ABSTRACT
<p><b>OBJECTIVE</b>To investigate the expression level of inhibitor of apoptosis protein survivin gene in human brain glioma and its role in malignant proliferation and antiapoptosis of brain glioma.</p><p><b>METHODS</b>Eighty-three cases of brain glioma specimen was chosen, protein expression of survivin and proliferating cell nuclear antigen (PCNA) was investigated by immunohistochemistry streptavidin-biotin complex (SABC) method, the immunoreactivity score (IRS) of survivin and the proliferative index (PI) were counted. Apoptotic cells were screened by TdT-mediated dUTP-biotin nick-end labeling (TUNEL) method, and the apoptotic index (AI) of brain glioma was calculated.</p><p><b>RESULTS</b>The survivin IRS, PI and AI of brain glioma were 3.8 +/- 3.9, (28.4 +/- 19.5)% and (1.0 +/- 0.8)% respectively, and all of them were elevated with the increase of pathological grade of brain glioma (P < 0.01 for all). PI in survivin positive group was significantly higher than that in survivin negative group (P < 0.01), and PI was positively correlated with survivin IRS (r = 0.740, P < 0.01). There was no significant difference between AI in survivin positive group and that in survivin negative group (P > 0.05), however, AI was negatively correlated with survivin IRS (r = -0.307, P < 0.01).</p><p><b>CONCLUSIONS</b>Survivin is overexpressed in brain glioma, and which may play important roles in malignant proliferation and antiapoptosis of brain glioma.</p>
