Figure 2. (A, B, C) Effect of the diatom PUA 2-trans,4-trans-octadienal (OD) on the human lung adenocarcinoma cell lines A549 and COLO 205, and the lung/brunch normal epithelial BEAS-2B cell line.

(D) Effect of OD on A549 cell line in the presence of caspase-3 inhibitor (9.7 µM). Percentage of viable cells for A549 and COLO 205 calculated with the Trypan blue viability assay and for BEAS-2B with the MTT viability assay. Values are reported as mean ±S.D compared to controls (100% viability); ▴ 2 µM; ▪ 5 µM, ♦ 10 µM.
