Sirtuins are a family of NAD(+)-dependent protein deacetylases/deacylases that dynamically regulate transcription, metabolism, and cellular stress response. Their general positive link with improved health span in mammals, potential regulation of pathways mediated by caloric restriction, and growing links to human disease have spurred interest in therapeutics that target their functions. Here, we review the current understanding of the chemistry of catalysis, biological targets, and endogenous regulation of sirtuin activity. We discuss recent efforts to generate small-molecule regulators of sirtuin activity.

Endothelial-mesenchymal transition (EnMT) is the transversion of endothelial cells to mesenchymal cells under certain physiological or pathological conditions. When EnMT occurs in the corneal endothelium, corneal endothelial cells (CECs) lose their normal function and thus cannot maintain corneal clarity. Studies have shown that the mechanism of EnMT in CECs involves the transforming growth factor-β (TGF-β) signaling pathway, and one of the important inhibitors of the TGF-β/Smad2/3 pathway is sirtuin-1 (SIRT1).

Background: Multiple myeloma, a malignancy of plasma cells, often involves the disruption of vitamin D metabolism. Vitamin D, acting through its receptor (VDR), affects transcription factors like FOXO and sirtuins, which regulate cellular processes. The impact of physical activity on these markers in multiple myeloma patients is unclear.

Background: Chronic obstructive pulmonary disease (COPD) is a prevalent yet manageable respiratory condition. However, treatments presently used normally have side effects and cannot cure COPD, making it urgent to explore effective medications. The ginsenoside Rg3 (Rg3) has been shown to have anti-inflammatory and anti-tumor properties and can improve COPD.

Resveratrol (RSV), a natural polyphenol, has been suggested to influence glucose and lipid metabolism. However, the underlying molecular mechanism of its action remains largely unknown due to its multiple biological targets and low bioavailability. In this study, we demonstrate that RSV supplementation ameliorates high-fat-diet (HFD)-induced gut microbiota dysbiosis, enhancing the abundance of anti-obesity bacterial strains such as and .

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a prevalent chronic liver disease associated with type 2 diabetes, which doubles the risk of developing this condition. Various flavonoid compounds have a positive effect on lipid metabolism, inflammation, and insulin resistance and can contribute to slowing down the progression of MASLD. In the current study, we investigated the biological effects of Licochalcone D (Lico D), a flavonoid, in a metabolic disease model.
