In our analysis, several genes coding for Ca2+ and K+ channels were altered in CSC-like subpopulation like KCNMA1, previously described in prostate cancer [95] and in breast cancer [96], [97], and CACN1AG also altered in gastric cancers, colorectal cancers and acute myeloid leukemia (AML) [98]. The gene discussed is KCNMA1; the disease is breast cancer.
