Control of intestinal stem cell function and proliferation by mitochondrial pyruvate metabolism. [PDF]

, 2017
Most differentiated cells convert glucose to pyruvate in the cytosol through glycolysis, followed by pyruvate oxidation in the mitochondria. These processes are linked by the mitochondrial pyruvate carrier (MPC), which is required for efficient ...

Efficient production of pyruvate from DL-lactate by the lactate-utilizing strain Pseudomonas stutzeri SDM. [PDF]

PLoS ONE, 2012
BACKGROUND: The platform chemical lactate is currently produced mainly through the fermentation of sugars presented in biomass. Besides the synthesis of biodegradable polylactate, lactate is also viewed as a feedstock for the green chemistry of the ...

Mitochondrial Pyruvate Carrier 1 Promotes Peripheral T Cell Homeostasis through Metabolic Regulation of Thymic Development

Cell Reports, 2020
Summary: Metabolic pathways regulate T cell development and function, but many remain understudied. Recently, the mitochondrial pyruvate carrier (MPC) was identified as the transporter that mediates pyruvate entry into mitochondria, promoting pyruvate ...

The Role of Pyruvate Dehydrogenase Kinase in Diabetes and Obesity [PDF]

Diabetes & Metabolism Journal, 2014
The pyruvate dehydrogenase complex (PDC) is an emerging target for the treatment of metabolic syndrome. To maintain a steady-state concentration of adenosine triphosphate during the feed-fast cycle, cells require efficient utilization of fatty acid and ...

Metabolic checkpoint of ferroptosis resistance

Molecular & Cellular Oncology, 2021
The metabolic checkpoint of ferroptosis remains obscure. We find that glucose favors system xc− inhibitor-induced ferroptosis by activating pyruvate oxidation, thereby promoting fatty acid synthesis and subsequent lipid peroxidation.

Detection of increased pyruvate dehydrogenase flux in the human heart during adenosine stress test using hyperpolarized [1-13C]pyruvate cardiovascular magnetic resonance imaging

Journal of Cardiovascular Magnetic Resonance, 2022
Background Hyperpolarized (HP) [1-13C]pyruvate cardiovascular magnetic resonance (CMR) imaging can visualize the uptake and intracellular conversion of [1-13C]pyruvate to either [1-13C]lactate or 13C-bicarbonate depending on the prevailing metabolic ...

Integrative structure of a 10-megadalton eukaryotic pyruvate dehydrogenase complex from native cell extracts

Cell Reports, 2021
Summary: The pyruvate dehydrogenase complex (PDHc) is a giant enzymatic assembly involved in pyruvate oxidation. PDHc components have been characterized in isolation, but the complex’s quaternary structure has remained elusive due to sheer size ...

Inhibition of the mitochondrial pyruvate carrier protects from excitotoxic neuronal death. [PDF]

, 2017
Glutamate is the dominant excitatory neurotransmitter in the brain, but under conditions of metabolic stress it can accumulate to excitotoxic levels.

Fatty acid challenge shifts cellular energy metabolism in a substrate-specific manner in primary bovine neonatal hepatocytes

Scientific Reports, 2023
Adipose tissue mobilization increases circulating fatty acid (FA) concentrations, leads to increased hepatic FA uptake, and influences hepatic metabolism.

High cycling cadence reduces carbohydrate oxidation at given low intensity metabolic rate [PDF]

, 2014
Cycling cadence (RPM)-related differences in blood lactate concentration (BLC) increase with increasing exercise intensity, whilst corresponding divergences in oxygen uptake (VO2) and carbon dioxde production (VCO2) decrease.
