Disturbances of Kynurenine Pathway of Trytophan Metabolism in Schizophrenia: A Quantitative Reverse Transcription Polymerase Chain Reaction (RT-PCR) Study
NCT00573300 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 60
Last updated 2009-08-12
Summary
In this pilot study, the investigators propose to characterize the pattern of activation of the kynurenine pathway of tryptophan metabolism in peripheral macrophages of patients with schizophrenia. To do this, the investigators will measure the gene expression of several major enzymes in this pathway in macrophages, including the key enzyme involved in tryptophan to kynurenine metabolism, IDO, by means of quantitative reverse-transcription polymerase chain reaction (RT-PCR). The focus on enzyme mRNA expression as opposed to serum or cerebrospinal fluid levels of metabolites provides a possibly more sensitive characterization of the activation of this metabolic pathway.
