Figure Lengend Snippet: IFI16 inhibits AAV2 gene expression in an Sp1-dependent manner. U2OS IFI16 -/- and U2OS wt cells were either untransduced (U2OS IFI16 -/- or U2OS wt, respectively), transduced with lentiviral vectors expressing GFP (MOI 5; U2OS IFI16 -/- + GFP ctrl.), or transduced with lentiviral vectors expressing IFI16 fused to monomeric GFP (MOI 5; U2OS IFI16 -/- + IFI16_GFP). After 72 hours, the cells were infected with AAV2 (MOI 20,000) and 24h later subjected to ChIP assays using an anti-Sp1 antibody and primers for the ( A ) p5 or ( B ) p19 promoter regions, respectively. ( C ) Interaction of IFI16 and Sp1 was assessed by co-immunoprecipitation in U2OS wt and U2OS IFI16 -/- cells. Graphs show mean and SD of the relative promoter occupancy from triplicate experiments. P -values were calculated using an unpaired Student’s t -test (* P ≤ 0.05, ** P ≤ 0.01, *** P ≤ 0.001, and **** P ≤ 0.0001).
Article Snippet: Lentiviral vectors expressing GFP (TR30021V) or IFI16 fused to monomeric GFP (RC202193L2V) were obtained from OriGene (Rockville, USA).
