Expression data from brain tissue of Rattus norvegicus treated with D-Serine


ABSTRACT: d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored. Affymetrix microarray technology was used to determine differential gene expression resulting from D-Serine exposure. Keywords: Dose course Male Fisher 344 rats aged 11-12 weeks were treated with various doses (0, 5, 20, 50, 200 and 500 mg/kg) of d-serine and terminally sacrificed 96 hours post-exposure. An approximate 30mg-section of the forebrain was processed for total RNA isolation.

D-Serine, an endogenous amino acid, is involved in many physiological processes through its interaction with the glycine binding site of the N-methyl-D-aspartate (NMDA) receptor. It has important roles in development, learning, and cell death signaling. Recent evidence suggests that decreased function of the NMDA receptor is related to the etiology of schizophrenia, and the use of D-serine as add-on therapy is beneficial in alleviating the symptoms of treatment-refractory schizophrenia. The NMDA  ...[more]
