In addition, the effects of siKIF4A on glioma cell migration and invasion were quantified by Transwell assays, and as shown in Fig. 4D and Supplementary Fig. 1E, siKIF4A treatment significantly suppressed glioma cell migration and invasion.These observations revealed that KIF4A knockdown exerted an antiglioma effect. The gene discussed is KIF4A; the disease is glioma.
