Bioelectrical signature of cancer cells

The bioelectrical signature of cancer cells refers to the characteristic electrical state of malignant cells, most notably a significantly depolarized resting membrane potential (Vmem) compared to quiescent, differentiated cells (Yang & Brackenbury, 2013). This signature is generated by the dysregulated expression and activity of various ion channels, pumps, and transporters, which create a distinct bioelectric code that drives tumor progression (Levin, 2021). These electrical properties are not merely byproducts of the cancerous state but act as functional regulators of cell proliferation, migration, and the epithelial-to-mesenchymal transition (Prevarskaya et al., 2018). For instance, voltage-gated sodium channels (VGSCs) are often upregulated in metastatic cells, where they enhance invasive capacity (Djamgoz et al., 2019). Therapeutic strategies targeting this signature involve using ion channel drugs to repolarize the membrane or block specific channels, thereby inhibiting the metastatic cascade and potentially sensitizing cells to traditional chemotherapy (Djamgoz et al., 2019). This approach, often termed bioelectric therapy, seeks to normalize the cellular electrical environment to revert or halt the malignant phenotype. Because these signatures are often specific to certain stages of cancer, they also serve as potential diagnostic and prognostic biomarkers.
