KCNA3 and B-cell chronic lymphocytic leukemia: KV1.3 expression is increased in some human malignancies, such as breast and colon cancer (Perez-Verdaguer et al., 2016b) and CLL (Leanza et al., 2013), and KV1.3 inhibition has been shown to induce cell apoptosis (Chandy et al., 2004; Wulff et al., 2009; Teisseyre et al., 2015) and cell proliferation blockage (Cahalan and Chandy, 2009).
