Raw uptake value of (A-B) 125I-, (C) 99mTcO4-, or (D) B18F4- in the absence or presence of 50 μM perchlorate (ClO4) in transfected or transduced cells. (E-H) Uptake of each radioisotope normalized to hNIS uptake via cell surface protein expression. (I-L) The percentage of maximum 125I- uptake activity (uptake at 0 μM ClO4) maintained in the presence of 50 μM perchlorate (ClO4). Values are averages of triplicate assays with standard deviation. n.s. indicates not significant; * indicates p < 0.05; ** indicates p < 0.01; *** indicates p < 0.001; **** indicates p < 0.0001; Untrans. = untransfected or untransduced.
