| Study Title | The role of gut microbiota in muscle mitochondria function, colon health, and sarcopenia: from clinical to bench |
| Study Summary | To further investigate if metabolites produced by probiotics could directly improve muscle growth, an in-vitro study was performed by utilizing C2C12 myoblasts and myotubes, as well as probiotic supernatant. The supernatant of probiotics was collected and LC-MS analysis was performed. |

| Project Title: | From clinical to benchside: Lacticaseibacillus and Faecalibacterium are positively associated with muscle health and alleviate age-related muscle disorder |
| Project Summary: | Sarcopenia is an age-related muscle disorder that increases the risk of adverse clinical outcomes, but its pathogenesis is unclear and treatments are limited. Increasing evidence shows that gut microbiota is potentially associated with sarcopenia. 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. Metagenomic and metabolomic analyses showed that people with sarcopenia had different microbial composition and metabolites, and that fecal purine could accurately identify sarcopenia. After FMT, mice receiving microbes from people with sarcopenia displayed lower muscle mass and strength. Correlation analysis revealed Lacticaseibacillus rhamnosus (LR) and Faecalibacterium prausnitzii (FP) were positively related to muscle health in old people. Both probiotic LR, FP and their combination enhanced muscle mass, function, and fiber type proportion of aged mice. Transcriptomics showed that genes related to tricarboxylic acid cycle were enriched after treatment. Mitochondria density, muscle ATP content, NAD+/NADH, proteins related to mitochondrial dynamics and biogenesis were improved by both probiotics. In in-vitro studies, probiotic-conditional medium (PCM) containing FP supernatant or the combination of FP and LR supernatants enhanced proliferation of C2C12 myoblasts, whilst LR PCM alone did not. The mechanisms of LR may be related to colon health improvement. Results showed gut microbiota dysbiosis is one of pathogenic factors of sarcopenia, and muscle-related probiotics could alleviate age-related muscle disorders. Further clinical translation is warranted. |

Collection:
| Collection ID: | CO003104 |
| Collection Summary: | The Lacticaseibacillus rhamnosus ATCC 53103 was cultured on MRS Agar (Sigma, USA), and a single colony of LR was cultured in DeMan-Rogosa-Sharpe (MRS, Sigma) broth to obtain 108 colony forming unit (CFU)/mL in the anaerobic chamber (Bugbox Plus UM-017, Baker). After centrifugating at 1600g for 10 min at 4 ℃ and discarding supernatant, the pellet was resuspended in sterile water, centrifuged again, and the supernatant was discarded. The pellet was resuspended in 1 mL to obtain 1010 CFU/mL. The CFU was enumerated by culturing 10 μL of the aliquot by serial dilution method in Blood agar. The Faecalibacterium prausnitzii ATCC27768 was cultured on freshly prepared pre-reduced YBHA media. After 48h incubation at 37 ℃ in the anaerobic chamber, a single colony from the YBHA plate was cultured in the YBHI media to obtain 108/mL. The dilution and enumeration procedures were as above. |

Treatment:
| Treatment ID: | TR003120 |
| Treatment Summary: | The medium and supernatant of probiotics (LR and FP) were obtained from three separate preparations (n = 3 per group). 100 μL of sample was transferred to an EP tube. After the addition of 400 μL of extract solution (methanol: acetonitrile= 1: 1, containing isotopically-labelled internal standard mixture), the samples were vortexed for 30 s, sonicated for 10 min in ice-water bath, and incubated for 1 h at -40 ℃ to precipitate proteins. Then the sample was centrifuged at 12000 rpm(RCF=13800(×g),R= 8.6cm) for 15 min at 4 ℃. The resulting supernatant was transferred to a fresh glass vial for analysis. The quality control (QC) sample was prepared by mixing an equal aliquot of the supernatants from all of the samples. |
