After 4 weeks, the tumor growth was significantly delayed in the H1299-PARK2 group relative to the H1299-NC group, and the tumor volume and tumor weight of the two groups were 1531 ± 211.8 vs. 2665 ± 351.0 mm3 and 1.51 ± 0.23 vs. 2.41 ± 0.33 g (P < 0.05; Figure 5A). This evidence concerns the gene PRKN and neoplasm.
