Macrophage‐derived MLKL in alcohol‐associated liver disease: Regulation of phagocytosis

Hepatology, EarlyView., 2022
EtOH causes leaky gut allowing bacteria and PAMPs into the liver, resulting in hepatic inflammation and injury. We demonstrate that LPS induces STAT1‐mediated expression and phosphorylation of MLKL in macrophages and identify a novel function that myeloid MLKL translocates to phagosomes and lysosomes and regulates phagocytosis, which contributes to the

NAD+ Repletion Rescues Female Fertility during Reproductive Aging

Cell Reports, 2020
Summary: Reproductive aging in female mammals is an irreversible process associated with declining oocyte quality, which is the rate-limiting factor to fertility. Here, we show that this loss of oocyte quality with age accompanies declining levels of the

Ruling out pyridine dinucleotides as true TRPM2 channel activators reveals novel direct agonist ADP-ribose-2'-phosphate [PDF]

, 2015
Transient receptor potential melastatin 2 (TRPM2), a Ca(2+)-permeable cation channel implicated in postischemic neuronal cell death, leukocyte activation, and insulin secretion, is activated by intracellular ADP ribose (ADPR).

Melatonin Modulates Glucose Metabolism Reprogramming via Targeting G6PD to Alleviate Lead‐Induced Hepatocytes Pyroptosis in Common Carp (Cyprinus carpio L.)

Advanced Science, EarlyView.
This study reveals that Lead reprograms glucose metabolism to enhance H3K18la, driving DRP1‐dependent mitochondrial DNA leakage and cGAS‐STING‐mediated pyroptosis. Melatonin targets G6PD to suppress glycolysis‐driven H3K18la and restore mitochondrial homeostasis, thereby alleviating Lead‐induced liver injury in common carp through disruption of the ...

Essential lipid autacoids rewire mitochondrial energy efficiency in metabolic dysfunction‐associated fatty liver disease

Hepatology, EarlyView., 2022
Increased liver content of DHA‐derived small lipid autacoids (i.e resolvin D1 and maresin 1) associates with enhanced mitochondrial oxidative phosphorylation, fatty acid β‐oxidation and bioenergetic metabolic flux. These features provide hepatic protection from steatotic, pro‐inflammatory and fibrogenic insults.

Nicotinamide adenine dinucleotide suppresses epileptogenesis at an early stage

Scientific Reports, 2017
The pathophysiologic mechanisms of epileptogenesis are poorly understood, and no effective therapy exists for suppressing epileptogenesis. Numerous reports have shown that nicotinamide adenine dinucleotide (NAD+) has neuroprotective effects, suggesting ...

Insight into an Oxidative DNA-Cleaving DNAzyme: Multiple Cofactors, the Catalytic Core Map and a Highly Efficient Variant

iScience, 2020
Summary: An oxidative DNA-cleaving DNAzyme (PL) employs a double-cofactor model “X/Cu2+” for catalysis. Herein, we verified that reduced nicotinamide adenine dinucleotide (NADH), flavin mononucleotide, cysteine, dithiothreitol, catechol, resorcinol ...

Identification of LDH-A as a therapeutic target for cancer cell killing via (i) p53/NAD(H)-dependent and (ii) p53 independent pathways [PDF]

, 2014
Most cancer cells use aerobic glycolysis to fuel their growth. The enzyme lactate dehydrogenase-A (LDH-A) is key to cancer’s glycolytic phenotype, catalysing the regeneration of nicotinamide adenine dinucleotide (NAD þ ) from reduced nicotinamide adenine

Intramitochondrial Localization of the Nicotinamide Adenine Dinucleotide- and Nicotinamide Adenine Dinucleotide Phosphate-dependent Xylitol Dehydrogenases

Journal of Biological Chemistry, 1968
Abstract The two mitochondrial xylitol dehydrogenases of guinea pig liver have been studied with a view to determining their intramitochondrial locations. By procedures involving swelling, shrinking, and sonic oscillation of the particles, followed by centrifugation in a discontinuous sucrose gradient, preparations representing solubilized enzymes ...
