Figure 5From: Utilization of IκB–EGFP Chimeric Gene as an Indicator to Identify Microbial Metabolites with NF-κB Inhibitor Activity The mechanism used by HQ prevents the degradation of IκB proteins. The amount of intracellular unphosphorylated and phosphorylated IκB proteins of 5–100 μM HQ-treated 293 cells was detected by Western blot. The quantity of IκB and phosphorylated IκB proteins was induced by different dosages of HQ.Back to article page
