The left panel shows the timeline of drug exposure experiments. (A-D) Images show vRNA and vDNA in an infected ThP1 cell (MOI 20) for each of four experimental conditions. See Appendix Fig. S15-S17 for images of larger regions. (A,B) ThP1 cells were exposed to NVP for 48 h (A) or 72 h after infection (B), then NVP was washed out, and cells were fixed for click chemistry 24 h later. (C) Cells were exposed to PF74 for 72 h after infection, then fixed for click chemistry. (D) Cells were exposed to NVP for 24 h after infection, then NVP was washed out, and cells were exposed to PF74, before being fixed for click chemistry 24 h later. (E,F,H) Scatter plots show vDNA and vRNA intensities in colocalizing clusters with Spearman correlation r and associated p-values. Replicates of the four experiments yielded similar results. (G) qPCR measures DNA synthesis (left) and nuclear import (right) at 72 h p.i. in absence of drug treatment, or after exposure to NVP or PF74. Bars and error bars define mean and standard deviation, respectively. Samples were analyzed in triplicate and two biological replicates were performed.
