目的
2
探讨敲低miR-375对子痫前期(PE)滋养细胞模型增殖、凋亡的影响及作用机制。
方法
2
取人绒毛膜滋养细胞株HTR-8/Svneo,随机分为常氧对照组、PE模型组、miR-NC组和miR-375 inhibitor组。其中,miR-NC组和miR-375 inhibitor组细胞分别转染miR-NC和miR-375 inhibitor;常氧对照组细胞在常氧环境下培养,其余3组细胞均在缺氧条件下培养以建立PE滋养细胞模型。采用RT-PCR检测miR-375的表达,EdU荧光染色、CCK-8实验检测细胞增殖情况,流式细胞术检测细胞凋亡情况,Western blot检测YAP1蛋白及凋亡相关蛋白(Bcl-2、caspase-3及Bax蛋白)的表达。双荧光素酶基因实验检测miR-375与YAP1的靶向调控关系。
结果
2
与常氧对照组比较,PE模型组细胞miR-375表达升高(
P
<
0.05),EdU阳性细胞百分比下降(
P
<
0.05),细胞增殖能力降低(
P
<
0.05),细胞凋亡率升高(
P
<
0.05),Bax、caspase-3蛋白表达水平升高(
P
<
0.05),YAP1、Bcl-2蛋白表达水平降低(
P
<
0.05)。PE模型组和miR-NC组细胞上述各项指标比较差异均无统计学意义(
P
>
0.05)。与miR-NC组比较,miR-375 inhibitor组细胞miR-375表达降低(
P
<
0.05),EdU阳性细胞百分比升高(
P
<
0.05),细胞增殖能力增强(
P
<
0.05),细胞凋亡率降低(
P
<
0.05),Bax、caspase-3蛋白表达降低(
P
<
0.05),YAP1、Bcl-2蛋白表达升高(
P
<
0.05)。双荧光素酶报告基因实验显示,miR-375对YAP1具有靶向调控作用(
P
<
0.05)。
结论
2
敲低miR-375可促进PE滋养细胞增殖并抑制细胞凋亡,其作用机制可能与其对YAP1基因的靶向调控有关。
Objective
2
To investigate the effects of miR-375 knockdown on the proliferation and apoptosis of trophoblast cells in preeclampsia (PE) model and its mechanism.
Methods
2
Human chorionic trophoblast cell line HTR-8/Svneo was randomly divided into the normoxic control group, the PE model group, the miR-NC group, and the miR-375 inhibitor group. Among them, cells in the miR-NC group and miR-375 inhibitor group were transfected with miR-NC and miR-375 inhibitor, respectively;cells in the normoxic control group were cultured in a normoxic enviroment,and cells in the remaining three groups were cultured under hypoxic conditions to establish the PE trophoblast cell model. The expression of miR-375 was detected by RT-PCR, the proliferation of cells was detected by EdU fluorescence staining and CCK-8 assay, the apoptosis of cells was detected by flow cytometry, and the expression of YAP1 protein and apoptosis-related proteins (Bcl-2, caspase-3, and Bax proteins) were detected by Western blot. The target regulation relationship between miR-375 and YAP1 was detected by dual luciferase reporter gene assay.
Results
2
Compared with the normoxic control group, the PE model group showed an increase in the expression of miR-375 (
P
<
0.05), a decrease in the proportion of EdU-positive cells (
P<
0.05), a decline in the cell proliferation ability (
P
<
0.05), increases in the apoptosis rate (
P
<
0.05) and the expression levels of Bax and caspase-3 proteins (
P
<
0.05), and a decrease in the expression levels of YAP1 and Bcl-2 proteins (
P
<
0.05). There was no significant difference in the above indicators between the PE model group and the miR-NC group (
P
>
0.05). Compared with the miR-NC group, the miR-375 inhibitor group showed a lower expression of miR-375 (
P
<
0.05), an increased percentage of EdU-positive cells (
P
<
0.05), an enhanced cell proliferation ability (
P
<
0.05), a lower apoptosis rate (
P
<
0.05), and a lower expression of Bax and caspase-3 proteins (
P
<
0.05), while with a higher expression of YAP1 and Bcl-2 proteins (
P
<
0.05). The dual luciferase reporter gene assay showed that miR-375 had a targeted regulatory effect on YAP1 (
P
<
0.05).
Conclusion
2
Knocking down miR-375 can promote the proliferation and inhibit the apoptosis of PE trophoblast cells, and its mechanism may be related to its targeted regulation of YAP1 gene.
