Cell counting assays also showed that ARHGAP42‐pcDNA3.1 vector was transient transfected could reverse the NPC cell lines CNE2 proliferation inhibition caused by uc010rul‐specific silence in Figure 6D. In migration and invasion test, we found that uc010rul‐siRNA‐transfected cells migrated and invaded significantly less (P < .01), but overexpressed ARHGAP42‐transfected reversed the effect incompletely (P < .01) in Figure 6E,G,H. The gene discussed is ARHGAP42; the disease is nasopharyngeal carcinoma.
