E. coli ZYCY10P3S2T transformed with pMC.BESPX- HPV18 were induced to generate minicircles.Plasmid DNA isolated before and after induction was digested with BglII. DNAs were separated on a 0.8% TAE agarose gel and imaged on a UV lightbox. Lane 1: Pre-induction pMC.BESPX-HPV18, undigested; lane 2: pre-induction pMC.BESPX-HPV18, digested; lane 3: post-induction pMC.BESPX-HPV18, undigested;lane 4:post-induction pMC.BESPX-HPV18, digested.CCC, covalently closed circular DNA.

HPV18(+) cells produce more cGAMP than parental control cells. Quantification of cGAMP by ELISA following DNA stimulation of HPV(-) cells (black) and HPV18(+) cells (red). N=3 donors, 3 reps in each donor, average of the 9 replicates, (A) replicates separated by donor (B). Statistics for (A) were calculated using a linear mixed-effects model with “HPV” and “Time” as fixed effects and donor as a random effect to account for inter-donor variability. Statistics for (B) were calculated with a two-way ANOVA followed by a Dunnett’s post hoc test. * p<0.05; ** p<0.01; *** p<0.001Error bars for represent SEM, calculated by first averaging technical replicates (n=3 per donor) with propagated error, and then computing SEM across biological replicates (n=3 donors).
