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 ...

Fluorometric procedures for measuring triglyceride concentrations in small amounts of tissue and plasma.

Journal of Lipid Research, 1988
It has been previously shown that triglycerides can be specifically hydrolyzed by lipase from Rhizopus arrhizus in the presence of hog liver esterase and sodium dodecyl sulfate.

Astrocytes and neurons communicate via a monocarboxylic acid shuttle [PDF]

, 2020
Since formulation of the Astrocyte-Neuron Lactate Shuttle (ANLS) hypothesis in 1994, the hypothesis has provoked criticism and debate. Our review does not criticise, but rather integrates experimental data characterizing proton-linked monocarboxylate ...

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 ...

Incorporating expression data in metabolic modeling: a case study of lactate dehydrogenase

, 2005
Integrating biological information from different sources to understand cellular processes is an important problem in systems biology. We use data from mRNA expression arrays and chemical kinetics to formulate a metabolic model relevant to K562 ...

miRNAs link metabolic reprogramming to oncogenesis [PDF]

, 2013
The most profound biochemical phenotype of cancer cells is their ability to metabolize glucose to lactate, even under aerobic conditions. This alternative metabolic circuitry is sufficient to support the biosynthetic and energy requirements for cancer ...

Identifcation of small molecule enzyme inhibitors as broad-spectrum anthelmintics [PDF]

, 2019
Targeting chokepoint enzymes in metabolic pathways has led to new drugs for cancers, autoimmune disorders and infectious diseases. This is also a cornerstone approach for discovery and development of anthelmintics against nematode and flatworm parasites.

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-

The transglutaminase type 2 and pyruvate kinase isoenzyme M2 interplay in autophagy regulation [PDF]

, 2015
Autophagy is a self-degradative physiological process by which the cell removes worn-out or damaged components. Constant at basal level it may become highly active in response to cellular stress. The type 2 transglutaminase (TG2), which accumulates under

Reversing tozasertib resistance in glioma through inhibition of pyruvate dehydrogenase kinases

Molecular Oncology, 2022
Acquired resistance to conventional chemotherapeutic agents limits their effectiveness and can cause cancer treatment to fail. Because enzymes in the aurora kinase family are vital regulators of several mitotic events, we reasoned that targeting these ...
