Effect of decynium‐22 and corticosterone on mOct3 transport activity. CHO‐K1 cells overexpressing mOct3 were incubated with 100 nm MPP⁺ and decynium‐22 and corticosterone for 5 min at 37 °C. MPP⁺ transport activity is expressed relative to that in untreated control cells. Individual transport assays were performed in triplicate (three wells were analyzed for each group per trial). The results were confirmed at least two times in separate experiments using different cryopreserved cell vials. The results shown are representative of experiments performed.
