Effects of Bay 11-7082 (Bay; NF-κB inhibitor), piperlongumine (PL), and NAC on proliferation of MCF-7 cells. Cells were treated with Bay 11-7082 (10 and 20 µM) or PL (10 and 20 µM) for 24 h, with or without NAC pretreatment (5 mM, 1 h). An MTT assay was performed to determine the number of viable cells. Data represent the mean ± SEM (n = 4). * Significantly different compared with the control (p < 0.05). # Significantly different compared to 20 µM of PL (p < 0.05).
