Outline of Final Research Achievements

Neonatal exposure of DES induced persistent hyperplasia of epithelial cells in the vagina of mice. In this study, we showed that inflammatory transcription factor is likely to be activated by neonatally DES exposure, suggesting that DES-dependent hyperplasia may be associated with inflammatory reactions. In addition, CAGE (Cap Analysis of Gene Expression) analysis revealed that increased expression of certain non-coding RNAs was observed by the DES-exposure at the neonatal stage of mice.
