AI Article Synopsis
- * Using bioinformatics and experimental methods, the research found that Naringin enhances the bone-forming ability of stem cells while reducing fat accumulation, showing promise for improving ONFH outcomes.
- * The findings suggest that Naringin's benefits for bone health are linked to its ability to increase miR-26a levels and decrease Ski levels, indicating a potential new treatment strategy for ONFH.
Article Abstract
Background: Osteonecrosis of the femoral head (ONFH) is a common orthopedic disease, which seriously affects the quality of life of patients. Naringin has protective effect on ONFH. In present study, we aimed to investigate the mechanism of Naringin regulating miR-26a in ONFH.
Methods: Two sequencing datasets (GSE89587 for micro-RNA, GSE123568 for mRNA) related to ONFH were obtained from the GEO database for bioinformatics analysis. Bone marrow-derived mesenchymal stem cells (BMSCs) were treated with adipogenic medium (AM) or osteogenic medium (OM), and then treated with 10 μM, 100 μM or 1000 μM Naringin. Gene and protein levels were detected by RT-qPCR and Western blotting. ALP activity and alizarin red staining (ARS) were applied to investigate the osteogenic differentiation of BMSCs. Oil red O staining was performed to test adipogenic differentiation. The content of triglycerides (TG) in BMSCs was detected by TG detection kit. Double luciferase reporter gene measured the interaction between miR-26a and Ski.
Results: Bioinfomatic analyses indicated a significant downregulation of miR-26a and a significant upregulation of Ski in the peripheral blood of patients with ONFH. Naringin significantly promoted the osteogenic differentiation, and increased the ALP activity and ARS. Meanwhile, it decreased the adipogenic differentiation and inhibited TG levels. In addition, miR-26a was downregulated and Ski was increased in AM-treated BMSCs, while miR-26a was upregulated and Ski was decreased in OM-treated BMSCs. Furthermore, miR-26a promoted the osteogenic differentiation and suppressed the adipogenic differentiation in BMSCs. Moreover, Naringin enhanced osteogenic potential in BMSCs was reversed by knockdown of miR-26a or overexpression of Ski.
Conclusion: Naringin could promote osteogenic differentiation of BMSCs via mediation of miR-26a/Ski axis. Thereby, Naringin might be a new agent for ONFH treatment.
