Figure 3

Effect of NF-κB inhibitor on the viability of HBEC exposed to cigarette smoke extract. Cells were pre-treated with 20 μM curcumin for 30 minutes followed by exposure to 10% cigarette smoke extract for 24 hours in the presence or absence of curcumin. Cell viability and cytotoxicity were determined by LIVE/DEAD assay. Panel A: One representative micro-photograph of LIVE/DEAD staining. Green: live cells; Red: dead cells. Magnification: 200×. Panel B: Quantitative data from 3 separate experiments. Vertical axis: percent of dead cells = red cells/(green cells + read cells) * 100%. Horizontal axis: treatment.
