| Research Abstract |
Malignant glioma is the most malignant tumor of the human neoplasms. Despite extensive clinical trials, a good clinical outcome has remained an elusive goal. The success of treatment is hampered by factors such as high degree of infiltration, resistance against irradiation and anti-cancer drugs, and existence of the blood brain barriers that inhibit the drug delivery into the central nervous system. In addition, it has been postulated that immuno-suppressive molecules produced by the tumor cells inhibit the establishment of the anti-tumor immunity such as TGF-β.
In this project, we initially investigated the correlation between the expression of TGF-β and prognosis of the patients with malignant glioma using tissue microarray. However, we failed to show the statistical significance between them. To search for the novel immuno-suppressant produced by the malignant glioma, we investigated the molecules that were specifically expressed by the anaplastic oligodendroglioma, which is malignant but has good prognosis.
Among these molecules, we focused on ABCA2, a membranous protein. Quantitative real-time PCR, immunoblot and immunohistochemical study demonstrated that ABCA2 is highly expressed in oligodendroglial tumors than in astrocytic tumors. Although biological role on the tumor immunology is still under investigation, it is interesting that ABCA2 could serve as a novel tumor marker for oligodendrogliomas.
