【摘要】 目的研究粘着斑激酶(focal adhesion kinase,FAK)和基质金属蛋白酶-9(matrix metalloproteinase,MMP-9)在垂体腺瘤中的表达及意义。方法垂体腺瘤组织标本5O例,其中侵袭性27例,非侵袭性23例,利用免疫组化法检测并分析比较FAK及MMP-9在侵袭性垂体腺瘤和非侵袭性垂体腺瘤中的表达。结果侵袭性垂体腺瘤中FAK和MMP-9的表达均高于非侵袭性垂体腺瘤(P<0.05);在侵袭性垂体腺瘤中FAK和MMP-9的表达水平呈正相关(P<0.05)。结论垂体腺瘤的侵袭性与FAK、MMP-9的过度表达有关,FAK和MMP-9可作为辅助诊断侵袭性垂体腺瘤的一项生物学指标。更多还原

【Abstract】 ObjectiveTo explore the expressions of focal adhesion kinase(FAK) and matrix metalloproteinase(MMP-9) in the pituitary adenomas .MethodsThe expressions of FAK and MMP-9 were determined by immunohisto- chemical technique in 50 pituitary adenoma tissues samples obtained by surgery,including 27 invasive pituitary adenomas and 23 non-invasive pituitary adenomas.The relationships of FAK and MMP-9 expressions with tumor invasiveness and the relationship among FAK and MMP-9 expressions in invasive pituitary adenomas were analysed.ResultsThe expressions of FAK and MMP-9 in the invasive pituitary adenomas are significantly higher than those in the non-invasive pituitary adenomas(P<0.05).The expression of FAK was positively related to that of MMP-9 in the invasive pituitary adenomas (P<0.05).ConclusionsThere was a significant correlation between invasive characters of pituitary adenomas and the over expression of FAK and MMP-9.It is suggested that the determination of expression levels of FAK and MMP-9 may be helpful to diagnosing invasive pituitary adenomas.更多还原
