Probiotics and prebiotics for preventing and alleviating the degenerative changes associated with aging have received extensive attention. In the present work,() 69-2 with the highest antioxidant capacity combined with galacto-oligosaccharide (GOS) was used in aging model mice to evaluate the effect on aging and the regulation of gut microbiota. The combination of69-2 and GOS supplementation could significantly (0.05) improve liver function, antioxidant capacity, and inflammation accompanied by regulating the gut microbiota, increasing the short chain fatty acid (SCFA) levels, and activating the hepatic AMPK/SIRT1 regulatory pathway. The results showed that69-2 and GOS could activate the hepatic AMPK/SIRT1 signaling pathway by regulating the gut microbiota and metabolites through the liver-gut axis to restore hepatic antioxidant activity to alleviate aging. The study provided a new insight for targeting the gut microbiota to relieve aging through the gut-liver axis.
