Abstract:
Long-term unfertilized oocytes inevitably undergo nuclear and cytoplasmic aging, which will lead to fertilization and development defects. Sirtuins is a NAD+-dependent histone deacetylase, through regulating the metabolism of cells aging delaying and inhibiting effects. In this review, we summarized the changes of aging oocytes in nucleus and cytoplasm. In addition, the functions of sirtuins, the relationship between sirtuins and postovulatory aging, and relationship between sirtuins and autophagy. It is also discussed that the regulation of sirtuins may delay and improve the aging of oocytes.
