The effect of DPP-4 inhibitor on expressions of RANKL, TNF-α, OPG, and RANKL/OPG ratio in vivo. (a–d) Relative expression levels of RANKL, TNF-α, and OPG mRNA in mouse alveolar bone detected by real-time PCR. RANKL, TNF-α, and OPG mRNA levels were normalized to the levels of GAPDH. for each group. ; .
