NaV1.5 voltage-gated sodium channels are abnormally expressed in breast tumours and their expression level is associated with metastatic occurrence and patients’ death. In breast cancer cells, NaV1.5 activity promotes the proteolytic degradation of the extracellular matrix and enhances cell invasiveness. In this study, we showed that the extinction of(More)
The development of metastases largely relies on the capacity of cancer cells to invade extracellular matrices (ECM) using two invasion modes termed 'mesenchymal' and 'amoeboid', with possible transitions between these modes. Here we show that the SCN4B gene, encoding for the β4 protein, initially characterized as an auxiliary subunit of voltage-gated sodium(More)
