Outline of Final Research Achievements |
The treatment for schizophrenia has improved, but there are some symptoms which do not improve entirely. The cause of illness remains being unexplained. If the etiology of schizophrenia is elucidated, a treatment and the prophylaxis of schizophrenia will progress. There are various hypotheses, but we hypothesized that the L-serine synthesis pathway might be related with a disease, so we investigated the L-serine synthesis pathway system in the patients. As a result, we found synthetic ability of the synthetases of L-serine increasing in the patients. In addition, we found that quantities of the mRNA expression of the enzymes which synthesize L-serine were decreased in the patients. However, as a whole, the association between such change and blood concentration of L-serine was not found. In future, we are going to investigate the relationship between L-serine synthesis pathway and the blood concentration of L-serine or amino acids related to L-serine.
