title: The expression of ATF3, MMP-2 and maspin in tissue chip of glioma.
abstract: This paper tested and analyzed the expression of ATF3 (activating transcription factor), MMP-2 (matrix metalloprotease) and maspin in tissue chip of glioma and its correlation with glioma advancement. Based on immunohistochemical staining, this paper selected 100 patients with glioma and 13 healthy persons to test the relative expression of ATF3, MMP-2 and maspin. The result witnessed 72.0% of ATF3 expression in glioma and 15.4% in healthy brain tissues with P<0.05; glioma had 76.0% of MMP-2 expression while healthy brain tissues only had 7.7% (P<0.05); but maspin expression with 53.0% in glioma was much lower than that with 100% in healthy tissues with P<0.05. If the pathological stage of glioma rose up, the expression of ATF3 and MMP-2 accordingly increased while maspin expression decreased. The correlation between ATF3 expression and MMP-2 expression was positive with r=0.553 and p<0.01; negative correlation between ATF3 expression and maspin expression was found with r=-0.457 and p<0.01; and the expression of MMP-2 and maspin were negatively related with r=-0.551 and p<0.01. According to the above results, it could be concluded that the expression of ATF3, MMP-2 and maspin did relate with each other. Besides, the high expression of ATF3 and MMP-2 as well as the low expression of maspin had great influence on glioma, playing a key role in glioma's occurrence, advancement, invasion and metastasis.
