a Viral attachment 1 h post infection (hpi) measured by qPCR for viral Hexon over time following carvedilol (10 μM) treatment in OVCAR4 (n = 4 biological repeats) and Ov4carbo (n = 5 biological repeats) cells (ns P > 0.05). b Flow cytometry analysis of viral infectivity. Percentages of GFP positive OVCAR4 and Ov4Carbo cell populations measured 24 h after treatment with AD5-GFP (MOI 10) and carvedilol (10 μM) (n = 2 biological repeats; 10,000 events; ns P > 0.05). c) Representative western blot images of viral protein expression in Ov4Carbo cells following treatment with dl922-947 (MOI 1) and carvedilol (10 μM) 96-144 hpi. d, e Densitometry analysis of viral protein expression, expressed as ratios of d E1A/Hsc70 and e adenovirus structural proteins (Hexon + Penton + Fibre + core)/GAPDH (n = 5 biological repeats; mean ± SEM; paired t-test, *P ≤ 0.05). f Viral replication in Ov4Carbo cells following treatment with dl922-947 (MOI 1) and carvedilol (10 μM) 96-144 hpi as measured by qPCR for adenoviral Hexon (n = 6 biological repeats; mean ± SEM; paired t-test, *P ≤ 0.05). g, h Viral titre in Ov4Carbo cells following treatment with dl922-947 (MOI 1) and carvedilol (10 μM) 120 hpi (g) and 144 hpi (h), measured by TCid50 (120 hpi: n = 4; 144 hpi: n = 3 biological repeats, geo mean ± 95% CI; data displayed as technical triplicates from each individual biological repeat assay).
