Fig 8. mRNA expression levels of OPG, RANKL and RANK after microRNA (miR)-145 overexpression at different time points.

Note: a, compared to 0 h, P < 0.01; b, compared to 0 h, P < 0.01; RANKL, receptor activator of nuclear factor-κ B ligand; OPG, osteoprotegerin; RANK, receptor activator of nuclear factor-κ B; experiments were repeated 3 times, and means were obtained.
