Abstract
mRNA expression of p53, p21, BCL-2, Bax, Noxa and MDM2 in decidual tissue (endometrium) of 50 patients with missed abortions, 47 patients with spontaneous abortions, and 57 patients with artificial abortion (control group) at 6–10 weeks of gestation were examined using reverse transcription quantitative polymerase chain reaction. Expression of p53 mRNA had no significant differences in patients with missed and spontaneous abortions. Significant increase of proapoptotic protein Noxa, accompanied with anti-apoptotic protein BCL-2 elevation was observed in the endometrium of patients with missed abortions. In patients with spontaneous abortions, only increase of Noxa has been observed. It can be suggested, that increase of BCL-2 in patients with missed abortions, when embryo resorption has happened, protects nearby embryos in case of multiple pregnancies. No significant changes of p21 mRNA were discovered in both groups, which indicates, that cell cycle arrest is not involved in the pathogenesis of early miscarriages. No significant changes of Bax and MDM2 mRNA expression were discovered in decidual tissue of patients with missed and spontaneous abortions.
