Representative in vivo images of mice bearing fluorescent tumors on day 42 (Fig. 7B) confirmed that the tumor weight in the KIF18B-DU145-injected group was heavier than those in the Vector-DU145-injected group (median: 0.0775 g for Vector-DU145 vs 0.322 g for KIF18B-DU145, P < 0.05, Fig. 7C) and the tumor volume was also larger in the KIF18B-DU145-injected group compared with the Vector-DU145-injected group (median: 56.55 mm3 for Vector-DU145 vs 368.8 mm3 for KIF18B-DU145, P < 0.001; Fig. 7D). The gene discussed is KIF18B; the disease is neoplasm.
