Survival data and expression levels of GGT7 in GBM patients. (A) Patients were separated by relative expression of GGT7. Statistical significance was determined using log-rank test. (B) Expression of GGT7 using the R2 microarray analysis and visualization platform (http://r2.amc.nl). Normal brain samples consisted of 173 tissue samples, GBM cell samples consisted of 84 cell lines derived from GBM patients, and the primary GBM samples consisted of 101 primary GBM tissue samples. *-denotes a sample that resided outside the 95% confidence interval. (C) Western blot analyzing GGT7 expression in eight primary GBM tissue samples and two normal brain samples. GAPDH was used as a protein load control. Fold difference is represented below each blot.
