Abstract

Objective To explore the differential expression of 14 kinds of long non?--coding RNAs in bone tissues derived from osteogenesis imperfecta patients. Methods RT-qPCR was performed to detect the expression level of 14 Kinds of lncRNAs including ATB, EBIC, HEIH, hLACR1, HOTAIR, PVT1, LET, Loc285194, SRHC, LSINCTS, Nbla10727, Nbla12061, PRNCR1 and UC.388 in bone tissues derive from osteogenesis imperfect (OI) patients who received corrective surgery. Bone tissues from developmental dysplasia of the hip (DDH) were used as control. REST-2009 was performed to analyze the results. Results The expression of PRNCR1 was significantly down-regulated in OI bone tissues. There’s no differential expression was observed in other thirteen lncRNAs, though the expression of HEIH, hLACR1, Nbla10727, Nbla12061 and UC.388 were up-regulated and LSINCTS was down-regulated. The expression of ATB,EBIC, HOTAIR, PVT1, LET, Loc285194 and SRHC was less than 2-fold of DDH control. Conclusions Low expression of PRNCR1 was observed in bone tissue from OI patients. The functions of PRNCR1 in OI need further study.
