**1. Introduction**

The aim of our research is based on the design of therapeutic approaches that make use of the Kv10.1 voltage-gated channel as a target. Kv10.1 is a voltage-gated potassium channel, which was discovered in the 60s and has been the main focus of our electrophysiological and molecular biology research for many years. During our early experiments, we discovered, contrary to the typical perspective of a voltagegated ion channel, that Kv10.1 plays a key role in the development of tumors, and even though there is still a lot to understand about how Kv10.1 helps tumor cells to survive, we have been able to unravel many of its mechanisms. An overview of those discoveries will be presented in the present work.
