| Outline of Final Research Achievements |
AGXT2(alanine: glyoxylate aminotransferase 2) is an aminotransferase that degrades not only a D-3-aminoisobutyrate, a middle product of thymine degradation, but also an asymmetric dimethylarginine that inhibits nitric oxide production. One third of Japanese lack AGXT2 activity and the activity is distributed in brain as well as liver and kidney. In this study, we indicated 1) distribution of Agxt2 gene products in the rat brain, 2)genetic mechanism that four functional SNPs in the AGXT2 gene are related to its activity, 3)no association between the AGXT2 gene and schizophrenia, and 4)positive association between the AGXT2 gene and carotid Intima-Media Thickness, which is related to hypertension, in Japanese subjects. We suggest that the functional SNPs of the AGXT2 gene are not related to functional psychoses but related to vascular brain diseases, such as vascular dementia.
