Tissue-specific effects of bacterial PncA overexpression on NAD+ metabolism and aging in mice: implications for tissue-specific aging interventions

open access: yesFrontiers in Aging
BackgroundAs a critical molecule in biological systems, nicotinamide adenine dinucleotide (NAD+) influences the aging of mammals. Therefore, regulation of NAD+ synthesis and degradation may slow aging and mitigate related diseases.ResultsThis study ...

Illuminating point‐of‐care diagnostics with aggregation‐induced emission biosensors

open access: yesFlexMat, EarlyView.
This review highlights the application of aggregation‐induced emission luminogens (AIEgens) in point‐of‐care (POC) diagnostics for disease biomarker detection. It systematically examines a range of biosensing platforms, including lateral flow immunoassays, microfluidic chips, and electrochemiluminescence sensors, alongside their utility in detecting ...

Targeting nicotinamide adenine dinucleotide biosynthesis to improve metabolism

open access: yes
Nicotinamide adenine dinucleotide (NAD) is a cellular metabolite that regulates many biological processes. NAD levels decline with age and also in obesity and interventions that increase NAD levels produce favourable metabolic effects.

Safety and efficacy of long-term nicotinamide mononucleotide supplementation on metabolism, sleep, and nicotinamide adenine dinucleotide biosynthesis in healthy, middle-aged Japanese men

open access: yesEndocrine Journal
Obesity and aging are major risk factors for several life-threatening diseases. Accumulating evidence from both rodents and humans suggests that the levels of nicotinamide adenine dinucleotide (NAD+), a regulator of many biological processes, declines in

Crosstalk Between Parkinson's Disease and Colorectal Cancer: Genetic Mechanisms, Gut Microbiota, and Therapeutic Insights

open access: yesHealth Care Science, EarlyView.
This review elucidates the crosstalk between Parkinson's disease and colorectal cancer, driven by shared genetics (PRKN, PINK1, DJ‐1) involving oxidative stress, cell cycle regulation, and inflammation. It identifies the gut microbiota—via functional amyloids and short‐chain fatty acids (SCFAs)—as a mechanistic bridge, offering insights for dual ...

Nicotinamide Adenine Dinucleotide: The Redox Sensor in Aging-Related Disorders

open access: yes
Significance: Nicotinamide adenine dinucleotide (NADH) represents the reduced form of NAD+, and together they constitute the two forms of the nicotinamide adenine dinucleotide whose balance is named as the NAD+/NADH ratio.

Characterisation of the flavin adenine dinucleotide binding region in Myxococcus xanthus protoporphyrinogen oxidase [PDF]

open access: yes, 2011
This dissertation focuses on protoporphyrinogen oxidase (PPOX), the penultimate enzyme in the haem biosynthetic pathway. Partial defects in PPOX result in variegate porphyria, an autosomal dominant disorder.

Interpretation of Key Updates in the 36th Edition of Clinical and Laboratory Standards Institute M100 Standard

open access: yesiLABMED, EarlyView.
ABSTRACT The Clinical and Laboratory Standards Institute M100 document serves as a cornerstone standard for clinical microbiology laboratories in China. Maintaining the scientific rigor of its predecessors, the 36th edition incorporates updated epidemiological cutoff values, pharmacokinetic/pharmacodynamic data, and clinical efficacy evidence to revise

Soil‐derived, gut‐dominant generalist bacteria shape the fitness of folivorous larvae

open access: yesiMeta, EarlyView.
Whether Lepidoptera harbor a conserved core gut microbiome has long remained contentious. Through large‐scale microbiome profiling of folivorous larvae, their host plants, and associated soils across three climatically distinct regions of China, we identify two soil‐derived generalist bacteria, Ralstonia insidiosa and Delftia sp., that colonize 97.92 ...
