| Research Abstract |
Changes in women’s life styles have lead to the tendency of late childbearing, requiring ART at later ages. However, oxidative stress and decreased mitochondrial function are supposed to cause the deterioration of eggs with increasing age. In this study, we found that mitochondrial NAD+-dependent deacetylase Sirt3 may be involved in mechanisms underlying the deterioration and introduction of Sirt3 may improve the post-fertilization development. Furthermore, we established transgenic mice conditionally expressing Sirt3 in specific cell types including oocytes and eggs, whose phenotype is being analyzed.
