TNFAIP2 expression was up-regulated in 81 glioma tissues and 5 glioma cells. A. shows that the expression levels of TNFAIP2 in 81 human glioma tissues were higher than in 5 non-cancerous brain tissues normalized to GAPDH. TNFAIP2 expression was higher in high-grade gliomas (WHO grades III and IV) than in low-grade gliomas (WHO grades I and II). B. shows that the expression levels of TNFAIP2 mRNA in 5 glioma cell-lines were higher than in5 non-cancerous brain tissues. C. The left panel shows the Western blot results, which further confirmed that the expression level of TNFAIP2 protein was higher in glioma cell-lines than in normal human astrocyte 1800 cells. The right panel shows the relative expression of TNFAIP2 protein in glioma cells, as depicted in the histogram. Data are shown as mean + s.d. (n = 3); *indicates P-value <0.05, **indicates P-value <0.01.
