AbstractBackground and Study Aims
Thioredoxin reductase (TrxR) is a redox protein that is considered to play a role in tumor progression. The purpose of this study was to assess the expression of TrxR in blood and tumor samples of glioblastoma multiforme (GBM) patients.Patients
TrxR levels were evaluated in blood and GBM tissues extracted from 27 patients, in normal brain tissues of 12 autopsy cases, and in blood samples of 12 healthy subjects. The results were compared between tumor and control groups.Results
The mean level of TrxR in GBM tissues (74.5 ± 14.9 U/g wet tissue) was remarkably higher than in normal brain tissues (14.8 ± 3.4 U/g wet tissue). The mean TrxR levels in blood were significantly higher in GBM patients (296.3 ± 43.6 U/mL) than in the controls (203.0 ± 11.3 U/mL).Conclusions
These findings suggest that high levels of TrxR may be related to progression of GBM.
