- W4238601885 abstract "Abstract Background: Periodontitis is a chronic inflammatory disease inducing the absorption of alveolar bone and leading to tooth loss. Human amnion-derived mesenchymal stem cells (HAMSCs) have been studied as a potential strategy for inflammatory processes. Here, we explored the role of long non-coding RNA (LncRNA) antisense non-coding RNA in the INK4 locus (ANRIL) in HAMSCs-droved osteogenesis in lipopolysaccharide (LPS)-induced human bone marrow mesenchymal stem cells (HBMSCs). Methods: Cells were incubated with coculture system. Reactive oxygen species (ROS) level and superoxide dismutase (SOD) activity were used to detect oxidative stress level. Flow cytometry was performed to determine the cell proliferation. The Alkaline phosphatase (ALP) and Alizarin red assay, cell transfection and rat mandibular defect model were used to evaluate the osteogenic differentiation. Quantitative real-time reverse transcription polymerase chain reaction (RT-PCR), Western blot, dual-luciferase reporter assay and immunofluorescence Staining were used to evaluate the molecular mechanisms. Results: Here, we discovered that HAMSCs promoted osteogenesis of LPS-induced HBMSCs, while ANRIL level in HBMSCs was decreased during coculturing. ANRIL had no significant influence on the proliferation of LPS-induced HBMSCs, while its overexpression inhibited the HAMSCs-droved osteogenesis in vivo and in vitro ; whereas its knockdown reversed these effects. Mechanistically, we found that downregulating ANRIL led to overexpression of microRNA-125a (miR-125a), and further contributed to the competitively bounding of miR-125a and Adenomatous polyposis coli (APC), thus significantly activating the Wnt/β-catenin pathway. Conclusions: Our study indicates that HAMSCs promote osteogenic differentiation of LPS-induced HBMSCs via ANRIL/miR-125a/APC axis, and offer a novel approach for periodontitis therapy." @default.
