To evaluate the associations of phosphorylated c-Jun NH2-terminal kinase (p-JNK) expression with clinicopathological features in patients with papillary thyroid carcinoma, p-JNK expression were immunohistochemically measured in 121 thyroid samples. p-JNK was overexpressed in papillary thyroid carcinomas with respect to matched nontumorous tissues (P=0.000), which was supported by western blot analysis. Increased p-JNK expression was significantly associated with the presence of lymph node metastases...
