研究问题

To investigate the effects of moxibustion (MOX) on bone loss and osteogenic differentiation in ovariectomized (OVX) rats and determine whether these effects are mediated by mitophagy through bone marrow mesenchymal stem cells (BMSCs)-derived exosomal miR-27a-3p.

方法

The study was conducted in three stages.

核心结论

In stage 1, sham-operated (SO), OVX, and OVX + MOX rats were evaluated by micro-computed tomography (micro-CT) to assess bone mass and by Alizarin Red S (ARS) staining to evaluate osteogenic differentiation.;Autophagy-related markers were also examined, and mitochondrial-lysosomal colocalization was assessed by immunofluorescence.;In stage 2, the mitophagy inhibitor Mdivi-1 was administered to OVX + MOX rats to determine the contribution of mitophagy to the effects of MOX.;Sequencing analysis and TargetScan prediction identified a potential regulatory relationship between miR-27a-3p and the mitophagy-related gene PINK1, which was subsequently validated using a dual-luciferase reporter assay. ‖ 结论:These effects may be mediated, at least in part, by activation of mitophagy through the BMSCs-associated miR-27a-3p/PINK1 axis, providing a potential mechanistic basis for the therapeutic effects of MOX in OP.
