The role of gut microbiota in muscle mitochondria function, colon health, and sarcopenia: from clinical to bench

To investigate its role in sarcopenia, we (i) compared gut microbiota and metabolite composition between older persons with and without sarcopenia, (ii) performed fecal microbiota transplantation (FMT) from human donors to antibiotic-treated mice, and (iii) identified two specific probiotics for treatment of sarcopenia in aged mice. The results showed that older persons with sarcopenia had distinctive gut microbiota characteristics, and muscle-related probiotics enhanced muscle status of aged mice through mitochondria improvement.
