英文摘要
Objective To detect protein expression of MMPs and TIMPs in various salivary gland neoplasms and to investigate their roles in invasion and metastasis of the malignant salivary gland tumors.Methods Immunohistochemistry and Gelatin zymog- raphy analyses for MMP-2, MMP-9, MT1-MMP, TIMP-1 and TIMP-2 were performed in 26 malignant and 28 benign salivary gland tumors.Results The expression of MMP-2 and MMP-9 was significantly higher in carcinomas than in adenomas(P
