Abstract:

BACKGROUND: Long non-coding RNAs (lncRNAs) have became the hot topic in current studies and play an important role in the tumorigenesis. However, lncRNAs involved in the osteoblast differentiation remain poorly reported.
OBJECTIVE: To investigate the role of human LncRNAs in osteogenic differentiation of C3H10T1/2 cells induced by bone morphogenetic protein-2 and explore action mechanism.
METHODS: The induction of bone morphogenetic protein-2 was validated by alkaline phosphatase staining and the expression of corresponding genes was detected. The lncRNA expression profile was analyzed using the Arraystar lncRNA array in C3H10T1/2 MSCs undergoing early osteoblast differentiation. The expression with or without bone morphogenetic protein-2 induction was compared with high-flux sequencing, and the down-regulated genes were screened. The effect of lncRNA overexpression on osteogenic differentiation of C3H10T1/2 cells induced by bone morphogenetic protein-2 was observed.
RESULTS AND CONCLUSION: The bone morphogenetic protein-2 induced C3H10T1/2 cells led to increased alkaline phosphatase activity. After 72 hours of bone morphogenetic protein-2 induction, alkaline phosphatase,
Id1,osteocalcin, Runx2, sp7 expression were increased (P < 0.05). There were 24 down-regulated lncRNAs identified between bone morphogenetic protein-2 treated and untreated groups, the decrease of expression was 1.5 folds, and among them, only AK035085 contained intron. Compared with control group with no AK03508 expression, over-expression lncRNA AK035085 decreased the expression of alkaline phosphatase, Id1, osteocalcin, Runx2, sp7   (P < 0.05). Experimental findings indicate that bone morphogenetic protein-2 induces osteogenic differentiation of C3H10T1/2 cells and AK035085 inhibits the osteogenic differentiation.
