However, the clinical development of Kv10.1 inhibitors is currently constrained by severe off-target cardiotoxicity resulting from unintended inhibition of the structurally homologous Kv11.1 (hERG) channel. In this review, we examined cancer-associated membrane lipid remodelling and its implications for the lipid-dependent regulation of both channels. Emerging evidence suggests that membrane lipids play a critical role in regulating voltage-gated potassium channels and that, despite their substantial structural similarity, Kv10.1 and Kv11.1 are modulated by distinct lipid-dependent mechanisms. In particular, we highlighted their differential responses to key membrane constituents, including phosphatidylinositol 4,5-bisphosphate (PIP2), cholesterol, and polyunsaturated fatty acids (PUFAs). These observations suggest that the surrounding membrane environment may represent an additional and largely underexplored factor influencing channel function. We further discuss how disease-associated lipid remodeling in cancer may contribute to altered Kv10.1 activity and highlight the possibility that such changes could influence pharmacological responses. Although the underlying mechanisms remain incompletely understood, this perspective points to an underexplored dimension in potassium channel biology that may inform future therapeutic strategies.<\/jats:p>","DOI":"10.3389\/fphar.2026.1905919","type":"journal-article","created":{"date-parts":[[2026,9,3]],"date-time":"2026-09-03T06:40:41Z","timestamp":1788417641000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Lipid-dependent regulation of Kv10.1 in cancer: implications of membrane remodeling for channel function and pharmacology"],"prefix":"10.3389","volume":"17","author":[{"given":"Nguyen Van","family":"Phuong","sequence":"first","affiliation":[{"name":"Department of Pharmaceutical Sciences, Division of Pharmacology and Toxicology, University of Vienna","place":["Vienna, Austria"]},{"name":"Vienna Doctoral School of Pharmaceutical, Nutritional and Sport Sciences (PhaNuSpo), University of Vienna","place":["Vienna, Austria"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Stary-Weinzinger","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Sciences, Division of Pharmacology and Toxicology, University of Vienna","place":["Vienna, Austria"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,3]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"RP91420","DOI":"10.7554\/elife.91420.4","article-title":"Revealing a hidden conducting state by manipulating the intracellular domains in KV10. 1 exposes the coupling between two gating mechanisms","volume":"12","author":"Abdelaziz","year":"2024","journal-title":"Elife"},{"key":"B2","doi-asserted-by":"publisher","first-page":"6141","DOI":"10.1021\/acs.jcim.3c00943","article-title":"Translocation processes of Pt (II)-based drugs through human breast cancer cell membrane: in silico experiments","volume":"63","author":"Almeida","year":"2023","journal-title":"J.
