探究微小RNA 130b-5p(miR-130b-5p)靶向胰岛素样生长因子-1(
IGF-1
)对人绒毛膜滋养层细胞(HTR8/SVneo)迁移及侵袭的影响。
方法
2
将HTR8/SVneo细胞分为对照组、miR-NC组、miR-130b-5pmimics组、miR-130b-5pmimics+pcDNA3.1组和miR-130b-5pmimics+pcDNA3.1-IGF-1组,双荧光素酶报告基因检测miR-130b-5p和IGF-1的靶向关系;采用实时荧光定量PCR检测HTR8/SVneo细胞样本中miR-130b-5p及

双荧光素酶报告基因结果显示,
IGF-1
是miR-130b-5p的潜在靶基因;相较于miR-NC组,miR-130b-5pmimics组中miR-130b-5p表达水平、细胞增殖抑制率、钙粘附蛋白E(E-cadherin)表达水平显著增加,IGF-1、c-Myc、细胞周期蛋白D1(CyclinD1)表达水平、迁移距离、侵袭细胞数、基质金属蛋白酶9(MMP9)、基质金属蛋白酶2(MMP2)、神经型钙粘附蛋白(N-cadherin)和波形蛋白(Vimentin)表达水平显著降低(

Objective
2
To explore the effects of microRNA 130b-5p (miR-130b-5p) on the migration and invasion of human chorionic trophoblast cells (HTR8/SVneo) by targeting insulin-like growth factor-1 (
IGF-1
).
Methods
2
HTR8/SVneo cells were divided into control group, miR-NC group, miR-130b-5p mimics group, miR-130b-5p mimics+pcDNA3.1 group and miR-130b-5p mimics+pcDNA3.1-IGF-1 group. The dual luciferase reporter gene was used to detect the targeting relationship between miR-130b-5p and
IGF-1
; real-time fluorescent quantitative PCR was used to detect the expression level of miR-130b-5p and
IGF-1
in HTR8/SVneo cell samples; the CCK-8 method was used to detect the proliferation of HTR8/SVneo cells; holographic cytometer and Transwell method was used to analyze the migration and invasion abilities of HTR8/SVneo cells; Western blot method was used to detect the expression of
IGF-1
, invasion, and epithelial-mesenchymal transition (EMT) proteins in HTR8/SVneo cell samples.
Results
2
The results of the dual luciferase reporter gene showed that IGF-1 was a potential target gene of miR-130b-5p; compared with the miR-NC group, the expression level of miR-130b-5p, the cell proliferation inhibition rate, and the expression level of E-cadherin increased significantly in the miR-130b-5p mimics group. The expression levels of
IGF-1
, c-Myc, Cyclin D1, migration distance, number of invaded cells, the expression levels of matrix metalloproteinase 9 (MMP9), matrix metalloproteinase 2 (MMP2), neural cadherin (N-cadherin) and Vimentin were significantly reduced (
P
<
0.05); compared with the miR-130b-5pmimics+pcDNA3.1 group, the cell proliferation inhibition rate and the expression level of E-cadherin in the miR-130b-5p mimics+pcDNA3.1-IGF-1 group were significantly reduced, while the expression levels of c-Myc and CyclinD1, migration distance, number of invasive cells, the expression levels of MMP9, MMP2, Vimentin and N-cadherin were significantly increased (
P
<
0.05).
Conclusion
2
The overexpression of miR-130b-5p may inhibit the migration and invasion of HTR8/SVneo cells by inhibiting the expression of
IGF-1
