KCNH2 and infection: Contemporaneously cultured aGPVMs infected with adenovirus encoding WT mCherry-BBS-hERG-YFP (infections carried out 2 h after isolation) displayed both mCherry and YFP fluorescence (Figures 4D and 4E) and did not significantly affect action potential duration (APD80 = 423.5 ± 45.6, n = 12, p = 0.41, one-way ANOVA and Dunnett’s multiple comparisons test) compared with uninfected cells (Figures 4F and 4J).
