A Novel Long Noncoding RNA, Lnc-OAD, Is Required for Bone Morphogenetic Protein 2- (BMP-2-) Induced Osteoblast Differentiation. BIOMED RESEARCH INTERNATIONAL 2021; 2021:6697749. [PMID: 33816629 PMCID: PMC7987440 DOI: 10.1155/2021/6697749] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/02/2020] [Revised: 12/08/2020] [Accepted: 03/03/2021] [Indexed: 01/16/2023]
Abstract
Long noncoding RNAs (lncRNAs) play very important roles in cell differentiation. Our recent study has demonstrated that a novel lncRNA named lnc-OAD modulated 3T3-L1 adipocyte differentiation. In the present study, we examined the roles of lnc-OAD in bone morphogenetic protein 2- (BMP-2-) induced osteoblast differentiation. Lnc-OAD expression was increased during BMP-2-induced osteoblast differentiation in C3H10T1/2 mesenchymal stem cells and MC3T3-E1 preosteoblast cells. Knockdown of lnc-OAD expression by specific siRNA remarkably decreased early osteoblast differentiation. In addition, stable knockdown of lnc-OAD by lentivirus vector also significantly inhibited late osteoblast differentiation and matrix mineralization in vitro. Conversely, stably overexpressed lnc-OAD with lentiviral vector accelerated osteoblast differentiation. Mechanistically, knockdown of lnc-OAD reduced significantly the phosphorylation of AKT and the expression of Osterix induced by BMP-2, while overexpression of lnc-OAD enhanced the phosphorylation of AKT and the expression of Osterix. Taken together, our study suggests that lnc-OAD plays an important role in modulating BMP-2-induced osteoblast differentiation via, at least in part, regulating the AKT-Osterix signaling axis.

Molecules 2019; 24:molecules24132391. [PMID: 31261664 PMCID: PMC6650900 DOI: 10.3390/molecules24132391] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2019] [Revised: 06/23/2019] [Accepted: 06/27/2019] [Indexed: 02/07/2023] Open
Abstract
Obesity is a serious health problem, while the current anti-obesity drugs are not very effective. The Connectivity Map (C-Map), an in-silico drug screening approach based on gene expression profiles, has recently been indicated as a promising strategy for drug repositioning. In this study, we performed mRNA expression profile analysis using microarray technology and identified 435 differentially expressed genes (DEG) during adipogenesis in both C3H10T1/2 and 3T3-L1 cells. Then, DEG signature was uploaded into C-Map, and using pattern-matching methods we discovered that pyrvinium, a classical anthelminthic, is a novel anti-adipogenic differentiation agent. Pyrvinium suppressed adipogenic differentiation in a dose-dependent manner, as evidenced by Oil Red O staining and the mRNA levels of adipogenic markers. Furthermore, we identified that the inhibitory effect of pyrvinium was resulted primarily from the early stage of adipogenesis. Molecular studies showed that pyrvinium downregulated the expression of key transcription factors C/EBPa and PPARγ. The mRNA levels of notch target genes Hes1 and Hey1 were obviously reduced after pyrvinium treatment. Taken together, this study identified many differentially expressed genes involved in adipogenesis and demonstrated for the first time that pyrvinium is a novel anti-adipogenic compound for obesity therapy. Meanwhile, we provided a new strategy to explore potential anti-obesity drugs.

Abstract
Osteoblastic differentiation is a multistep process characterized by osteogenic induction of mesenchymal stem cells, which then differentiate into proliferative pre-osteoblasts that produce copious amounts of extracellular matrix, followed by stiffening of the extracellular matrix, and matrix mineralization by hydroxylapatite deposition. Although these processes have been well characterized biologically, a detailed transcriptional analysis of murine primary calvaria osteoblast differentiation based on RNA sequencing (RNA-seq) analyses has not previously been reported. Here, we used RNA-seq to obtain expression values of 29,148 genes at four time points as murine primary calvaria osteoblasts differentiate in vitro until onset of mineralization was clearly detectable by microscopic inspection. Expression of marker genes confirmed osteogenic differentiation. We explored differential expression of 1386 protein-coding genes using unsupervised clustering and GO analyses. 100 differentially expressed lncRNAs were investigated by co-expression with protein-coding genes that are localized within the same topologically associated domain. Additionally, we monitored expression of 237 genes that are silent or active at distinct time points and compared differential exon usage. Our data represent an in-depth profiling of murine primary calvaria osteoblast differentiation by RNA-seq and contribute to our understanding of genetic regulation of this key process in osteoblast biology.
