Figure 7. Fructus Ligustri Lucidi (FLL) inhibits NF-κB activation and CatK expression in the tibias and femurs of aging mice. The representative images of immunohistochemical staining (original magnification, ×200, ×400) and western blot, and their analyses showed the acetylation of NF-κB-p65 (A–B), relative expression of NF-κB-p65 acetylation to NF-κB-p65 (C–D) and CatK (C, E–G) in the femurs and tibias. Data are presented as mean ± SD. # compared with the normal group. * compared with the aging model group. p < 0.05 was considered statistical difference, n=6.
