Abstract

Bone marrow-derived mesenchymal stem cells (BM-MSCs) are the main source of osteoblasts in vivo and are widely used in stem cell therapy. Previously, we analyzed long noncoding RNA (lncRNA) expression profiles during BM-MSC osteogenesis, and further investigation is needed to elucidate how lncRNAs regulate BM-MSC osteogenesis. Herein, we used customized microarrays to determine lncRNA expression profiles in BM-MSCs on days 0 and 10 of osteogenic differentiation. In addition, we identified a novel osteogenesis-associated lncRNA (lncRNA-OG) that is upregulated during this process. Functional assays showed that lncRNA-OG significantly promotes BM-MSC osteogenesis. Mechanistically, lncRNA-OG interacts with heterogeneous nuclear ribonucleoprotein K (hnRNPK) protein to regulate bone morphogenetic protein signaling pathway activation. Surprisingly, hnRNPK positively regulates lncRNA-OG transcriptional activity by promoting H3K27 acetylation of the lncRNA-OG promoter. Therefore, our study revealed a novel lncRNA with a positive function on BM-MSC osteogenic differentiation and proposed a new interaction between hnRNPK and lncRNA.
