Survival analysis of ion channels interacting with EMT-related genes showed KCNN4 (p-value: 0.071), CFTR (p-value: 0.16), KCNJ10 (p-value: 0.17), VDAC1 (p-value: 0.000003) and VDAC2 (p-value: 0.052) (Figure S5F–J) the level of expression associated with survival of breast cancer patients. This evidence concerns the gene KCNN4 and breast cancer.
