Expression and prognostic value of TCTN1 in GBMs of the Rembrandt cohort. (A) TCTN1 gene has significantly higher expression in GBM samples in comparison to non-tumor controls. P value was calculated by Student's t-test. (B) Kaplan-Meier curve was plotted according to different TCTN1 gene expression for overall survival of GBM patients. P values were obtained from log-rank test, while hazard ratio (HR) and 95% confidence interval (CI) were determined by univariate Cox regression model.
