| 1 | Correlation of matrix metalloproteinase-2, -9, tissue inhibitor-1 of matrix metalloproteinase and CD44 variant 6 in head and neck cancer metastasis显示文摘This study aimed to explore the molecular mechanism in tumor invasion and metastasis. The ex-pression of matrix metalloproteinase-2,-9 (MMP-2,MMP-9), tissue inhibitor-1 of matrix metalloprote inase(TIMP-1) , cell adhesion molecule 44 variant 6 (CD44v6) , HER2/neu and p53 was investigated in 154 pa-tients with head and neck squamous cell carcinoma (SCC) by ABC and ImmunoMax immunohistochemical method. Their clinical relevance and correlation were analysed. The expression of MMP-2, MMP-9, TIMP-1,CD44v6, HER2/neu and p53 was found in cancer cells in 87.01%, 85.71%, 68. 18%, 98.05%,55.19% and 50.65% cases respectively. Linear regression and correlation analysis revealed that there wasclose positive relationship ( P < 0.05) between the expression of MMP-2 and MMP-9, TIMP-1 and CD44v6,HER2/neu and MMP-9, MMP-2 and p53. Up-regulation of MMP-2 was accompanied by advanced T stage( P < 0.01 ) . There was also a trend of MMP-2 expression being related with tumor metastasis. Increased ex-pression of HER2/neu was found in patients with tumor recurrence( P < 0.05 ) . The expression of TIMP-1 washigher in laryngeal cancer than that in pharyngeal cancer, and higher in keratinizing and non-keratlnizing SCC than that in basaloid SCC ( P < 0.05 ) . These findings suggested that MMP-2 and MMP-9, HER2/neu andMMP-9, MMP-2 and p53 had a coordinate function in aggression of tumor; that MMP-2 had a more important function than MMP-9 in tumor invasion and metastasis; and that HER2/neu might serve as a biomarker forpoor prognosis in HNSCC. | 徐娅苹 赵学群 SOMMER,K.
