Gene expression quantification in MM-231 cells.

<p>Normalized data show a significant increase in seven genes in the TNF-α-stimulated MM-231 cells vs. resting cells. On the other hand, nine genes were significantly repressed in cotreated cells. The data points are expressed as the mean ± SEM of three independent studies. The significance of the difference was determined by an unpaired t-test between the resting vs. TNF-α-activated cells (*), as well as TNF-α-treated vs. TNF-α + PL-treated cells (#). Significance is considered at *p < 0.05, **p < 0.01, ****p < 0.0001, #p < 0.05, ##p < 0.01, and ###p < 0.001 or the difference was nonsignificant (ns).
