Alcoholic liver disease (ALD) is still a global health concern. Long-term alcohol intake alters the gut microbiota diversity and metabolic activity, and causes intestinal barrier dysfunction, leading to the development...
Artemisia selengensis Turcz. (AST), as a common edible and medicinal herb, exerts multiple biological activities including antioxidant, antihyperuricemia, and inhibition of α-glucosidase activities. However, limited information is available about its beneficial effects on high glucose toxicity in Caenorhabditis elegans (C. elegans). In the current study, Artemisia selengensis Turcz. leaf extract (ASTE), rich in caffeoylquinic acids, was found to alleviate high glucose-induced damages in C. elegans by extending the lifespan, increasing the body bending and pharyngeal pumping rates, and by reducing glucose and lipid accumulation and oxidative stress. Further results demonstrated that ASTE extended the lifespan of C. elegans on high glucose diet by inhibiting the insulin/IGF-1 signaling (IIS), and activating SKN-1 and AAK-2 signaling pathways. In conclusion, our findings reveal the direct evidence for the protective effects of ASTE against high glucose toxicity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
