KCNQ potassium channels modulate Wnt activity in gastro-oesophageal adenocarcinomas
Introduction The KCNQ (potassium voltage-gated channel subfamily Q) family of ion channels encode potassium transporters (1). KCNQ proteins typically repolarise the plasma membrane of a cell after depolarisation by allowing the export of potassium ions, and are therefore involved in wide-ranging biological functions including cardiac action potentials (2), neural excitability…
