B. Genes of the Hallmark gene set "Oxidative phosphorylation" that are differentially expressed in low STAT3 vs. high STAT3 tumors. Dotted lines show Log2-FC = ±1 (x-axis) and adj. p-value = -log10(0.05) (y-axis). Orange = up-regulated genes, green = down-regulated genes. DE = differentially expressed.
