Outline of Final Research Achievements |
We examined whether poor embryo development of in vivo aged mouse oocytes (aged oocytes) could be improved by regulation of endoplasmic reticulum stress (Endoplasmic reticulum stress: ERS) or not. Because expression level of GRP78 (molecular chaperone induced by ERS) was the highest in unfertilized oocytes, we treated unfertilized aged oocytes with salburinal (inhibitor of ERS) before IVF. Salburinal treated aged oocytes showed significantly decrease in abnormal embryos and significantly increase in morula, blastocysts and hatched blastocysts. Regulation of ERS due to inhibition of dephosphorylation of eIF2α-PERK pathway by salburinal might improve embryo development of aged oocytes.
