KCNA3 and benign neoplasm: We observed that the Kv1.3 levels in mTTs were significantly higher as compared to cells isolated from healthy patients or benign tumor patients (whole-cell conductance values were 2.63 ± 0.88 nS for healthy T cells (hTs) (5 donors, N = 29), 5.33 ± 0.76 nS for mTTs (4 patients, N = 23), 2.46 ± 0.6 nS for bTTs (3 patients, N = 22), p values were 0.035 for hTs vs. mTTs and 0.0016 for mTTs vs. bTTs).
