- Abstract
- PURPOSE: Frozen tumor tissues from a patient who showed rapid progression to anaplastic oligodendroglioma after near total resection of oligodendroglioma were used to examine differential expression of proteins to gain better understanding of the pathogenesis of malignant transformation. METHODS: We have determined their protein profiles using a 2D gel electrophoresis and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry approach. RESULTS: Among 23 differentially expressed spots, overexpression of peroxiredoxin 6 and underexpression of rho GDP dissociation inhibitor alpha were confirmed to be valid after western blot and immunocytochemical analysis of oligodendroglioma tissue. CONCLUSIONS: Abnormal expression of peroxiredoxin 6 and rho GDP dissociation inhibitor alpha may be associated with malignant transformation in oligodendroglioma and these proteins might be candidates of molecular predictive factors.
