Abstract

It is noteworthy that some ion channels are overexpressed in cancer cells. One of these ion channels is the Ether à-go-go 1 (KCNH1, Kv10.1) (Eag1 K+) channel. In this study, cytotoxic and electrophysiological effects of different concentrations of tricyclic antidepressant, Imipramine, on Eag1 K+ channels were investigated in MCF-7 cell line (breast cancer cell). Its cytotoxic effect was investigated by MTT analysis method, and its electrophysiological effect was researched by patch-clamping technique. By MTT analysis, it was determined that 20 µM and higher concentrations of Imipramine on MCF-7 cells, had an approximately 85% suppressive effect, compared to the control group. On the other hand, in patch-clamping experiments, 2μM, 5μM and 20μM effects on Eag1 K+ channels were investigated. It has been shown that low-dose, 2μM Imipramine, inhibits Eag1 K+ channel currents by approximately 75% and its high-dose, 20μM, inhibits the channel currents by approximately 82%, compared to the control group.

Özet

Kanser hücrelerinde bazı iyon kanallarının aşırı eksprese edilmesi dikkat çekmektedir. Bu iyon kanallarından biri de Ether à-go-go 1 (KCNH1, Kv10.1) (Eag1 K+) kanalıdır. Bu çalışmada, MCF-7 hücre hattında (meme kanseri hücresi) trisiklik antidepresan olan imipraminin farklı konsantrasyonları kullanılarak, Eag1 K+ kanalları üzerine sitotoksik ve elektrofizyolojik etkileri incelenmiştir. Sitotoksik etkisi MTT analiz yöntemiyle, Elektrofizyolojik etkisi ise yama-kenetleme tekniği ile araştırılmıştır. MTT analiz yöntemiyle imipraminin MCF-7 hücreleri üzerinde kontrol grubuna göre 20μM ve üzeri konsantrasyonlarının yaklaşık %85 oranında baskılayıcı etkiye sahip olduğu belirlenmiştir. Yama-kenetleme deneylerinde MCF-7 hücrelerine 2μM, 5μM ve 20μM imipramin uygulanarak Eag1 K+ kanalları üzerine etkisi incelenmiştir. Düşük doz olan 2μM imipraminin kontrol grubuna göre Eag1 K+ kanal akımları yaklaşık %75 ve yüksek doz olan 20μM imipramin’in Eag1 K+ kanal akımlarını yaklaşık %82 gibi yüksek oranda inhibe ettiği gösterilmiştir.
