Biological process pathways identified by DAVID as enriched for Class 1 or Class 2 genes hyperacetylated in low- or high-migrating cells, respectively (adj. P-value < 0.05 for Class 1 and P-value < 0.05 for Class 2). Dots represent GO term enrichment with color coding: red for high enrichment, blue for low enrichment, and sizes of the dots representing the significance score of each subset (the bigger the dot, the higher its significance).
