J82 and J82-Ras cells were treated with Rom+Cis+Gem at their IC10 doses for J82-Ras cells for 48 h to induce differential cell death. a Heatmap of 179 differentially expressed genes (>2-fold change, FDR < 0.05), induced by Rom+Cis+Gem, that are functionally associated with ROS, cell death, or drug resistance. Colour code represents the z-score of the expression. b Venn diagram of differentially regulated genes, induced by Rom+Cis+Gem, functionally associated with ROS, cell death, drug resistance, DNA repair, autophagy, or drug transport in J82 and J82-Ras cells were compared. c Quantification of upregulated ROS-, cell death-, and drug resistance-associated gene expression levels. Upper panel shows the folds of increases. Lower panel shows the associated p values. Fisher’s exact test was used to obtain statistical significance: *p < 0.05, **p < 0.01, not significant (NS) p > 0.05.
