肝再生磷酸酶-3小干扰RNA对异位子宫内膜间质细胞迁移的影响

目的 通过siRNA体外沉默肝再生磷酸酶-3(PRL-3),探讨其对异位子宫内膜间质细胞迁移的影响.方法 原代培养异位子宫内膜间质细胞,运用siRNA技术干扰沉默PRL-3基因,Western blot检测干扰后PRL-3蛋白表达变化,观察细胞板状伪足的形成,采用划痕实验、transwell细胞迁移实验观察并比较细胞迁移能力的改变.结果 经siRNA 干扰沉默后实验组PRL-3蛋白相对表达量较对照组明显下降(P<0.05),细胞形成的板状伪足与对照组相比明显减少,相同时间内发生定向迁移的实验组细胞数为0.87±0.21,空白对照组为1.75±0.28,阴性对照组为1.63±0.39,前者与后两者比较差异有统计学意义(P<0.05).结论 PRL-3 siRNA能有效沉默PRL-3基因,并且使异位子宫内膜间质细胞的迁移能力下降.

Abstract：

Objective To evaluate the effects of PRL-3 siRNA (small interfering RNA) on the migration of endometriotic stromal cells.Methods Primary endometriotic stromal cells were cultured in vitro.Then PRL-3 (phosphatase of regenerating liver-3) siRNA was transfected to silence the PRL-3 gene.And the PRL-3 protein expression was analyzed by Western blot.The changes of cell migration were detected by cell pseudopod formation, scratch test and transwell cell migration test.Results The expression of PRL-3 protein significantly decreased in the experimental group versus two other control groups (P<0.05).The formation of cell pseudopod was much less in experimental group than that in control groups. Within the same time, the number of migration cells was 0.87±0.21 in experimental group.It was less than 1.75±0.28 in blank control group and 1.63±0.39 in negative control group(P<0.05).Conclusion PRL-3 siRNA can down-regulate the PRL-3 gene and decrease the migratory capacity of endometriotic stromal cells.And PRL-3 may be a promising target in the therapeutics of endometriosis.
