Effect of A. bidentata extract (AE) on antimycin A-induced cytokines production of MC3T3-E1 cells. Osteoblasts were pre-incubated with AE before treatment with 70 μM antimycin A (AMA) for 48 h. Data were expressed as percentage of control. The control values for TNF-α (a), IL-6 (b), and RANKL (c) were 0.228 ± 0.006, 0.655 ± 0.033, and 3.378 ± 0.074 ng/mg, respectively. *P < 0.05; control versus AMA, #
P < 0.05; antimycin A versus AE
