Outline of Final Research Achievements

Epigenome of spermatogenic cells around Alzheimer related genes in mice, changed under the low gravity environment, was not consistent with that of the brain. However, it was quite intriguing that epigenome of the brain was changed under low gravity, almost the same gravity in Mars. This study also aimed to investigate how epigenomic changes by low gravity in spermatogenic cells inherit to the offsprings. Therefore, we developed the study model, in which the epigenome of germ cells correlate with mRNA expression in somatic cells. The epigenome of germ cells and pancreatic islet cells correlate in insulin related genes, and with exosomal RNAs circulating in the blood. Here, establishment of embryonic stem cells from the blastocysts derived from type II diabetic males.
