Shear sensitivity of hERG mutants. A, scatter plot shows response of N33T mutant to shear stress (mean ± S.D., p < 0.05, n = 7, paired t test). B, scatter plot shows response of R56Q mutant to shear stress (mean ± S.D., p > 0.05, n = 7, paired t test). C, scatter plot shows response of N588K mutant to shear stress. Both step (mean ± S.D., p < 0.001, n = 7, paired t test) and tail current (mean ± S.D., p < 0.001, n = 7, paired t test) showed significant increase in current during shear stress. ns, non-significant.
