Figure 2From: Antineoplastic effects of the DNA methylation inhibitor hydralazine and the histone deacetylase inhibitor valproic acid in cancer cell linesHierarchical clustering revealed specific patterns induced by each treatment. Hydralazine, valproic acid and the combination down-regulated a similar set of genes. On the contrary, up-regulated genes were distinctive for each treatment. From 1,281 differentially expressed genes, 651 were up-regulated and 630 down-regulated. The number of genes over-expressed specific of hydralazine, valproic acid and the combination were 153, 178 and 352. Each row represents a gene, whereas each column corresponds to the treatment drug. The relative abundance of the gene in the tissue correlates with color intensity; red induced; green repressed; black no change. H: hydralazine, V: valproic acid, and HV: hydralazine and valproic acid.Back to article page
