LncRNA SNHG14 Delivered by Bone Marrow Mesenchymal Stem Cells‐Secreted Exosomes Regulates Osteogenesis and Adipogenesis in Osteoporosis by Mediating the miR‐27a‐3p/LMNB1 Axis
ABSTRACT The purpose of this study was to investigate the role of LncRNA SNHG14 delivered by bone marrow mesenchymal stem cells‐secreted exosomes (BMSC‐Exos) in osteoporosis (OP). BMSCs and BMSCs‐Exos were isolated and identified. BMSCs were transfected, from which BMSCs‐Exos were collected. The tre...

| Summary: | ABSTRACT The purpose of this study was to investigate the role of LncRNA SNHG14 delivered by bone marrow mesenchymal stem cells‐secreted exosomes (BMSC‐Exos) in osteoporosis (OP). BMSCs and BMSCs‐Exos were isolated and identified. BMSCs were transfected, from which BMSCs‐Exos were collected. The treated BMSCs‐Exos were co‐cultured with BMSCs. After osteogenic induction of BMSCs, the calcification was analyzed by alizarin red S staining. After adipogenic induction of BMSCs, lipid droplets were detected by oil red O staining. Glycerol‐3‐phosphate dehydrogenase activity was measured in BMSCs. OVX mouse models were established and treated with BMSC‐EXOs. HE staining and IHC staining were performed on the femurs of mice. The interaction between SNHG14, miR‐27a‐3p, and LMNB1 was evaluated by luciferase reporter gene assay and RIP assay. Gene levels were assessed using RT‐qPCR and Western blot, respectively. BMSC‐Exos promoted osteogenic‐adipogenic balance of BMSCs. SNHG14 enhanced the promoting effect of BMSCs‐Exos on the balance of osteogenesis and adipogenesis of BMSCs. SNHG14 directly bound miR‐27a‐3p. SNHG1 mediated osteogenic‐adipogenic balance in BMSCs via miR‐27a‐3p. LMNB1 was a target gene of miR‐27a‐3p. LMNB1 was involved in the process of SNHG14 regulating osteogenic‐adipogenic balance in BMSCs. SNHG14 overexpression promoted bone formation and alleviated OP in vivo. SNHG14 delivered by BMSCs‐Exos regulates osteogenesis and adipogenesis in OP by mediating the miR‐27a‐3p/LMNB1 axis. |
