Preventive Effects of Chrysanthemum coronarium L. Extract on Bone Metabolism In Vitro and In Vivo

Figure 5

The effect of Chrysanthemum coronarium on receptor activator nuclear-factor κB ligand-induced osteoclastic gene expression in the murine macrophage-like cell line RAW 264.7. (A–D) The cells were cultured with receptor activator nuclear-factor κB ligand (RANKL) (50 ng/mL) at various concentrations of CC for 4 d and osteoclast-specific gene expression was determined. (a) Cathepsin K. (b) Tartrate-resistant acid phosphatase (TRAP), (c) dendritic cell-specific transmembrane protein (Dc-Stamp), and (d) calcitonin receptor (CTR) expressions were analyzed using RT-qPCR. RNA expression levels were normalized to those of glyceraldehyde 3-phosphate dehydrogenase (GAPDH). Data represent means ± SD, n = 3; compared with the control group, , , and compared with the RANKL treatment group.
