Fig. 6From: Regulation of voltage-gated potassium channels attenuates resistance of side-population cells to gefitinib in the human lung cancer cell line NCI-H460Inhibition of the EGFR-Ras-Raf signaling pathway on NCI-H460 cells with combination treatment. The protein expression level of p-EGFR, total Ras, p-Raf, and p-ERK1/2 was inhibited in cells with gefitinib and Kv blockers (TEA and 4-AP) or an opener (flupirtine)Back to article page
