As shown in Figure 6A, the Ad-NDRG2 group achieved a sustained and significant inhibition of tumor growth compared with Ad-LacZ group (P value is 0.002, 1.54 ×10-6, 1.77 ×10-6, 9.7 ×10-11, 8.69 ×10-12 and 1.35 ×10-9 at Day6, 9, 12, 15, 18 and Day 21 respectively). Here, NDRG2 is linked to neoplasm.
