CDK1-mediated phosphorylation of LDHA fuels mitosis through LDHB-dependent lactate oxidation

open access: yesEMBO Reports
While cancer cells overexpress lactate dehydrogenase A (LDHA) to support glycolytic flux and lactate production, the role of LDHB—which preferentially catalyzes lactate oxidation—remains unclear. Here, we demonstrate that LDHB, but not LDHA, is essential

AARS2‐SIRT5‐Driven DLD K445 Lactylation Promotes Cuproptosis Resistance in Glioblastoma Stem Cells

open access: yesAdvanced Science, EarlyView.
Lactylation of DLD at K445 by AARS2 suppresses PDH complex activity and reduces DLAT lipoylation, thereby conferring cuproptosis resistance in glioblastoma stem cells. SIRT5‐mediated delactylation restores PDH function and enhances cuproptosis sensitivity.

Superoxide anion production by adriamycinol from cardiac sarcosomes and by mitochondrial NADH dehydrogenase

open access: yes, 1986
This study investigates the effects of both adriamycin and its 13-hydroxylated metabolite adriamycinol on superoxide anion production from cardiac sarcosomes and by mitochondrial NADH dehydrogenase. Superoxide anion production was determined by using the

L-BOAA induces selective inhibition of brain mitochondrial enzyme, NADH-dehydrogenase

open access: yes, 1993
Lathyrism, a human neurological disorder has been linked to the excessive consumption of a plant toxin, β-oxalylamino-L-alanine (L-BOAA) present in Lathyrus sativus.

H4K12 Lactylation Regulates NDUFS7 to Drive Microglia Reverse Electron Transport in Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
Lactate accumulation after SCI promotes H4K12la lactylation, which upregulates NDUFS7, triggering mitochondrial RET and ROS, enforcing pro‐inflammatory microglial polarization. MM@mPTC, a biomimetic nanotherapeutic, degrades LDHA in activated microglia, reducing H4K12la lactylation and blocking RET, thus curbing ROS, fostering a reparative phenotype ...

Flavoprotein-mediated tellurite reduction: structural basis and applications to the synthesis of tellurium-containing nanostructures

open access: yesFrontiers in Microbiology, 2016
The tellurium oxyanion tellurite (TeO32-) is extremely harmful for most organisms. It has been suggested that a potential bacterial tellurite resistance mechanism would consist of an enzymatic, NAD(P)H-dependent, reduction to the less toxic form ...

NADH Electrochemical Sensor Coupled with Dehydrogenase Enzymes

open access: yesAnalytical Letters, 1992
Abstract A graphite electrode assembled in a flow cell has shown to be a good detector for NADH. Current is linearly dependent on concentration in the range 10−7 -10−3 M without any mediator at the potential applied of 300 mV vs Ag/AgCl. Lactate and alcohol dehydrogenases were immobilized near to the electrode surface or in a reactor to obtain an NADH ...

Metabolic Signatures for Liver Cancer Diagnosis and Mechanistic Insights: A Large‐Scale, Multicenter Study

open access: yesAdvanced Science, EarlyView.
A large‐scale multicenter serum metabolomics study (13 centers, n = 2,149) identified a 9‐metabolite + AFP diagnostic signature for liver cancer (AUC = 0.93). Among the signature, nicotinamide (NAM) was validated as an oncometabolite: NAM enhances NAD+ synthesis, activating SIRT1 to deacetylate and stabilize HIF1α, thereby driving glycolysis, MAPK ...

Enzyme-dependent fluorescence recovery of NADH after photobleaching to assess dehydrogenase activity of isolated perfused hearts. [PDF]

open access: yes, 2017
Reduction of NAD(+) by dehydrogenase enzymes to form NADH is a key component of cellular metabolism. In cellular preparations and isolated mitochondria suspensions, enzyme-dependent fluorescence recovery after photobleaching (ED-FRAP) of NADH has been ...
