Fig. 1. PBQC up regulated Nrf2 activity. (A) PBQC molecular structure is shown. (B) HeLa cells were stably transfected with ARE–luciferase reporter gene, and incubated Luci–HeLa cells with 0.1% DMSO (control) or PBQC at 1, 5, 10 μM for 6, 12, 24 and 48 h. The cell viability was analyzed by SRB assay and Luci–HeLa cells were lysed and luciferase activities were measured, setting the control group activity to 1. (*p < 0.05, **p < 0.01, ***p < 0.001, vs. control, n = 3).
