【摘要】：目的研究人腦膠質(zhì)瘤中含血小板結(jié)合蛋白基序的解聚素金屬4(ADAMTS4)蛋白酶和ADAMTS5蛋白酶的表達及其與膠質(zhì)瘤病理分級之間的關系。方法采用免疫組化Envision二步法檢測ADAMTS4及ADAMTS5蛋白酶在44例不同級別腦膠質(zhì)瘤、11例瘤周腦組織中的表達,計算陽性細胞百分率,并通過Image Pro Plusversion 6.0(IPP)圖像分析軟件測量計算其平均光密度(MOD)值。結(jié)果 (1)ADAMTS4和ADAMTS5蛋白酶在瘤周腦組織中不表達或極低表達,而在膠質(zhì)瘤組織中高表達,為棕黃色,主要表達定位于細胞外基質(zhì)及細胞質(zhì)中,兩組差異有統(tǒng)計學意義(P0.05)。進一步研究顯示,其蛋白表達量隨著腫瘤級別的升高而升高,WHO分級中低級別、高級別間差異有統(tǒng)計學意義(P0.05)。(2)ADAMTS4與ADAMTS5蛋白酶在膠質(zhì)瘤中表達呈正相關性(χ~2=5.614,r=0.357,P0.05)。結(jié)論(1)ADAMTS4、ADAMTS5蛋白表達量隨著膠質(zhì)瘤級別的升高而升高,提示了ADAMTS4及ADAMTS5蛋白酶在膠質(zhì)瘤的進展、侵襲中發(fā)揮著重要作用。(2)ADAMTS4與ADAMTS5蛋白表達呈正相關性,揭示了在膠質(zhì)瘤的發(fā)生發(fā)展中這兩種蛋白酶可能互相協(xié)同,兩者的過表達共同促進了膠質(zhì)瘤的侵襲。
[Abstract]:Objective to study the expression of depolymerin metallodetrin 4 (ADAMTS4) protease and ADAMTS5 protease in human glioma and their relationship with the pathological grade of human glioma.Methods Immunohistochemical Envision two-step method was used to detect the expression of ADAMTS4 and ADAMTS5 protease in the surrounding brain tissues of 44 patients with different grade gliomas and to calculate the percentage of positive cells.The average optical density (MOD) value was calculated by the Image Pro Plusversion 6.0 image analysis software.Results ADAMTS4 and ADAMTS5 protease were not expressed or very low in the surrounding brain tissue, but were highly expressed in glioma tissues, which were mainly located in extracellular matrix and cytoplasm. The difference between the two groups was statistically significant (P 0.05).Further studies showed that the protein expression level increased with the increase of tumor grade. There was a positive correlation between the high grade ADAMTS4 and the expression of ADAMTS5 protease in gliomas (蠂 ~ 2 ~ 2 / 5.614 ~ 0.357P _ 0.05), and there was a positive correlation between the expression of ADAMTS4 and ADAMTS5 protease in gliomas (蠂 ~ (2 / 2) = 5.614 ~ (0.357) P 0.05).Conclusion ADAMTS4ADAMTS5 protein expression increased with the increase of glioma grade, suggesting that ADAMTS4 and ADAMTS5 protease play an important role in the progression and invasion of glioma. There is a positive correlation between ADAMTS4 and ADAMTS5 protein expression.These two proteases may cooperate with each other in the development of glioma, and their overexpression promotes the invasion of gliomas.
