摘要: Glioblastoma (GBM) is the most common malignant brain tumor in adults. We designed an adeno-associated virus (AAV) vector for intracranial delivery of secreted HSP70-targeted peptide APOPTIN derived from Apoptin to GBM tumors. applied this therapy models using human U87MG glioma cells and xenograft mice. In U251MG cells, conditioned medium AAV2-apoptin-derived (ADP)-expressing induced 83% 78% cell death. mice bearing tumors treated with AAV2-ADP, treatment resulted a significant decrease growth longer survival orthotopic invasive These data indicate that ssAAV2-ADP injection left hemisphere effectively prevented ipsilateral but was insufficient prevent distal contralateral hemisphere. However, systemic route effective approach treating widely dispersed summary, AAV2-ADP attractive treatment.
