Osteoblast‐CD4+ CTL Crosstalk Mediated by SIRT1/DAAM2 Axis Prevents Age‐Related Bone Loss

open access: yesAdvanced Science, EarlyView.
In the osteoblastic niche, SIRT1 activates and recruits CD4+ CTLs by increasing DAAM2 expression via EZH2 deacetylation and boosting the secretion of key chemokines, such as CCL3, CCL5, and CXCL10. Then, CD4+ CTL directly eliminates senescent osteoblasts in an MHC‐II‐dependent way, thereby slowing down the process of bone ageing and effectively ...

Enhanced mitochondrial activity reshapes a gut microbiota profile that delays NASH progression

open access: yesHepatology, EarlyView., 2022
Improved mitochondrial activity, due to the lack of methylation‐controlled J protein (MCJ), creates a specific microbiota signature that when transferred through cecal microbiota transplantation delays NASH progression by restoring the gut‐liver axis and enhancing hepatic fatty acid oxidation.

Cloning, expression and characterization of alcohol dehydrogenases in the silkworm Bombyx mori

open access: yesGenetics and Molecular Biology, 2011
Alcohol dehydrogenases (ADH) are a class of enzymes that catalyze the reversible oxidation of alcohols to corresponding aldehydes or ketones, by using either nicotinamide adenine dinucleotide (NAD) or nicotinamide adenine dinucleotide phosphate (NADP ...

Effect of nicotinamide adenine dinucleotide on the membrane-associated reduced nicotinamide adenine dinucleotide oxidase of Mycobacterium phlei.

open access: yesJournal of Biological Chemistry, 1975
NAD+ had a biphasic effect on the NADH oxidase activity in electron transport particles from Mycobacterium phlei. The oxidase was inhibited competitively by NAD+ at concentrations above 0.05 mM. NAD+ in concentrations from 0.02 to 0.05 mM resulted in maximum stimulation of both NADH oxidation and oxygen uptake with concentrations of substrate both ...

Mesencephalic Astrocyte‐Derived Neurotrophic Factor Binds BAX to Preserve Mitochondrial Homeostasis and Energy Metabolism for Relieving Myocardial Hypertrophy

open access: yesAdvanced Science, EarlyView.
MANF in cardiomyocytes interacts with BAX to impede BAX mitochondrial translocation and cytochrome c release, further stabilizing mitochondrial structure and energy supply to relieve myocardial apoptosis and hypertrophy, which indicates MANF as a novel cardioprotective factor to have a promising clinical application for myocardial hypertrophy ...
