rAAV2.5 transduction of individual gene knockout HeLa cells. Eleven candidate genes (KIAA0319L, TM9SF2, ZNF320, KYAT3, NPHP3, WDR63, PDE4A, OR51M1, GPR174, CCDC92, and MSMO1) were selected based on the shRNA knockdown screening. A gRNA-expressing lentiviral vector was applied to HeLa cells, and single-cell cloning was carried out to generate a knockout cell line. (A) Western blotting. Western blots show the knockout efficiency at 3 days post-transduction. β-Actin was used as a loading control. (B) Luciferase activities in gene knockout HeLa cells. Gene knockout cells were transduced with rAAV2.5T at an MOI of 20,000 DRPs/cell. At 3 days post-transduction, the luciferase activities were measured. The red dashed line indicates 50% of the luciferase activity in non-target control HeLa cells. Data shown are means with an SD from three replicates.
