Effects of aerobic training on pyruvate dehydrogenase and pyruvate dehydrogenase kinase in human skeletal muscle [PDF]

The Journal of Physiology, 2004
This study examined the effects of short‐ and long‐term aerobic training on the stable up‐regulation of pyruvate dehydrogenase (PDH) and PDH kinase (PDK) in human skeletal muscle. We hypothesized that 8 weeks, but not 1 week, of aerobic training would increase total PDH (PDHt) and PDK activities compared to pretraining, and this would be detectable at ...

Variation in the organization and subunit composition of the mammalian pyruvate dehydrogenase complex E2/E3BP core assembly [PDF]

, 2011
The final version of this article is available at the link below.Crucial to glucose homoeostasis in humans, the hPDC (human pyruvate dehydrogenase complex) is a massive molecular machine comprising multiple copies of three distinct enzymes (E1–E3) and an

Warburg effect hypothesis in autism Spectrum disorders

Molecular Brain, 2018
Autism spectrum disorder (ASD) is a neurodevelopmental disease which is characterized by a deficit in social interactions and communication with repetitive and restrictive behavior. In altered cells, metabolic enzymes are modified by the dysregulation of

Metabolic Flexibility in Cancer: Targeting the Pyruvate Dehydrogenase Kinase:Pyruvate Dehydrogenase Axis

Molecular Cancer Therapeutics, 2019
Cancer cells use alterations of normal metabolic processes to sustain proliferation indefinitely. Transcriptional and posttranscriptional control of the pyruvate dehydrogenase kinase (PDK) family is one way in which cancer cells alter normal pyruvate ...

Melatonin Therapy Modulates Cerebral Metabolism and Enhances Remyelination by Increasing PDK4 in a Mouse Model of Multiple Sclerosis

Frontiers in Pharmacology, 2019
Metabolic disturbances have been implicated in demyelinating diseases including multiple sclerosis (MS). Melatonin, a naturally occurring hormone, has emerged as a potent neuroprotective candidate to reduce myelin loss and improve MS outcomes.

Detecting de novo Hepatic Ketogenesis Using Hyperpolarized [2-13C] Pyruvate

Frontiers in Physiology, 2022
The role of ketones in metabolic health has progressed over the past two decades, moving from what was perceived as a simple byproduct of fatty acid oxidation to a central player in a multiplicity of disease states. Previous work with hyperpolarized (HP)

Evidence that pyruvate dehydrogenase kinase belongs to the ATPase/kinase superfamily [PDF]

Biochemical Journal, 1999
In this study the roles of invariant Asn-247, Asp-282, Gly-284, Gly-286 and Gly-319 of pyruvate dehydrogenase kinase were investigated by site-directed mutagenesis. Recombinant kinases, wild-type, Asn-247Ala, Asp-282Ala, Gly-284Ala, Gly-286Ala and Gly-319Ala, were expressed in bacteria, purified, and characterized. Three mutant kinases, Asn-247Ala, Asp-

Long-term regulation of pyruvate dehydrogenase complex. Evidence that kinase-activator protein (KAP) is free pyruvate dehydrogenase kinase [PDF]

Biochemical Journal, 1991
The kinase-activator protein (KAP) of pyruvate dehydrogenase complex (PDC) has been purified approx. 2250-fold from high-speed supernatants of mitochondrial extracts from the liver of 48 h-starved rats. Purified KAP demonstrates kinase activity towards both the E1 component of PDC and towards a synthetic peptide corresponding to the major ...

Molecular mechanisms of the non-coenzyme action of thiamin in brain. Biochemical, structural and pathway analysis [PDF]

, 2015
Thiamin (vitamin B1) is a pharmacological agent boosting central metabolism through the action of the coenzyme thiamin diphosphate (ThDP). However, positive effects, including improved cognition, of high thiamin doses in neurodegeneration may be ...
