Regulation of pyruvate carboxylase in Rhizobium etli [PDF]

FEMS Microbiology Letters, 2006
Pyruvate carboxylase (PYC) is a biotin-dependent enzyme catalyzing the anaplerotic conversion of pyruvate to oxaloacetate in Rhizobium etli strain CE3. A pyc::Tn5 mutant had severely reduced growth, or failed to grow on sugars, three-carbon organic acids or glycerol, consistent with these substrates being metabolized via pyruvate.

Ubiquitination in cancer: mechanisms and therapeutic opportunities

Cancer Communications, EarlyView.
Abstract Ubiquitination, a key post‐translational modification, plays an essential role in tumor biology by regulating fundamental cellular processes, such as metabolism and cell death. Additionally, it interacts with other post‐translational modifications, which are closely linked to tumorigenesis, tumor progression, the tumor microenvironment, and ...

The citrate cleavage pathway and lipogenesis in rat adipose tissue: replenishment of oxaloacetate

Journal of Lipid Research, 1967
Fatty acid synthesis via the citrate cleavage pathway requires the continual replenishment of oxaloacetate within the mitochondria, probably by carboxylation of pyruvate.Malic enzyme, although present in adipose tissue, is completely localized in the ...

Manganese Neurotoxicity and Familial Disorders of Manganese Transport

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Manganese is the 12th most common element in the Earth's crust and is an essential industrial component. Biologically, this metal plays an important role as a constituent of numerous enzymes. While manganese is required for normal biochemical and physiological processes, manganese excess can lead to significant toxicity, particularly to the ...

Inherited metabolic epilepsies–established diseases, new approaches

Epilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.

Genome‐Wide CRISPR/Cas9 Library Screening Revealed Dietary Restriction of Glutamine in Combination with Inhibition of Pyruvate Metabolism as Effective Liver Cancer Treatment

Advanced Science, 2022
Hepatocellular carcinoma (HCC) is the second most lethal cancer worldwide. Glutamine is an essential, extracellular nutrient which supports HCC growth. Dietary glutamine deficiency may be a potential therapeutic approach for HCC.

Oat Bran Supplementation Improves Glucose Metabolism, Food Addiction, and Gut Microbiota in Rats With High‐Fat Diet‐Induced Obesity

Food Frontiers, EarlyView.
ABSTRACT Oat bran (OB), a byproduct of the oat milling process, is a nutrient‐dense cereal cultivated in cool, dry mountainous regions and is known for its potential health benefits. To explore its obesity‐alleviating effects and the underlying mechanisms, we examined the influence of OB on glucose metabolism, appetite‐regulating hormones, gut ...
