AP-2α對滋養(yǎng)細胞凋亡、侵襲作用的影響
[Abstract]:Objective to investigate the effects of transcription factor activator protein-2 偽 (Transcription factor activator protein-2 偽 (AP-2 偽) on the apoptosis and invasion of trophoblastic Be Wo and its role in the development of preeclampsia (preeclampsia,PE). Methods the constructed eukaryotic expression vector of p IRES2-EGFP/AP-2 偽 was transfected into trophoblastic Be Wo cells by transient transfection. The expression of AP-2 偽 m RNA and protein in Be Wo cells was detected by real timePCR and Western blot methods. Apoptosis was detected by flow cytometry and invasiveness was detected by Transwell assay. Results the expression of AP-2 偽 m RNA and protein in Be Wo cells transfected with AP-2 偽 was significantly higher than that in control group (P0.05). The results of flow cytometry showed that the number of apoptosis in AP-2 偽 transfected group was significantly higher than that in control group (P0.05). Compared with the control group, the invasiveness of AP-2 偽 transfected group was significantly decreased by Transwell (P0.05), and the invasiveness of the transfected group was significantly lower than that of the control group (P0.05). Conclusion AP-2 偽 promotes trophoblast apoptosis and reduces the invasion of trophoblast, which results in superficial implantation of trophoblast layer, which provides a theoretical basis for the study of pathogenesis of preeclampsia.
