Kang C, Li X, Yang X, Cheng X, Zhang D, Wei X. Voltage-gated potassium channels associated with head and neck cancer. Biochim Biophys Acta Rev Cancer 2025; 1880:189340. [PMID: 40318770 DOI: 10.1016/j.bbcan.2025.189340] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2024] [Revised: 04/28/2025] [Accepted: 04/28/2025] [Indexed: 05/07/2025]
Abstract
Head and neck cancer (HNC) is a common disease in otorhinolaryngology. Its prevalence is higher in men than in women and is mostly related to tobacco, alcohol and viral infections. Despite significant advances in the treatment of HNC in recent years, the mortality rate is still high and most patients are diagnosed at an advanced stage, and the prognosis for these patients is even worse. Earlier metastasis makes the treatment of HNC trickier. Therefore, actively seeking ways to treat HNC more effectively has been the goal of head and neck surgeons. Potassium (K+) channels are the most diverse ion channels found in all areas of life. Voltage-gated potassium (Kv) channels are the most important subfamily of K+ channels. Multiple Kv channels are associated with the development of HNC. This review focuses on several Kv channels associated with HNC.

[PMID: 40112771 DOI: 10.1016/j.neuron.2025.02.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2025] [Revised: 02/19/2025] [Accepted: 02/19/2025] [Indexed: 03/22/2025]
Abstract
Primary brain tumors induce neuronal hyperexcitability, leading to epileptic seizures. In this issue of Neuron, Goldberg et al.1 demonstrate genetic, structural, and functional alterations to excitatory tumor-associated neurons and how mTOR inhibition rapidly reverses these changes in a mouse model.

Abstract
Writing in Neuron, Zhang et al. identify a subpopulation of glioblastoma cells from patient tumor samples with progenitor-like features that expresses the potassium ion channel KCND2.1 In mouse and organoid models, these cells enhance neural activity at the glioma-neural interface.
