Treatment of Glioblastoma Intracranial Xenografts by Notch Inhibition

There is emerging evidence showing that a small population of cancer stem cells within brain tumors, including glioblastomas, are responsible for tumor formation and ongoing tumor growth. The Notch Signaling Pathway is important for cell to cell communication, which involves genetic regulation mechanisms that control multiple cell growth during embryonic and adult life. It has been shown that the Notch Signaling Pathway regulates normal stem cells in the central nervous system.

Notch signaling for some reason malfunctions in many cancers. This study hypothesizes that a combination of inhibitors of Notch signaling and radiation therapy will enhance the depletion of cancer stem cells, and improve the treatment of glioblastoma.

Update, 2009

Dr. Fan reports that the project is on schedule and the lab has finished the Notch inhibitor treatment in GBM intracranial xenografts and combination with down stream target Akt inhibitor treatment in vitro. They are currently working on combination treatment in vivo.

He has found notch inhibition prevents GBM neurosphere growth in vitro and propagation in vivo. So far, there have been no unexpected results and Dr. Fan plans to publish the study's results in a scientific peer-reviewed journal.
