NAD+ precursors including NMN and nicotinamide riboside
Aging is accompanied by the progressive deterioration of circadian clock function, characterized by reduced amplitude, increased period variability, and impaired metabolic coupling. Declining intracellular nicotinamide adenine dinucleotide (NAD+) levels and SIRT1 activity have been implicated …
Liver aging involves progressive functional decline and increased susceptibility to metabolic diseases. Emerging evidence supports the view that some aspects of liver aging reflect partially reversible disruption of epigenetic and circadian regulatory programs, rather than …
The goal of developing interventions to slow ageing is not only lifespan extension but more importantly to increase healthspan, the period of life spent in active good health. Nutritional interventions have emerged as a potential …
BACKGROUND: Preadipocyte commitment to the adipogenic lineage declines markedly with advancing age, while triglyceride accumulation in hypertrophied existing adipocytes persists or expands. This creates a dissociation between adipogenic capacity and lipid-buffering demand, progressively weakening depot …
Mitochondria play central roles in cellular metabolism and in key processes such as inflammation, stress response, cell death and signalling. Mitochondrial quality control (MQC) mechanisms continuously monitor organelle integrity and function, and repair or eliminate …
The d emographic shift toward an older population is accelerating the prevalence of age-related diseases. Precision geromedicine represents a paradigm shift in targeting the biological processes of ageing to optimise health and healthspan, which likely …
Stem cell fate decisions-whether to self-renew, differentiate, or senesce-are inextricably linked to the metabolic identity and quality-control status of mitochondria. The ubiquitin-proteasome system and selective autophagy pathways assemble into an integrated surveillance network at the …
This review examines NAD+—a crucial molecule for cellular energy and stress response—as a potential therapeutic target for age-related ovarian decline and disorders like polycystic ovary syndrome. The authors conclude that while NAD+ deficiency appears central …
Researchers found that 3,5-dicaffeoylquinic acid (3,5-diCQA), a compound from plants, delayed aging and improved stress resistance in worms and human cells by activating a well-known cellular defense pathway called SKN-1/Nrf2. The compound appears to work …
Researchers used computer simulations to map how a NAD+ analog activates SIR2, an enzyme linked to aging, by triggering a cascade of conformational changes that act like an internal relay system. They identified a previously …
Rhododendron pachypodum flowers are traditionally consumed by ethnic minorities in Yunnan as seasonal edible flowers, yet their bioactive iridoid constituents and associated biological activities remain underexplored. This study characterized the iridoid constituents and evaluated in …
Different types of dietary restriction (DR) have been practiced by humans for religious and medical purposes for millennia, but only during the past three decades has the scientific study of DR at cellular and molecular …
Pseudomonas aeruginosa is a priority pathogen in chronic and multidrug-resistant infections, yet therapeutic phages targeting this organism often exhibit variable and unpredictable efficacy. A mechanistic understanding of the genomic determinants governing phage-host interactions is therefore …
Disruption of the circadian clock as well as reduced NAD+ levels are both hallmarks of aging. While circadian rhythms and NAD+ metabolism have been linked in heart disease, their relationship during cardiac aging is less …
Researchers used lab-grown cells to show that mitochondrial DNA variants affecting energy production influence telomere length by controlling reactive oxygen species and NAD levels. This suggests that inherited mitochondrial traits may influence how quickly our …
Researchers analyzed blood chemistry in 213 people over 100 years old and found they have distinctly different metabolic profiles—especially higher bile acids and lower inflammatory markers—compared to younger controls. By identifying these metabolic signatures, they …
This review argues that combining topical skin treatments (retinoids, peptides, antioxidants) with internal supplements (NAD+ precursors, collagen peptides, polyphenols) can target multiple aging mechanisms simultaneously. While conceptually sound, the paper is a narrative review without …
Researchers genetically modified fruit flies to increase a molecule called NAD+ specifically in their mitochondria (cellular power plants), and found this extended their lifespan and reversed Alzheimer's-like symptoms. This suggests that the NAD+/NADH balance is …
Researchers isolated a fructan sugar compound (PKP-1b) from a traditional Chinese medicinal plant and found it extended lifespan and reduced aging signs in C. elegans and mice by dampening insulin/IGF-1 signaling—a well-known aging pathway. While …
This review examines how NAD+ and a protein called SIRT3 control mitochondrial health in diabetic kidney disease, showing promising preclinical results but noting a critical gap: almost no human clinical evidence yet. If confirmed in …
