Research Abstract

Condition of primary culture of fertilized ovum was established to realized the mechanism of embryonic lethal of knockout mouse of PHGPx (GPx4). Inner cell mass (ICM) and prominent expression of PHGPx were formed during 3days culture of wild type of embryo. On the other hand, growth of ICM was significantly suppressed in PHGPx-KO embryo and was disappeared during 7 days culture. We prepared PHGPx-hetero mouse which were introduced exogeous PHGPx gene. KO-PHGPx mouse was rescued by the introduction of PHGPx gene.
Low expression of PHGPx in sperm caused severe infertility of male. EDS induced infertility of mouse by the injury of testis. Injury of testis was more prominent in hetero mouse whose expression of PHGPx was almost half as compare to wild type of mouse.
