Voltage-gated K+ channels, human ether-a-go-go-related channel (hERG, also known as Kv11.1 and encoded by the gene KCNH2), and hEAG (human ether a-go-go, Kv10.1, KCNH1) are expressed in gliomas where they have been shown to control proliferation and apoptosis [140]. This evidence concerns the gene KCNH1 and glioma.
