ABSTRACT
Background: Expression and activity of the potassium channel ether-à-go-go-1 (EAG1) are strongly related to carcinogenesis
and tumor progression, which can be exploited for therapeutic purposes. EAG1 activity may be reduced by preventing its phosphorylation
with epidermal growth factor receptor (EGFR) kinase inhibitors and by astemizole, which blocks the channel pore
and downregulates its gene expression.
Objective: We aimed to study the potential cooperative antiproliferative effect of the
EGFR inhibitor gefitinib and the EAG1-blocker astemizole, in breast cancer cells.
Materials and Methods: The cells were characterized
by immunocytochemistry. Inhibitory concentrations were determined by non-linear regression analysis using doseresponse
curves. The nature of the pharmacological effect was evaluated by the combination index equation while cell cycle
analysis was studied by flow cytometry.
Results: Astemizole and gefitinib inhibited cell proliferation in a concentration-dependent
manner, with inhibitory concentrations (IC 50) values of 1.72 µM and 0.51 µM, respectively. All combinations resulted in a
synergistic antiproliferative effect. The combination of astemizole and gefitinib diminished the percentage of cells in G2/M and
S phases, while increased accumulation in G0/G1 of the cell cycle.
Conclusions: Astemizole and gefitinib synergistically inhibited
proliferation in breast cancer cells expressing both EGFR and EAG1. Our results suggest that the combined treatment increased
cell death by targeting the oncogenic activity of EAG1.
