Özet

Background: Syncytin-1 and syncytin-2 which are endogenous retroviral genes products play a great role in syncytialization during trophoblast differentiation in normal placental tissues. In aneuploidic placentas due to the low level of pregnancy-induced hormones an alteration was occurred in the syncytialization process, while in the presence of cytogenetically abnormal karyotype the effect of syncytin gene expression levels on syncytialization process and in occured to spontaneous abortions is not clear. To reveal this, we investigated in syncytin-1 and syncytin-2 genes expression levels of chromosomally abnormal and normal trophophoblastic tissues and we also discussed the effect of the syncytin gene expression levels to the occurense of the spontaneous abortion.
