To verify whether CA916798 participated in the regulation of LUAD response to Gefitinib, PC9/R and HCC/R cells were stably infected by lentivirus including shRNA targeting CA916798 (PC9/R-siCA and HCC/R-siCA) or control shRNA (PC9/R-siCtrl and HCC/R-siCtrl) (Fig. 5E F). Here, C19orf48P is linked to hepatocellular carcinoma.
