Analysis of the Cancer Genome Atlas Data to Determine the Prognostic Value of GABPB1L and TERT in Glioblastoma

Abstract

Glioblastoma multiforme (GBM) is the most lethal type of brain tumor and its prognosis was extremely poor. Here, we studied the clinical and prognostic value of telomerase reverse transcriptase (TERT) and GA Binding Protein Transcription Factor Subunit Beta 1 longer (GABPB1L) mRNA expression in GBM by using open big data. In total 152 GBM patients, gene expressions were downloaded from the Cancer Genome Atlas (TCGA) data and its values were statistically analyzed. TCGA data showed that GABPB1L mRNA expression levels did not correlate with those of TERT mRNA (r = -0.027, p = 0.744). GABPB1L and TERT expressions in GBM were associated with subtype by gene expression. GABPB1L (562.7 ± 76.8 days vs. 479.1 ± 5.8 days, p = 0.401) and TERT (468.1 ± 43.6 days vs. 565.3 ± 75.8 days, p = 0.403) expression was not associated with GBM prognosis. However, disease-free survival was tended to be different in GBM patients according to TERT and GABPB1L expressions though it did not get statistical significance (2122.6 ± 160.2 days vs. 1381.1 ± 244.0 days, p = 0.072). These genes may contribute to the GBM pathogenesis and its further study should be performed in GBM patients and cell lines.
