Development of pyruvate dehydrogenase kinase inhibitors in medicinal chemistry with particular emphasis as anticancer agents.
Tam et al., Aomen, Macao. In Drug Discov Today, Sep 2015
Many cancer cells demonstrate a high rate of glucose consumption via glycolysis to provide intermediates for macromolecule biosynthesis.
Metabolic modulation of cancer: a new frontier with great translational potential.
Michelakis et al., Edmonton, Canada. In J Mol Med (berl), Feb 2015
A number of molecular tools and small molecules targeting metabolic enzymes, including pyruvate kinase, pyruvate dehydrogenase kinase, isocitrate dehydrogenase, and lactate dehydrogenase, have been developed, inhibiting cancer growth in vitro and in vivo in several cancer types.
Modulation of SIRT1-Foxo1 signaling axis by resveratrol: implications in skeletal muscle aging and insulin resistance.
Siu et al., Hong Kong, Hong Kong. In Cell Physiol Biochem, 2014
Phosphorylation of Foxo1 is thought to mitigate the transactivation of pyruvate dehydrogenase lipoamide kinase 4 (PDK4), which is a negative regulator of the glycolytic enzyme pyruvate dehydrogenase (PDH).
Inhibition of cancer cell proliferation by PPARγ is mediated by a metabolic switch that increases reactive oxygen species levels.
Kittler et al., Dallas, United States. In Cell Metab, 2014
The antiproliferative effect of PPARγ activation can be prevented by suppressing pyruvate dehydrogenase kinase 4 (PDK4) or β-oxidation of fatty acids in vitro and in vivo.
Clinical impact of the Warburg effect in gastrointestinal cancer (review).
Baba et al., Kumamoto, Japan. In Int J Oncol, 2014
The aim of this review was to discuss significant molecular insights into clinical impacts of the Warburg effect such as oncogenic alterations and overexpression of transcriptional factors (c-Myc and hypoxia-inducible factor), metabolite transporters (glucose transporters) and glycolytic enzymes (hexokinases 2, pyruvate kinase M2, pyruvate dehydrogenase kinase, isozyme 1, lactate dehydrogenase A).
Increasing Superoxide Production and the Labile Iron Pool in Tumor Cells may Sensitize Them to Extracellular Ascorbate.
Contreras et al., Tijuana, Mexico. In Front Oncol, 2013
Measures which inhibit the constitutive hypoxia-inducible factor-1 (HIF-1) activity in cancers (such as salsalate and mTORC1 inhibitors, or an improvement of tumor oxygenation), or that inhibit the HIF-1-inducible pyruvate dehydrogenase kinase (such as dichloroacetate), can be expected to increase pyruvate oxidation.
A key role for mitochondrial gatekeeper pyruvate dehydrogenase in oncogene-induced senescence.
Peeper et al., Amsterdam, Netherlands. In Nature, 2013
BRAF(V600E)-induced senescence was accompanied by simultaneous suppression of the PDH-inhibitory enzyme pyruvate dehydrogenase kinase 1 (PDK1) and induction of the PDH-activating enzyme pyruvate dehydrogenase phosphatase 2 (PDP2).
Regulation of glycolysis by Pdk functions as a metabolic checkpoint for cell cycle quiescence in hematopoietic stem cells.
Suda et al., Tokyo, Japan. In Cell Stem Cell, 2013

Activating cardiac E2F1 induces up-regulation of pyruvate dehydrogenase kinase 4 in mice on a short term of high fat feeding.
Lopaschuk et al., Edmonton, Canada. In Febs Lett, 2012
Data suggest that up-regulation of cardiac PDK4 by high-fat diet (HFD) occurs in conjunction with time-dependent activation of E2F1 transcription factor (E2F1); HFD may initiate early cardiac metabolic alterations through cyclin D1/E2F1/PDK4 axis.
