Regulation of pyruvate dehydrogenase complex: Dancing to different drums in cancer. [PDF]
Abstract Mechanisms governing the regulation of pyruvate dehydrogenase complex (PDC) are markedly modified in cancer cells compared to normal cells. PDC activity in normal cells is controlled by the reversible phosphorylation of three serine residues by dedicated kinases and phosphatases.

Protein phosphorylation in yeast mitochondria [PDF]
We describe the identification and submitochondrial localization of four protein kinases and of their target proteins in derepressed yeast mitochondria. The activity of one of the kinases depends on the presence of cyclic AMP (cAMP).

Purification and Characterization of Pyruvate‐Dehydrogenase Phosphatase from Pig‐Heart Muscle [PDF]
Pyruvate‐dehydrogenase phosphatase was extensively purified from pig heart muscle. The molecular weight was determined to be in the range between 92000 and 95000. By dodecylsulfate‐gel electrophoresis there was no indication for a subunit structure of the protein. The phosphatase is dependent on Mg2+ or Mn2+.

Annexin A13 Protects Against Acute Kidney Injury by Inactivating TGF‐β/Smad3 Signaling
ANXA13 is negatively regulated by Smad3 and exerts its protective role in AKI by inactivating TGF‐β/Smad3 signaling and Smad3‐p21 cell cycle arrest pathway through binding to TβRI, inhibiting the interaction between TβRI and TβRII, thereby suppressing TβRI phosporylation.

The metabolic advantage of tumor cells
1- Oncogenes express proteins of "Tyrosine kinase receptor pathways", a receptor family including insulin or IGF-Growth Hormone receptors. Other oncogenes alter the PP2A phosphatase brake over these kinases.

Phosphoenolpyruvate Carboxykinase Is Involved in the Decarboxylation of Aspartate in the Bundle Sheath of Maize [PDF]
We recently showed that maize (Zea mays L.) leaves contain appreciable amounts of phosphoenolpyruvate carboxykinase (PEPCK; R.P. Walker, R.M. Acheson, L.I. Técsi, R.C. Leegood [1997] Aust J Plant Physiol 24: 459–468).

PFOA exposure induces pregnancy loss by promoting glutaminolysis, which further causes ammonia accumulation in macrophages. Cellular ammonia retention results in damage to mitochondria and lysosomes, which leads to cell death eventually. Impaired lysosomes also decrease the secretion of the Cathepsin B (CTSB), and attenuate macrophage infiltration and ...
