Background:
Ion channels are drug targets for many diseases but have only recently started to be regarded as potential primary cancer targets. Many types of ion channels have been identified that could be useful in cancer management.
Objective:
We focus on a voltage-gated potassium channel, ether à go-go 1 (Eag)1, which shows distinctive features such as a restricted expression pattern and peculiar electrophysiological properties.
Methods:
We review the literature on this channel and try to relate this knowledge to the context of other ion channels in cancer.
Results/Conclusion:
Eag1 appears to be a promising cancer target, both as a tumor marker because of restricted expression, which could be useful in the context of therapeutic decisions, and as a therapeutic-agent-targeting molecule.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
