Medulloblastoma (MB) patients suffer a poor prognosis and limitations of current treatments necessitate development of targeted therapies. TRAIL, a pro-apoptotic protein, targets tumor cells while sparing normal cells; however some tumors remain resistant, including the MB cell line DAOY. Mesenchymal stem cells (MSC) have been used for their tumoritropic properties to deliver apoptotic proteins. In this study, a TRAIL-expressing MSC line was investigated for a therapeutic effect on DAOYs in vitro, in the presence or absence of HDAC inhibitor MS-275. Results indicate that DAOYs respond to secreted TRAIL, and that MS-275 enhances this effect. Bioluminescent imaging shows that DAOYs survive and grow in an intracranial xenograft mouse model, allowing for future in vivo studies.
