KIF3B and neoplasm: The results showed that the tumor size (812.67 ± 74.78 mm3vs. 1370.67 ± 66.01 mm3, P < 0.05, Figures 7A, B) and weight (196.10 ± 46.78 mg vs. 431.70 ± 57.78 mg, P < 0.01, Figure 7C) in KIF3B-shRNA cell xenografts were significantly reduced compared with the Scr-shRNA group; however, hematoxylin and eosin (HE) staining of the xenografts showed no significant difference (Figure 7D, left: ×100 Scr-shRNA group ×400; right: KIF3B-shRNA group ×400).
