Neohesperidin promotes the osteogenic differentiation of human bone marrow stromal cells by inhibiting the histone modifications of lncRNA SNHG1
Neohesperidin (NH) was reported to regulate osteoclastic differentiation, while LncRNA SNHG1 could inhibit osteogenic differentiation of bone marrow stromal cells (BMSCs). In this study, we aimed to explore whether SNHG1-mediated osteogenic differentiation could be regulated by NH. Osteonecrosis and adjacent tissues, as well as normal bone marrow samples were gathered. BMSCs were isolated from normal bone marrow samples by Ficoll density gradient and identified by flow cytometry. Histopathological changes of tissues were detected by hematoxylin-eosin staining. After the treatment with NH or transfection, cell viability, osteogenic differentiation, and the activity of alkaline phosphatase (ALP) in BMSCs were detected by MTT, alizarin red staining, and microplate method, respectively. The histone modification and expressions of SNHG1 and osteogenic marker genes in tissues or BMSCs were detected by q-PCR and Chromatin Immunoprecipitation (ChIp). SNHG1 was highly expressed in osteonecrosis tissues, and typical signs of empty lacunae appeared in the necrotic tissues zone. NH increased viability and osteogenic differentiation of BMSCs, activity of ALP, and expressions of RUNX2, OCN and ALP. NH decreased both SNHG1 expression and H3K4me3 (activating histone modification) occupancies and increased H3K27me3 (inhibiting histone modification) occupancies of SNHG1. Furthermore, siSNHG1 enhanced osteogenic differentiation of BMSCs and expressions of RUNX2, OCN and ALP, while SNHG1 overexpression did the opposite and reversed the effects of NH on the osteogenic differentiation of BMSCs. In a word, NH promotes the osteogenic differentiation of human BMSCs by inhibiting the histone modifications of lncRNA SNHG1.
