LncRNA PRNCR1 regulates osteogenic differentiation in osteolysis after hip replacement by targeting miR-211-5p
©2018 The Author(s)..
Background Osteogenic differentiation and osteolysis after hip replacement are both associated with bone metabolism. Interaction between the long non-coding RNA (lncRNA) prostate cancer non-coding RNA 1 (PRNCR1) and miR-211-5p was analyzed to illuminate their roles in osteogenic differentiation and osteolysis. Methods The expression of PRNCR1, miR-211-5p and C-X-C chemokine receptor-4 (CXCR4) protein in tissues and mesenchymal stem cells (MSCs) were determined by qRT-PCR and western blot, separately. The osteogenic differentiation was assessed with Alkaline phosphatase (ALP) activity detection and ARS staining. The endogenous expressions of genes were modulated by recombinant plasmid and cell transfection. Combination condition and interaction between RNA and protein were determined with RIP and RNA pull-down assay, respectively. Interaction between miR-211-5p and CXCR4 was examined with Dual luciferase reporter assay. Results PRNCR1 and CXCR4 were up-regulated in wear particles around prosthesis and in MSCs incubated with Polymethylmethacrylate (PMMA), while miR-211-5p was down-regulated. Repression of PRNCR1 weakened the inhibitory effect of wear particles on osteogenic differentiation. PRNCR1 positively regulated CXCR4 through inhibiting miR-211-5p. Wear particles regulated CXCR4 level through miR-211-5p to affect osteogenic differentiation of MSCs. Wear particles regulated the miR-211-5p level through PRNCR1 to affect osteogenic differentiation of MSCs. Conclusion LncRNA PRNCR1 up-regulates CXCR4 through inhibiting miR-211-5p, which inhibits osteogenic differentiation and thereby leading to osteolysis after hip replacement.
