重度子痫前期患者胎盘乙酰肝素酶转录剪切体的表达水平及其意义
首发时间:2015-07-08
摘要:目的:乙酰肝素酶的异常表达可影响可溶性血管内皮生长因子受体1的表达,而可溶性血管内皮生长因子受体-1与重度子痫前期的发生发展相关,因此乙酰肝素酶可能与重度子痫前期相关。mRNA前体选择性剪切在机体发育、生理功能的发挥及疾病发生发展等方面发挥着非常重要的作用,目前并未见有关乙酰肝素酶4种转录剪切体在重度子痫前期患者胎盘表达的研究报道。方法:用荧光定量PCR法检测重度子痫前期患者、正常妊娠妇女胎盘中乙酰肝素酶4种转录剪切体的表达。结果:重度子痫前期组胎盘组织母面中乙酰肝素酶转录剪切体4表达水平显著高于正常妊娠组,两者表达量相差高达55倍,差异有统计学意义(P= 0.0225),而子面及其它剪切体在两组样本中的表达均无统计学差异。结论:乙酰肝素酶转录剪切体4母面的高表达可能与重度子痫前期的发生发展相关。

The expression of transcript variants of Heparanase in severe preeclampsia
Abstract:The excessive expression of heparanase was associated with the release of soluble fms-like tyrosine kinase receptor-1. It has been confirmed that the abnormal expression of soluble fms-like tyrosine kinase receptor-1 is associated with the pathogenesis of preeclampsia. We thus hypothesized that heparanase may have a certain relationship with severe preeclampsia. mRNA alternative splicing played very important roles in development, physiologic function and disease. The transcript variants of heparanase in planceta of severe preeclampsia and normal control were detected by realtime PCR. The result showed heparanase transcript variant 4 was significantly higher in the maternal side of the placenta in severe preeclampsia group than that in normal pregnancy group (P<0.05), the expression difference was up to 55 times.
