Gut microbial metabolite 7-ketodeoxycholic acid ameliorates diabetic sarcopenia by suppressing NLRP1-mediated ferroptosis in myotubes

To identify the potential metabolites that may play a role in the relationship between gut metabolites and diabetic sarcopenia, we used untargeted and targeted metabolomics analysis was performed by gas chromatography mass spectrometry (GC-MS) to identify the fecal metabolites.
