| Outline of Final Research Achievements |
Using poly (I:C) mouse model, we analyzed fetal neural progenitor cells. RNA-seq analysis revealed increased expression of immune response and inflammation-related genes and decreased expression of genes related to neurodevelopment. Protein analysis by iTRAQ showed increased expression of factors suppressing viral activity. In addition, analysis of the cytosine modification status for each of the three active LINE-1 subfamilies in mice identified subfamily dependent epigenetic changes. One subfamily showed decreased cytosine methylation and increased hydroxymethylation, suggesting the possibility of selective activation of retrotransposition activity.
