HOTAIR regulates CXCL12 expression by competitively sponging miR-107. A and B The abundances of CXCL12 at mRNA and protein levels were measured in chondrocytes transfected with si-NC, si-HOTAIR, si-HOTAIR + in-miR-NC or in-miR-107 by qRT-PCR and western blot at 24 h post-transfection. n = 3. Data were expressed as mean ± S.D. *P < 0.05
