The oncometabolite, D-2-hydroxyglutarate, accumulates in various cancers because of acquired mutations in isocitrate dehydrogenase 1 & 2. Here, we describe a new mechanism for D-2-hydroxyglutarate accumulation in breast cancer.

Escherichia coli isocitrate dehydrogenase is completely inactivated by phosphorylation of a single serine residue per subunit. We have examined the conformations of the active and phosphorylated forms of the enzyme using circular dichroism spectroscopy ...

Bioenergetic Materials for Tissue Regeneration: Modulating Metabolism to Promote Cellular Anabolism
Bioenergetic materials (BEMs) modulate cellular metabolism to promote tissue regeneration. Their principal mechanisms of action include metabolic substrate supplementation, metabolic enzyme modulation, organelle transfer, electrical current regulation, redox homeostasis modulation, and oxygen tension modulation.

Conjugated polymer‐supported bioelectrochemical systems are shown to enhance microbial electrosynthesis by triggering coordinated electrochemical, transcriptional, post‐transcriptional (sRNA), metabolic, and protein‐level responses. Integrated multi‐omics and electrochemical analyses reveal selective physiological remodeling associated with improved ...

Isocitrate dehydrogenase mutations in myeloid malignancies [PDF]
Alterations to genes involved in cellular metabolism and epigenetic regulation are implicated in the pathogenesis of myeloid malignancies. Recurring mutations in isocitrate dehydrogenase (IDH) genes are detected in approximately 20% of adult patients with acute myeloid leukemia (AML) and 5% of adults with myelodysplastic syndromes (MDS).

The oleaginous yeast Lipomyces starkeyi can accumulate intracellular lipids to over 60% of its cell dry mass under a nitrogen-limited condition. We showed that extracellular and intracellular citrate concentrations of L.

A low‐density lipoprotein receptor‐oriented biomimetic nanoplatform couples brain‐tumor delivery with a mechanistically matched regorafenib‐erythrodiol combination. Concurrent disruption of autophagic nutrient salvage and cholesterol homeostasis collapses bioenergetic and signaling support, suppresses glioblastoma stemness, and promotes immunogenic ...

ABSTRACT Background Sinonasal neuroendocrine carcinoma (SNEC) and sinonasal undifferentiated carcinoma (SNUC) are rare aggressive malignancies with no established prognostic markers. Because features of POU2F3+ small cell lung carcinomas have been identified in both tumors, we evaluated immunostaining for POU2F3, a tuft cell transcription factor, and ...

Patient‐Derived Fibroblasts as a Clinically Relevant Model of Kearns–Sayre Syndrome
Objective Kearns–Sayre syndrome (KSS) is characterized by single large‐scale mitochondrial DNA deletions and by severe early‐onset clinical manifestations with neurological involvement. Reliable disease models, as well as validated biomarkers or effective treatments, are lacking.

Mitochondrial Isocitrate Dehydrogenases from Yeast
Abstract A polarographic technique suitable for kinetic studies of either isolated or bound pyridine nucleotide-linked dehydrogenases was used to investigate the isocitrate dehydrogenases of yeast mitochondria. Intact mitochondria were found to contain both triphosphopyridine nucleotide- and diphosphopyridine nucleotide-linked isocitrate dehydrogenases
