CEM87-mediated induction of GFP transgene expression following AAV vector transduction. (A) Mean fluorescence intensity of HCT116 cell infected with AAV2 +ZF-FKBP_GFP then treated with 0–1,000 nM of CEM87. (B) Mean fluorescence intensity of U2-OS cells infected with AAV2 +ZF-FKBP_GFP then treated with 0–1,000 nM of CEM87. (C) Mean fluorescence intensity of HEK293T cells infected with AAV2 +ZF-FKBP_GFP then treated with 0–1,000 nM of CEM87. (D) Phase and fluorescent images of HEK293T cells either infected with AAV2 +ZF-FKBP_GFP or no virus and then treated with 0 or 500 nM of CEM87. Images were taken at 40 × magnification. p Value parameters: **p ≤ 0.01, ***p ≤ 0.001, ****p ≤ 0.0001. GFP, green fluorescent protein; ZF, zinc finger protein.
