| Outline of Final Research Achievements |
We studied male and female senescence marker protein-30 (SMP30)/ gluconolactonase (GNL) knockout (KO) mice, totally lacks the ability to synthesize vitamin C similar to a comparable deficit seen in humans, in several behavioral paradigms designed to evaluate anxiety and depression in terms of the impact vitamin C has on mental health. Two environments were established based on hierarchical social relations of stable or unstable housing’s susceptibility to anxiety- and depressive-like behaviors.
Vitamin C deficiency developed anxiety- and depression-like behaviors. When comparing stable vs. unstable social conditions, results showed that males have a low tolerance for novel / inescapable events, whereas females are more vulnerable to habitual / inescapable situations. We found that socially unstable subjects showed significantly lower GSH levels than the stable group.
These results revealed a fact that vitamin C is important for preventing psychiatric disorders.
