A novel long noncoding RNA PGC1β-OT1 regulates adipocyte and osteoblast differentiation through antagonizing miR-148a-3p.

ABSTRACT: Long noncoding RNAs (LncRNAs) have been implicated in the regulation of adipocyte and osteoblast differentiation. However, the functional contributions of LncRNAs to adipocyte or osteoblast differentiation remain largely unexplored. In the current study we have identified a novel LncRNA named peroxisome proliferator-activated receptor γ coactivator-1β-OT1 (PGC1β-OT1). The expression levels of PGC1β-OT1 were altered during adipogenic and osteogenic differentiation from progenitor cells. 5'- and 3'-rapid amplification of cDNA ends (RACE) revealed that PGC1β-OT1 is 1759 nt in full length. Overexpression of PGC1β-OT1 in progenitor cells inhibited adipogenic differentiation, whereas silencing of endogenous PGC1β-OT1 induced adipogenic differentiation. By contrast, overexpression of PGC1β-OT1 in
