| Outline of Final Research Achievements |
This study aimed to clarify the molecular mechanism of transgenerational epigenetic inheritance. The miRNAs upregulated in the culture medium of pancreatic beta cell line were consistent with the miRNA species upregulated in the blood of diabetic mice. This suggests that miRNAs produced in degenerating beta cells should enter blood stream and have an influence on the germ cells. The methylated DNA regions of diabetic mice sperm in the previous report were not consistent with our result using our inbred strain of mice. Then, we revealed the epigenomic profile in glycometabolic genes using our own mice.
