As shown in Figure 8C, the inoculated ELK1-shRNA tumors were smaller than control-shRNA tumors, especially after day 5, although the differences in tumor size between the two groups did not narrowly reach statistical significance (P > 0.1 at days 1–8; P = 0.056 at day 9; P = 0.069 at day 10). This evidence concerns the gene ELK1 and neoplasm.
