Changes in K channel expression (protein) by testosterone. Expression of Kv7.1 (a), Kv4.2 (b), and Kir2.1 (c) as assessed by western blot analysis. Testosterone was intraperitoneally administered (1000 µg/kg) once a day for 2 weeks from day 7 after castration. Data were expressed as mean ± SEM (n = 4). *p < 0.05 vs control (castration)
