1 Voltage-gated K+ channel blocker quinidine inhibits proliferation and induces apoptosis by regulating expression of microRNAs in human glioma U87-MG cells. Quinidine potassium voltage-gated channel subfamily D member 3 Homo sapiens
2 In the present study, we investigated the effect and mechanisms of quinidine, a commonly used voltage-gated K+ channel blocker, on cell proliferation and apoptosis of human glioma U87-MG cells. Quinidine potassium voltage-gated channel subfamily D member 3 Homo sapiens
3 Furthermore, the concentration range of quinidine, which inhibited voltage-gated K+ channel currents in electrophysiological assay, was consistent with that of quinidine inhibiting cell proliferation and inducing cell apoptosis. Quinidine potassium voltage-gated channel subfamily D member 3 Homo sapiens
4 Furthermore, the concentration range of quinidine, which inhibited voltage-gated K+ channel currents in electrophysiological assay, was consistent with that of quinidine inhibiting cell proliferation and inducing cell apoptosis. Quinidine potassium voltage-gated channel subfamily D member 3 Homo sapiens
5 Taken together, these data suggested that the anti-proliferative and pro-apoptosis effect of voltage-gated K+ channel blocker quinidine in human glioma cells was mediated at least partly through regulating expression of miRNAs, and provided further support for the mechanisms of voltage-gated K+ channels in mediating cell proliferation and apoptosis. Quinidine potassium voltage-gated channel subfamily D member 3 Homo sapiens
