Figure 4From: Influence of dietary iodine deficiency on the thyroid gland in Slc26a4-null mutant mice Effect of iodine deficiency on serum total thyroxine (TT4) levels in Slc26a4-/- and Slc26a4+/- mice. A, TT4 levels of Slc26a4-/- mice among control chow (CCD) and iodine-deficient chow (ICD) groups. B, TT4 levels of Slc26a4+/- mice among CCD and ICD groups. Mann-Whitney U-testing indicated significant differences for both comparisons.Back to article page
