12NEUROSURGERY RESEARCHAND EDUCATION FOUNDATION(NREF) AWARD ANDFELLOWSHIP RECIPIENTSThe NREF Research Fellowships and YoungClinician Investigator Awards are madepossible thanks to the generous support ofAANS members, group practices, hospitals,corporate partners and the public. These oneandtwo-year grants truly make a difference tothe scientists receiving them. Typically, theNREF funds 9-12 grants in the area ofbiomaterials, brain tumors, cerebrovasculardisease, endovascular neurosurgery, painmanagement, pediatrics, spine and trauma.2007 Research FellowH. Francis Farhadi,MD, PhDNREF/DePuy SpineResearch FellowUniversity of TexasSponsor: Michael G.Fehlings, MD, PhDProject title: Transcriptional Programming ofthe Myelin Basic Protein Gene FollowingSpinal Cord Injury in the MouseFollowing spinal cord injury (SCI),oligodendrocyte death leads to pronouncedmyelin sheath degradation which precludesrapid and efficient conduction.Demyelination combined with incompleteremyelination have become increasinglyrecognized as prominent components ofsecondary degeneration. To determinewhether the chronic hypomyelination seenreflects a failure of surviving or newly-formedadult oligodendrocytes to recapitulate therobust developmental myelinogenesisprogram, I propose to undertake acomprehensive functional analysis of myelinbasic protein gene regulation followingexperimentally-induced SCI. First, expressionphenotypes of various transgenic linesbearing different combinations of regulatorysequences will be analyzed to determinewhich sequences are sufficient or required forre-expression during the incompleteremyelinative process. Then, a number ofmolecular assays will be employed to identifypotential associated transcription factors andupstream interacting proteins. Candidatemolecules will in turn be tested for theirability to enhance reporter gene expressionlevels in (and remyelination by) transplantedneural stem cells remyelinating the injuredspinal cord.2007 Research FellowAndrew Foy, MDResearch FellowMayo School ofGraduate MedicalEducationSponsor: CynthiaWhetmore, MDProject title: Modulation of Bmil Expressionin Pediatric Medulloblastoma.The proper integration of extrinsic andintrinsic signals is critical for theproliferation and differentiation of neuronalprecursors during normal cerebellardevelopment and the corruption of thesepathways are believed to contribute to thedevelopment of medulloblastoma. Bmi1, amember of the polycomb family ofchromatin remodeling genes, has recentlybeen shown to be involved in theproliferation of granule cell precursorsduring normal cerebellar development. Bmi1is overexpressed in a subset of humanmedulloblastomas and recent studies suggesta link between Bmi1 and sonic hedgehog(Shh) pathway activation. The goal of thepresent proposal is to determine whetherBmi1 is necessary for Shh signal transductionand proliferation in normal and tumorderivedstem cells and whether Bmi1expression is part of the mechanism bywhich stem cells have increasedradioresistance. We will elucidate themechanism of Bmi1 in transduction of Shhsignaling and determine if depletion of Bmi1will inhibit tumor formation in a murinemodel of medulloblastoma. The overall goalof this research is to determine potentialtargets for the development of future therapyfor childhood medulloblastoma.2007 Research FellowJames Frazier, MDNREF/ BiometResearch Fellow JohnsHopkins UniversitySchool of MedicineSponsor: AlfredoQuinones-Hinojosa,MDProject title: Determination of the Role PDGFand EGF in the Migratory Pattern of BrainCancer Stem Cells and Comparison of thisMigratory Pattern to Normal Fetal and AdultHuman Stem Cells in an In Vitro Assay and InVivo Rodent Model using NOD/SCID/IL2rynull Mice.The objective of this research is to studyneural stem cells in the human brain andconsequently the effect that PDGF and EGFhave on the migratory behavior of these stemcells. We will test the hypothesis that humanadult stem cells have the ability to migrateand that their manipulation with PDGF andEGF can change them to a more aggressivemigratory behavior that resembles that ofhigh-grade tumors and/or the fetal humanutilizing both in vitro and in vivo studies.2007 Research FellowJason L. Gerrard,MD, PhDResearch FellowMassachusetts GeneralHospital/HarvardSponsor: Emad N.Eskandar, MDProject title: The role of the PrimateHippocampus and Basal Ganglia Circuits inVisual-Motor Associative Learning.The roles of the basal ganglia in movementplanning and execution and thehippocampus in associational memoryformation are well established. There isincreasing evidence that the basal gangliaalso play a critical role in associative motorlearning. Moreover, there are a number ofknown connections between structureswithin the basal ganglia and thehippocampus.

Tabar, MDProject title: Generation of Purified MotorNeurons from Human Embryonic Stem Cells forCell Therapy in Amyotrophic Lateral Sclerosis.Amyotrophic Lateral Sclerosis (ALS) is adisorder characterized by motorneurondeath. Human embryonic stem (hES) cellscan be differentiated to motorneurons invitro, however such preparations arecontaminated by neural precursors thatproduce tumors in vivo. Our proposalinvolves a genetic modification of hES cellsthat will allow motorneuron purification forgrafting into ALS mice. We propose totransfect hES cells with a bacterial artificialchromosome (BAC) containing themotorneuron-specific HB9 promoter drivingexpression of the green fluorescent protein,thereby fluorescently labeling motorneurons.Motorneurons will be purified withfluorescence-activated cell sorting andtransplanted into the spinal cord of ALS mice.2007 Research FellowUzma Samadani,MD, PhDACS/AANS-NREFFaculty CareerDevelopment AwardNew York UniversityMedical CenterSponsor: Howard L. Weiner, MDProject title: Sonic Hedgehog Therapy AfterLysis of Intracerebral Hemmorhage.Intracranial hemorrhages result in highmorbidity and mortality through severalmechanisms including disruption ofadjacent white matter tracts. Repair of thesetracts may be possible through recruitmentof neural progenitor cells induced toproliferate, differentiate and function by amyriad of signal transduction molecules. Wecompare the baseline endogenoussubventricular zone stem cell division rate,with the rate seen after induced intracranialhemorrhage and pretreatment with the smallmolecule sonic hedgehog. The utilization ofsmall molecule therapy to promoterestoration of neurologic function afterhemorrhage ultimately has implications forthe treatment of deficits caused by othermechanisms including stroke and trauma.2008 Research FellowRahul Jandial, MDNREF/AANS PinnaclePartners ResearchFellow University ofCalifornia – San DiegoSponsor: AlexyTerskikh, PhDProject title: Role of MELK in Self-Renewal ofNeural Progenitors.Stem/precursor cells hold great promise forcell replacement therapies and regenerativemedicine, but their clinical success willdepend on our ability to control their selfrenewaland differentiation. MELK is a genethat may modulate proliferation in neuralprecursors and is found in the subventricularzone of MELK-EGFP promoter-reportertransgenic mice.We intend to investigate the molecularmechanisms that regulate neural stem cellproliferation and self-renewal. To do this wewill evaluate the proliferative capacity andcell fate of MELK/EGFP-positive cellsisolated from our transgenic animals viatransplantation assays and determine if thesecells from the neonatal pup subventricularzone are proliferating neural precursors invivo. Subsequently these cells will beevaluated in vitro with siRNA and cDNAs forassessment of proliferative capacity atvariable levels of MELK gene product, as wellas investigate the involvement of putativeMELK targets and their effects onproliferation and self-renewal.By understanding self-renewal and the roleMELK plays, we would provide avenues forpotential modulation of neurogenesisdependent on MELK expression. Further,synthetic agonists of MELK could be used tomodulate the amplification of neuralprogenitors for clinical application.2008 Research FellowJason Weinstein, MDNREF/CodmanResearch FellowOregon Health andScience UniversitySponsor: EdwardNeuwelt, MDProject title: Optimization of N-acetylcysteine(NAC) Administration for Neuroprotection inan Experimental Rat CNS Injury Model andInvestigations into the Pathophysiology ofPosttraumatic Hydrocephalus (PTH).Traumatic brain injury (TBI) remains amajor source of morbidity and mortalitywith 1.5 million sustaining TBI each year; ofthese, 80-90,000 experience long-termdisability (CDC 2001). There are currentlyno effective pharmacological agents used inclinical practice that reduce secondary braininjury. Additionally, hydrocephalus occurs in20% of these patients and is associated withpoor outcome (Marmarou 1996). Themechanism for posttraumatic hydrocephalusformation is incompletely understood, butlikely involves fibrosis of the pathways ofcerebrospinal fluid (CSF) absorption:cervical lymphatics and arachnoidgranulations. Fibrosis following TBI may bedue to induction of connective tissue growthfactor (CTGF) which is, in turn, regulated byreactive oxygen species (ROS). One of thephysiological defense mechanisms againstoxidative stress involves removal of freeradicals by the tripeptide glutathione (GSH),formed by three amino acids: glutamate,glycine, and cysteine. N-acetylcysteine (NAC),a thiol containing molecule, has both directanti-oxidant activity and serves as a precursorfor GSH biosynthesis. The followingexperimental design is intended to optimizeadministration of NAC for neuroprotectionin an experimental rat TBI model, providenovel insight into the mechanism andprevention of posttraumatic hydrocephalus,and, if successful, will lead directly to clinicaltrials of NAC in human TBI.www.AANS.orgIntroduction, Awards and Lectures

15The goal of this project is to develop a betterunderstanding of the electrophysiologicalchanges that occur after mild traumatic braininjury (mTBI). We plan to use a closed headinjury model in rats to test the hypothesisthat the functional deficits after mTBI: (1)are associated with characteristicelectrophysiological changes in specific areasof the brain; (2) may be identified usingnoninvasive methods such as EEG; and (3)may be reversed to some degree by means ofhigh-frequency field stimulation using astereotactically implanted electrode. Thisinformation should assist in the design ofnovel strategies for diagnosis and treatment.William P. Van Wagenen FellowshipThe William P.
