AP-1-Targeting Anti-Inflammatory Activity of the Methanolic Extract of Persicaria chinensis

Figure 6

Effect of quercetin on the activation of upstream signaling enzymes of AP-1 in a reporter gene assay. The promoter binding activity of the transcription factor AP-1 was analyzed using a reporter gene assay in HEK293 cells transfected with plasmid constructs AP-1-Luc (1 μg/mL) and β-gal (as a transfection control) with 1 μg/mL of MyD88 in the presence of quercetin. Luciferase activity was measured using a luminometer. compared with control.
