Summary of pairwise comparisons for genes affected in shRNA T2 and shRNA T1 infected HeLa cells. The Venn diagram represents the following individual pairwise comparisons: down regulated genes- shRNA T2 (blue circle) vs. shRNA T1 (orange circle), up regulated genes- shRNA T2 (purple circle) vs. shRNA T1 (green circle) each compared to shRNA MM. Number in parentheses represents the total number of genes whose expression was changed for that comparison. The numbers within each circle represents the genes unique to that comparison. The number in the intersection of the gene sets representing the shared genes whose expression was changed is indicated.
