Figure 2. Venn analysis of gene expression changes associated with HDACi treatment of differentiated midbrain cultures.

Figure 2

Differentiated midbrain cultures were treated with 330 nM TSA, 50 mM SB or 50 mM VPA respectively for 48 hours and gene expression was analyzed using Agilent whole mouse genome expression microarray chips. Genes with a p-value of <0.02 were considered differentially expressed (DEGs) and subjected to Venn analysis. (A) A total of 895 genes are up-regulated by HDACi treatment. A subset of 127 of these genes are up-regulated by all three drug. (B) A total of 1360 genes are down-regulated as a result of HDACi treatment, with a subset of 373 genes being down-regulated by all three drugs. Numbers represent the total number of modulated genes in that experimental condition.
