Regulation of Cardiac-Specific Proteins Expression by Moderate-Intensity Aerobic Exercise Training in Mice With Myocardial Infarction Induced Heart Failure Using MS-Based Proteomics

Frontiers in Cardiovascular Medicine, 2021
This study aims to systematically reveal the changes in protein levels induced by regular exercise in mice with ischemic-induced heart failure (HF). Aerobic exercise training for the ischemic-induced HF mice lasted for 4 weeks and then we used the liquid

Pyruvate dehydrogenase E1α deficiency in a family : Different clinical presentation in two siblings [PDF]

, 1998
The pyruvate dehydrogenase (PDH) complex (PDHc) is responsible for the irreversible conversion of pyruvate to acetyl-CoA. PDHc is a multienzyme complex consisting of three catalytic subunits, pyruvate decarboxylase (E1), dihydrolipoamideacetyltransferase

Scanning mutagenesis of the amino acid sequences flanking phosphorylation site 1 of the mitochondrial pyruvate dehydrogenase complex

Frontiers in Plant Science, 2012
The mitochondrial pyruvate dehydrogenase complex is regulated by reversible seryl-phosphorylation of the E1α subunit by a dedicated, intrinsic kinase. The phospho-complex is reactivated when dephosphorylated by an intrinsic PP2C-type protein phosphatase.

Monitoring phosphorylation of the pyruvate dehydrogenase complex [PDF]

Analytical Biochemistry, 2009
The pyruvate dehydrogenase multienzyme complex (PDC) is a key regulatory point in cellular metabolism linking glycolysis to the citric acid cycle and lipogenesis. Reversible phosphorylation of the pyruvate dehydrogenase enzyme is a critical regulatory mechanism and an important point for monitoring metabolic activity.

In vivo metabolic imaging of Traumatic Brain Injury. [PDF]

, 2017
Complex alterations in cerebral energetic metabolism arise after traumatic brain injury (TBI). To date, methods allowing for metabolic evaluation are highly invasive, limiting our understanding of metabolic impairments associated with TBI pathogenesis ...

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

Rg3 regulates myocardial pyruvate metabolism via P300-mediated dihydrolipoamide dehydrogenase 2-hydroxyisobutyrylation in TAC-induced cardiac hypertrophy

Cell Death and Disease, 2022
The failing heart is characterized by an increase in glucose uptake and glycolytic rates that is not accompanied by a concomitant increase in glucose oxidation.

Understanding Protein-Complex Assembly through Grand Canonical Maximum Entropy Modeling [PDF]

Phys. Rev. Research 3, 033220 (2021), 2021
Inside a cell, heterotypic proteins assemble in inhomogeneous, crowded systems where the abundance of these proteins vary with cell types. While some protein complexes form putative structures that can be visualized with imaging, there are far more protein complexes that are yet to be solved because of their dynamic associations with one another.

Lacticacidaemia due to pyruvate dehydrogenase deficiency, with evidence of protein polymorphism in the α-subunit of the enzyme [PDF]

, 1986
In three infants with neonatal lacticacidaemia, a deficiency in the E 1 (pyruvate dehydrogenase) component of the pyruvate dehydrogenase complex was demonstrated in skin fibroblast cultures. Residual activites of the pyruvate dehydrogenase complex in the

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

J Theor Biol 240: 464-474 (2006), 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 erythroleukemia cells. MAP kinase pathway activation alters the expression of metabolic enzymes in K562 cells.
