Together with the electrophysiological findings showing that the intrinsic properties, such as voltage-dependent activation and inactivation of Nav1.8 sodium channels, remained unchanged after the inoculation of tumor cells, the increased expression of Nav1.8 on the cell membrane provides a possible explanation for the enhanced density of Nav1.8- mediated sodium current in the DRG neurons of MRMT-1-treated rats, which actually represents the functional upregulation of Nav1.8 sodium channels in the DRG neurons of bone cancer rats. Here, SCN10A is linked to bone cancer.
