ApoE基因多態(tài)性與早發(fā)性卵巢功能不全的相關(guān)性和作用機(jī)制研究ApoE基因多態(tài)性與早發(fā)性卵巢功能不全的相關(guān)性和作用機(jī)制研究

摘要：本研究旨在探討ApoE基因多態(tài)性與早發(fā)性卵巢功能不全的相關(guān)性以及其作用機(jī)制。我們采用病例-對(duì)照研究方法，招募了188名早發(fā)性卵巢功能不全患者和191名健康對(duì)照者，并采集了其血液樣本進(jìn)行ApoE基因多態(tài)性分析。結(jié)果顯示，ApoEε2基因型在早發(fā)性卵巢功能不全組中的出現(xiàn)率顯著高于對(duì)照組（P<0.05），而ApoEε4基因型在早發(fā)性卵巢功能不全組中出現(xiàn)率顯著低于對(duì)照組（P<0.05）。此外，我們還通過實(shí)驗(yàn)室研究探討了ApoE基因不同基因型對(duì)卵巢功能的影響。實(shí)驗(yàn)結(jié)果顯示，ApoE基因不同基因型對(duì)卵巢功能的影響可能與各自不同的遺傳表達(dá)方式和脂質(zhì)代謝有關(guān)。

SeveralstudieshavesuggestedthattheApoEgenepolymorphismmaybeassociatedwithPOI.Forinstance,astudyconductedinChinafoundthattheε4allelefrequencywassignificantlylowerinwomenwithPOIcomparedtohealthycontrols.AnotherstudyconductedinItalyreportedthattheε2allelefrequencywassignificantlyhigherinwomenwithPOIcomparedtocontrols.However,otherstudieshavereportedconflictingresults.
