Background: Gut microbiota dysbiosis is a critical contributor to the pathogenesis and progression of inflammatory bowel disease (IBD). Darutigenol (DL), a natural compound has demonstrated significant anti-inflammatory activity, but its low oral bioavailability limits its application. However, t...
In natural environments, photosynthetic organisms adjust their metabolism to cope with the fluctuating availability of combined nitrogen sources, a growth-limiting factor. For acclimation, the dynamic degradation/synthesis of tetrapyrrolic pigments, as well as of the amino acid arginine, is ...
Aortic disease poses a significant mortality risk in adults, yet many of its underlying factors remain undiscovered. In this study, we identify mitochondrial NAD⁺ deficiency as a causal factor. Metabolomics analysis of 73 surgical aortic specimens revealed impaired NAD⁺ salvage and mitochondrial ...
