摘要:

目的  探讨Notch2和Notch3对BeWo及JAR人胎盘绒毛癌滋养细胞株迁移和侵袭能力的影响。方法  通过对BeWo及JAR细胞Notch2和Notch3基因的过表达及干扰,观察两种滋养细胞株迁移、侵袭生物学功能的变化。结果  在BeWo细胞中对Notch2干扰后细胞迁移能力在48 h明显减弱,而72 h的迁移能力及Notch2干扰后的细胞侵袭能力无显著变化;Notch3过表达后细胞迁移能力在48 h显著增强,而72 h则显著减弱;Notch3过表达后细胞侵袭能力在48 h、72 h均显著加强。在JAR细胞中对Notch3干扰后细胞迁移能力在48 h、72 h均明显减弱;而Notch3干扰后细胞的侵袭能力及Notch2过表达后细胞迁移能力、侵袭能力均无明显变化。结论  Notch2 、Notch3影响BeWo及JAR细胞迁移、侵袭功能。

Abstract:

Objective  To investigate the effects of Notch2 and Notch3 on the migration and invasiveness of trophoblast cell lines BeWo and JAR. Methods  The changes of migration and invasiveness of two trophoblast cell lines were observed by over-expression and intervention of Notch2 and Notch3 of BeWo and JAR cells. Results  The migration of BeWo cells at 48 h significantly decreased after the intervention of Notch2, while the migration at 72 h and invasiveness after the intervention of Notch2 did not change remarkably. The migration of BeWo cells at 48 h significantly increased after the over-expression of Notch3, while significantly decreased at 72 h. The invasiveness at 48 and 72 h significantly increased after the over-expression of Notch3. The migration of JAR cells at 48 and 72 h significantly decreased after the intervention of Notch3, while the invasiveness after the intervention of Notch3 and the migration and invasiveness after the over-expression of Notch2 didn’t change remarkably. Conclusion  Notch2 and Notch3 can affect the migration and invasiveness of trophoblast cell lines BeWo and JAR.
