OPN -443C>T Genetic Polymorphism and Tumor OPN Expression are Associated with the Risk and Clinical Features of Papillary Thyroid Cancer in a Chinese Cohort Cell Physiol Biochem 2013;32:171-179 - DOI:10.1159/000350133 Fig. 1. A: No OPN expression in the non-tumor thyroid tissue samples from a patients with thyroiditis. B: Low OPN expression in PTC tumor tissues from a PTC patient with -443 TT genotype. C: High OPN expression in PTC tumor tissues from a PTC patient with -443 TT genotype. © 2013 S. Karger AG, Basel - CC BY-NC 3.0
