Research in the Neuro-Oncology division focuses on the treatment of primary brain tumors. Faculty members are engaged in a number of clinical trials and leading collaborative lab-based research involving novel treatment modalities and cellular responses to therapeutics. The close collaboration between clinical and basic science investigations fosters translational research and thus results in cutting edge patient care.
Faculty members in the Neuro-Oncology Division are leading research in the following areas:
Dr. Moots’ research activities focus on chemotherapy trials for patients with primary CNS neoplasms. He leads ongoing trials for recurrent anaplastic astrocytoma, IDH mutated gliomas, and progressive plexiform neurofibromas in patient with NF1. Prior trials have included various newly diagnosed gliomas, medulloblastoma, ependymoma, CNS lymphoma and carcinomatous meningitis. He was the study chair for an ECOG adult medulloblastoma trial.
Dr. Clark’s research focuses on clinical trial development and translational work for tumors of the CNS including glioblastoma, anaplastic glioma, low-grade glioma, meningioma. He recently completed a phase I trial of epigenetic modification in recurrent glioblastoma. This clinical trial included laboratory investigations of tumor DNA methylation patterns before and after treatment. Dr. Clark has laboratory projects assessing DNA methylation patterns and their changes and response to chemotherapy in glioblastoma model systems using zebrafish implants and organoid cultures.
Brain Tumor Stem Cells
Dr. Cooper’s research interests involve brain tumor stem cells and the development of new antibodies to recognize glioma cells. The Cooper laboratory studies brain tumor cellular heterogeneity with respect to molecular pathways that drive glioma cell growth and adaptive responses to therapeutic modalities. Towards these goals, the laboratory utilizes a patient tissue repository to identify the specific glioma subtypes in which the Hedgehog signaling pathway is operational and activated. Dr. Cooper’s research team has established a preclinical model for growing human malignant gliomas in mice to demonstrate that Hedgehog signaling regulates glioma growth and that pathway inhibition enhances survival. The Hh pathway appears to be activated in a subset of glioma cells (CD133+ cells), and determining how Hh signaling impacts this cellular compartment in gliomas is a primary focus of research. Longer term goals of these preclinical studies are to design clinical trials of Hedgehog inhibitors based upon selecting patients with malignant glioma who might best respond to Hedgehog inhibitors, defining the mechanism of action of Hedgehog pathway inhibition on glioma cancer stem cells and avoiding potential mechanisms of drug resistance.
