Figure 3. Effects of Kv1.5 siRNA adenoviral Kv1.5 overexpression on endogenous Kv1.5 protein expression in HPAECs.

(A). HPAECs were treated with 2.5, 5, 10 nM Kv1.5 siRNA for 48 h and Kv1.5 protein expression was analyzed by western blot. * P<0.05, ** P<0.01 vs. Vehicle control, n = 3. (B). HPAECs were infected with adnovirus containing KCNA5 (Ad-Kv1.5) and control–adnovirus (Ad-con) for 12, 24, 48 h. * P<0.05, ** P<0.01 vs. Ad-con at corresponding time points, n = 3.
