A Potassium Channel Makes Cancer Cells Easier to Break
Activating KCNMB1 stiffened metastatic cells and helped immune cells attack them in preclinical models.
Summary
Activating KCNMB1 stiffened metastatic cells and helped immune cells attack them in preclinical models.
University of Illinois Chicago researchers identified the ion-channel protein KCNMB1 as a controller of cancer-cell stiffness. Increasing its activity made metastatic cells less yielding and more vulnerable to T cells and natural killer cells. In a metastatic breast-cancer animal model, the potassium-channel activator BMS-204352 reduced distant lung growth, with effects dependent on functional T cells. The work suggests a druggable biophysical target but has not established safety or benefit in patients.
Why it matters
