Deoxycholic acid at 20 mg/kg mitigates ovariectomy-induced trabecular and cortical bone loss in mice by inhibiting osteoclastogenesis and enhancing osteoblastogenesis.
- Why it matters: Postmenopausal osteoporosis is linked to gut microbiota dysbiosis and altered microbial metabolites, including reduced secondary bile acid availability, but DCA’s bone effects are underexplored.
- What they did: In ovariectomised mice for 45 days, DCA was tested alongside serum cytokine profiling, osteoclast/osteoblast assays, metabolomics, and secondary 16S rRNA sequencing analysis; human PBMCs and PMO women’s BMSCs were used for mechanistic readouts.
- The result: DCA improved bone microarchitecture, shifted circulating osteoclastogenic and osteoblastogenic factors, suppressed osteoclast differentiation and osteoclast-related gene expression in human PBMCs, promoted osteogenic differentiation and mineralization in PMO BMSCs, and enhanced nascent calcium deposition and fracture healing.
