miR-26a-5p調(diào)控MCL-1在孕產(chǎn)婦子癇前期中表達(dá)的臨床意義
[Abstract]:Objective: to investigate the clinical significance of microRNA-26a-5p (miR-26a-5p) regulating the expression of myeloid leukemia factor 1 (myeloid cell leukemia-1 MCL-1 in preeclampsia. Methods: there were 21 normal pregnancies, 13 hypertensive pregnant women, 15 mild preeclampsia and 26 severe preeclampsia. Real-time PCR was used to analyze the expression of miR-26a-5p in plasma and placenta and MCL-1 mRNA in placenta. Western blotting was used to analyze the expression of MCL-1 protein in placenta and its clinical significance. Results: the expression of miR-26a-5p increased gradually in maternal plasma and placenta (P0.01), but the expression of MCL-1 mRNA in placenta decreased significantly (P0.01), and the expression of miR-26a-5p and MCL-1 protein in placenta was negatively correlated (P0.01). The up-regulation of miR-26a-5p expression in maternal plasma and placenta was negatively correlated with gestational age, maternal plasma albumin level and fetal weight, but positively correlated with maternal blood pressure and urine protein level (P0.01). The down-regulation of MCL-1 expression in placental tissue was reversed. Conclusion the high expression of miR-26a-5p may play an important role in the development of preeclampsia by down-regulating the expression of MCL-1.
