BACKGROUND: Endometrial cancer is the most common gynecological cancer in developed countries. Potassium channels, which have many types, are suggested to play a major role in cancer progression. However, their role in endometrial cancer has not been fully investigated. We aimed to demonstrate whether the ATP-sensitive potassium channel blocker glibenclamide, voltage-sensitive potassium channel blocker 4-aminopyridine, non-selective (voltage-sensitive and calcium-activated) potassium channels blocker tetraethylammonium and potassium chloride (KCl) have any effect on the proliferation and migration of HEC1-A cells.
METHODS AND RESULTS: Proliferation and migration were evaluated by real-time cell analysis (xCELLigence system) and wound healing assays, respectively. Proliferation was reduced by glibenclamide (0.1 and 0.2 mM, P < 0.05 and P < 0.01, respectively), 4-aminopyridine (10 and 20 mM, P < 0.001) and tetraethylammonium (10 and 20 mM, P < 0.01 and P < 0.001, respectively). However, KCl did not change the proliferation. Migration was reduced by glibenclamide (0.01, 0.1 and 0.2 mM, P < 0.001, P < 0.001 and P < 0.01, respectively) and 4-aminopyridine (10 and 20 mM, P < 0.05 and P < 0.01, respectively). Tetraethylammonium did not change migration. However, KCl reduced it (10, 25 and 50 mM, P < 0.05, P < 0.01 and P < 0.01, respectively). Both proliferation and migration were reduced by glibenclamide and 4-aminopyridine. However, tetraethylammonium only reduced proliferation and KCl only reduced migration.
CONCLUSIONS: Potassium channels have an important role in HEC1-A cell proliferation and migration and potassium channel blockers needs to be further investigated for their therapeutic effect in endometrial cancer.
