A, Western blot of whole cell lysates from Scr and RNF121 KO cell lines. B, Luciferase reporter expression of Scr and RNF121 KO Huh7 cells following transduction with AAV1 (10,000 vg/cell), AAV2 (5,000 vg/cell), AAV6 (10,000 vg/cell), and AAV9 (20,000 vg/cell). C, Luciferase reporter expression of Scr and RNF121 KO in HEK293 and U87 cell lines following transduction with AAV2. D, Luciferase reporter signal with increasing dose of AAV2 on Scr and RNF121 KO Huh7 cells. E, Luciferase reporter signal of Scr and RNF121 KO HEK293 cells following transfection with a control plasmid or plasmid containing RNF121 cDNA. A two-tailed unpaired t test was used unless otherwise indicated, with *, p<0.05; **, p<0.01; ***, p<0.005.
