摘要
目的探讨缺氧条件下Notch信号通路在滋养细胞中的表达改变。方法利用实时荧光定量PCR(RT-qPCR)技术检测二氯化钴(CoCl2)化学缺氧条件下人早孕绒毛滋养细胞株(the human first-trimester extravillous tropho-blast cell line,TEV-1)中Notch1及Jagged1 mRNA的表达情况。结果 (1)与正常对照组相比,缺氧条件下滋养细胞Notch1 mRNA表达量无明显变化(P>0.05)。(2)随着缺氧时间的延长,滋养细胞Jagged1 mRNA表达量逐渐降低,与正常对照组相比具有统计学意义(P<0.05)。结论缺氧条件下滋养细胞Notch1及Jagged1表达平衡失调,可能参与滋养细胞功能调控。
Objective : To investigate the change of Notch signaling in hypoxic trophoblasts. Methods : By using quantitative real - time PCR, we detected the expression of Notchl and Jaggedl in human extravillous trophoblast cell line TEV - 1, which was cultured under Cobalt chloride ( CoCl2 ) in vitro. Results : ( 1 ) The mRNA expression of Notchl in control groups showed no difference as compared with hypoxic groups (P 〉 0. 05 ). (2) The mRNA expression of Jaggedl was gradually reduced with the extending of time and was significantly decreased as compared with hypoxic groups ( P 〈 0. 05 ). Conclusions : The imbalance expression of Notchl and Jaggedl in hypoxic trophoblasts may contribute to functional regulation of trophoblasts.
