged in vivo from the ratio of the signal intensities of hyperpolarized bicarbonate and 13CO2 following intravenous injection of hyperPolarized H13CO3-.

TL;DR: Experts assembled to review, debate and summarize the challenges of IB validation and qualification produced 14 key recommendations for accelerating the clinical translation of IBs, which highlight the role of parallel (rather than sequential) tracks of technical validation, biological/clinical validation and assessment of cost-effectiveness.
