| Outline of Final Research Achievements |
Shn2 KO mice, an animal model of schizophrenia, have been shown to exhibit maturation abnormalities in the granule cells of the hippocampal dentate gyrus (DG), in which the molecular and physiological properties are similar to those of normal immature granule cells. Analysis of several molecular expressions has suggested that maturation abnormalities in the cells emerge during postnatal development.
To find the molecular mechanisms responsible for maturation abnormalities of the cells, we conducted bioinformatics analyses of the microarray data examining the expression changes during postnatal development in the DG of the mutant mice. We used the following bioinformatics tools: NextBio, DAVID (Database for Annotation, Visualization and Integrated Discovery), WGCNA (Weighted gene co-expression network analysis), and CONFAC (Conserved Transcription Factor Biding Site) software. Several signaling pathways were implicated in the emergence of maturation abnormalities in the DG.
