ABSTRACT
The expressions of matrix metalloproteinnse-9 (MMP-9), tissue inhibitor of metalloproteinase-1 (TIMP-1) ,and NF-κB in 157 cases of papillary thyroid cancer and 30 cases of papillary thyroid tumors were detected by immunohistochemistry and in situ hybridization. The expressions of MMP-9 and NF-κB protein and mRNA in papillary thyroid cancers were significantly higher than those in benign tumors (all P <0.01), and increased according to the pathological grading (P<0.01). The expressions of MMP-9 and NF-κB protein and mRNA in papillary thyroid cancers with cervical lymph node metastasis were higher than those without metastasis (both P <0.01). The expressions of TIMP-1 protein and mRNA appeared an opposite direction of MMP-9 expression.
