A role for reversible phosphorylation in regulation of mitochondrial proteins has been neglected for a long time. Particularly, the import machineries that mediate influx of more than 1000 different precursor proteins into the organelle were considered as predominantly constitutively...

Oxidative phosphorylation enhances the leukemogenic capacity and resistance to chemotherapy of B cell acute lymphoblastic leukemia.

How metabolic status controls the fates of different types of leukemia cells remains elusive. Using a SoNar-transgenic mouse line, we demonstrated that B cell acute lymphoblastic leukemia (B-ALL) cells had a preference in using oxidative phosphorylation. B-ALL cells with...

Hsp40 Affinity to Identify Proteins Destabilized by Cellular Toxicant Exposure.

Analytical chemistry

Quanrud GM, Montoya MR, Mei L, Awad MR, Genereux JC.
PMID: 34874156
Anal Chem. 2021 Dec 07; doi: 10.1021/acs.analchem.1c04230. Epub 2021 Dec 07.

Environmental toxins and toxicants can damage proteins and threaten cellular proteostasis. Most current methodologies to identify misfolded proteins in cells survey the entire proteome for sites of changed reactivity. We describe and apply a quantitative proteomics methodology to identify...

BACKGROUND: Dihydrolipoamide dehydrogenase deficiency (DLDD) is a rare metabolic disorder inherited in an autosomal recessive manner. This heterogeneous disease has a variable clinical presentation, onset, and biochemical markers.MATERIALS AND METHODS: We retrospectively reviewed the clinical and molecular diagnosis of...

Front Nutr. 2021 Dec 14;8:783164. doi: 10.3389/fnut.2021.783164. eCollection 2021.

Anaerobic glycolysis is the process by which glucose is broken down into pyruvate and lactate and is the primary metabolic pathway in sepsis. The pyruvate dehydrogenase complex (PDHC) is a multienzyme complex that serves as a critical hub in...

Dihydrolipoamide dehydrogenase (DLDH) is a mitochondrial enzyme that comprises an essential component of the pyruvate dehydrogenase complex. Lines of evidence have shown that many dehydrogenases possess unrelated actions known as moonlightings in addition to their oxidoreductase activity. As part...
