INTRODUCTION: Atypical teratoid rhabdoid tumors (ATRTs) are molecularly-defined by deletions or mutations in tumor suppressor INI1. INI1 deficiency causes dysfunction of chromatin-remodeling complexes which normally oppose EZH2, a epigenetic gene silencing protein. In the setting deficiency, EZH2 is over-expressed, leading to ATRT oncogenesis. Using novel patient-derived orthotopic xenograft (PDOX) models, we investigated pre-clinical utility therapeutic inhibition using drug DZNep. METHODS:...

Accumulating evidences suggest that recurrent tumors may acquire genetic abnormalities different from their treatment naive counterparts. Since surgery is rarely an option for terminal brain tumors, autopsy frequently the only chance to obtain therapy resistant tumor tissues. To determine and if (some) cells can survival postmortem anoxia/starvation identify seed repopulate orthotopic xenograft we collected 29 autopsied including 15 DIPGs, 7 GBMs, 4 medulloblastomas (MB), 2 ependymomas 1...

INTRODUCTION: Recent genomic studies have provided significant insight into the pathogenesis of pediatric central nervous system (CNS) tumors. However, little is known about genetic events underlying rare CNS tumor types, which often present diagnostic and therapeutic challenges. The BASIC3 clinical exome sequencing study children with newly-diagnosed tumors offers an opportunity to investigate basis these METHODS: Tumor germline whole (WES) performed in a CLIA-certified laboratory on...
