With Venny 2.0.2, we identified 660 genes that were differentially expressed in both data sets, with the majority (578 genes, called “reverse DEGs” below) showing a reversal of leukemia-associated expression changes in the Mbd2−/− cells (P = 1×10−16, calculated using the R package SAGx_1.32.0 under R version 2.15.3). This evidence concerns the gene MBD2 and leukemia.
