    Abstract:
    BACKGROUND: Osteogenic differentiation of human bone marrow-derived mesenchymal stem cells (hBMSCs) is crucial for bone formation and its dysfunction is reported to be linked to osteoporosis (OP). The present study aimed to probe the function of the long non-coding RNA small nucleolar RNA host gene 16 (SNHG16) with respect to modulating the osteogenic differentiation of hBMSCs. METHODS: SNHG16 expression in hBMSCs obtained from OP patients was measured by a quantitative real-time polymerase chain reaction (qRT-PCR). Gain-of-function and loss-of-function models of SNHG16 were established with hBMSCs. The expression of OP-related genes (ALP, OCN and OPN) in hBMSCs was determined by qRT-PCR and western blotting. StarBase, TargetScan7.2, miRDB and PicTar databases were used to predict the binding sites between SNHG16 and miR-485-5p, miR-485-5p and 3'-UTR of bone morphogenetic protein 7 (BMP7), respectively. A dual-luciferase reporter assay was used to determine the regulatory relationships between SNHG16 and miR-485-5p, miR-485-5p and 3'-UTR of BMP7, respectively. RESULTS: SNHG16 was remarkably down-regulated in hBMSCs obtained from patients with OP. Overexpression of SNHG16 promoted the osteogenic differentiation of hBMSCs, whereas knockdown of SNHG16 suppressed it. Mechanistically, miR-485-5p is a target of SNHG16, and miR-485-5p can reverse the function of SNHG16. BMP7 is also identified as a target of miR-485-5p and can be indirectly modulated by SNHG16 in hBMSCs. CONCLUSIONS: SNHG16 promotes the osteogenic differentiation of hBMSCs via regulating the miR-485-5p/BMP7 axis and comprises a prospective therapy target for OP.
