Epilepsia 49:50-4. 2008..Future studies need to focus on how these changes in neurogenesis influence dentate gyrus function and what they imply for epileptogenesis and learning and memory impairments, so commonly found in children with temporal lobe epilepsy... - The role of transcription factors cyclic-AMP responsive element modulator (CREM) and inducible cyclic-AMP early repressor (ICER) in epileptogenesisB E Porter
Department of Pediatrics, The Children Hospital of Philadelphia at the University of Pennsylvania, 502C Abramson, 3516 Civic Center Boulevard, Philadelphia, PA 19104, USA

Research Grants
- Neurogenesis in Pediatric Temporal Lobe EpilepsyBRENDA PORTER; Fiscal Year: 2007..The studies proposed will take place in the laboratories of Drs. Douglas Coulter and Amy Brooks-Kayal, at The Children's Hospital of Philadelphia. This Award will facilitate my goal of a career in academic medicine. ..
- CRE Mediated Transcription in EpileptogenesisBrenda E Porter; Fiscal Year: 2010..We will determine if blocking the increase in the regulatory proteins protects the animals from the development of epilepsy. In addition we will determine which genes these proteins regulate in epilepsy. ..
