Comparison between datasets representing genes up-regulated in cells expressing Hoxa9 + Meis1 and Hoxa9 + Pknox1-MC. (A) The overlap between genes up-regulated in the Meis1 + Hoxa9 and Pknox1-MC + Hoxa9, but not in the Pknox1 + Hoxa9 cells, compared with the parental Hoxa9 cells is shown by Venn diagram. (B) Enrichment for GO terms associated with various biological processes in the gene datasets defined in A (group IV, V, and VI), was performed as described for Figure 5C.
