Western blot analyses of PLZF in normal thyroid, adenomatous lesion (A), and papillary thyroid carcinoma (B) samples. For immunoblotting, an aliquot (10 μg protein) of each lysate was loaded. To compare the PLZF expression levels among different membranes, we used the PLZF/β-actin expression ratios, representing the densitometrically analysed data for each membrane divided by the mean value for normal thyroid tissues, which was used as an internal control (C). *p < 0.05, vs. normal thyroid and papillary thyroid carcinoma; **p < 0.05, vs. adenomatous lesion and papillary thyroid carcinoma.
