Inhibitory effects of CC34 on the NF-κB signaling pathway. A Phosphorylated and total protein levels of NF-κB in RAW264.7 cells were analyzed via western blot. In B–D, the relative protein levels of phospho-IKKβ/IKKβ, phospho-IκBα/IκBα, and phospho-NF-κB/NF-κB in cells are shown. Data are presented as mean ± SD (n = 3). The differences between groups were assessed using ANOVA followed by Duncan’s test. Compared to control: *P < 0.05, **P < 0.01. Compared to LPS: #P < 0.05, ##P < 0.01
