Objective

To investigate the molecular mechanism by which long-chain non-coding RNA (lncRNA) X-inactive specific transcript (XIST) regulates the biological activity of trophoblast cells. Methods Human HTR-8/Svneo trophoblast cells were cultured in vitro and separated into control, interference empty (transfected with small interfering RNA-normal control (si-NC)), si-XIST-1 (transfected with si-XIST-1), si-XIST-1+anti-NC (co-transfected with si-XIST-1 and anti-NC), and si-XIST-1+anti-182-5p (co-transfected with si-XIST-1 and anti-182-5p) groups. XIST, miR-182-5p, and hypoxia inducible factor-2α (HIF-2α) mRNA expression levels were measured by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR). Cell proliferation was detected by Cell Counting Kit-8 (CCK-8) and 5-ethynyl-2′-deoxyuridine (EdU) assays. Apoptosis was detected by flow cytometry. Cell migration and invasion abilities were measured by scratch-healing and Transwell experiments. HIF-2α, cleaved-caspase-3, Bcl-2, Bax, matrix metalloproteinase (MMP)-2, and MMP-9 protein levels in cells were measured by Western blot. The targeting relationship of miR-182-5p with XIST and HIF-2α was verified by dualluciferase reporter assay.

Results

XIST and HIF-2α mRNA levels, apoptosis rate, and HIF-2α, cleaved-caspase-3, and Bax protein levels in the si-XIST-1 group were lower than those in the control and interference empty groups, while miR-182-5p, cell viability, EdU-positive rate, scratch-healing rate, number of invaded cells, and Bcl-2, MMP-2, and MMP-9 protein levels were higher (P<0.05). HIF-2α mRNA level, apoptosis rate, and HIF-2α, cleaved-caspase-3, and Bax protein levels in the si-XIST-1+anti-182-5p group were higher than those in the si-XIST-1 and si-XIST-1+ anti-NC groups, while miR-182-5p, cell viability, EdU-positive rate, scratch-healing rate, number of invaded cells, and Bcl-2, MMP-2, and MMP-9 protein levels were lower (P<0.05). LncRNA XIST was able to target miR-182-5p in HTR-8/Svneo cells, and HIF-2α was the target of miR-182-5p.

Conclusions

Knocking-down lncRNA XIST may inhibit HIF-2α expression by competitively binding to miR-182-5p, thereby enhancing the proliferation, migration, and invasion abilities of HTR-8/Svneo cells and inhibiting cell apoptosis.

目的

探究长链非编码RNA(lncRNA)X染色体失活特异性转录本(XIST)调控滋养层细胞生物学活性的分子机制。

方法

体外培养人绒毛膜滋养层细胞HTR-8/Svneo,分为对照组、干扰空载组(转染si-NC)和si-XIST-1组(转染si-XIST-1)、si-XIST-1+anti-NC组(共转染si-XIST-1和anti-NC)、si-XIST-1+anti-182-5p组(共转染si-XIST-1和anti-182-5p)。采用RT-qPCR检测细胞中XIST、miR-182-5p和低氧诱导因子2α(HIF-2α) mRNA表达;CCK-8实验和EdU实验检测细胞增殖活力;流式细胞术检测细胞凋亡;划痕愈合实验、Transwell实验检测细胞迁移、侵袭能力;Western blot检测细胞中HIF-2α、cleaved-caspase-3、Bcl-2、Bax、基质金属蛋白(MMP)-2、MMP-9蛋白表达;双荧光素酶报告实验验证miR-182-5p与XIST、HIF-2α的靶向关系。结果与对照组、干扰空载组比较,si-XIST-1组XIST、HIF-2α mRNA水平、凋亡率及HIF-2α、cleaved-caspase-3、Bax蛋白水平降低,miR-182-5p水平、细胞活力、EdU阳性率、划痕愈合率、侵袭细胞数及Bcl-2、MMP-2、MMP-9蛋白水平升高(P< 0.05);与si-XIST-1组和si-XIST-1+anti-NC组比较,si-XIST-1+ anti-182-5p组HIF-2α mRNA水平、凋亡率及HIF-2α、cleaved-caspase-3、Bax蛋白水平升高,miR-182-5p水平、细胞活力、EdU阳性率、划痕愈合率、侵袭细胞数及Bcl-2、MMP-2、MMP-9蛋白水平降低(P<0.05)。lncRNA XIST可靶向HTR-8/Svneo细胞中的miR-182-5p,HIF-2α是miR-182-5p的靶标。

结论

敲低lncRNA XIST可能是通过竞争性结合miR-182-5p来抑制HIF-2α表达,进而增强HTR-8/Svneo细胞增殖、迁移和侵袭能力,并抑制细胞凋亡。

目的

探究长链非编码RNA(lncRNA)X染色体失活特异性转录本(XIST)调控滋养层细胞生物学活性的分子机制。

方法

体外培养人绒毛膜滋养层细胞HTR-8/Svneo,分为对照组、干扰空载组(转染si-NC)和si-XIST-1组(转染si-XIST-1)、si-XIST-1+anti-NC组(共转染si-XIST-1和anti-NC)、si-XIST-1+anti-182-5p组(共转染si-XIST-1和anti-182-5p)。采用RT-qPCR检测细胞中XIST、miR-182-5p和低氧诱导因子2α(HIF-2α) mRNA表达;CCK-8实验和EdU实验检测细胞增殖活力;流式细胞术检测细胞凋亡;划痕愈合实验、Transwell实验检测细胞迁移、侵袭能力;Western blot检测细胞中HIF-2α、cleaved-caspase-3、Bcl-2、Bax、基质金属蛋白(MMP)-2、MMP-9蛋白表达;双荧光素酶报告实验验证miR-182-5p与XIST、HIF-2α的靶向关系。结果与对照组、干扰空载组比较,si-XIST-1组XIST、HIF-2α mRNA水平、凋亡率及HIF-2α、cleaved-caspase-3、Bax蛋白水平降低,miR-182-5p水平、细胞活力、EdU阳性率、划痕愈合率、侵袭细胞数及Bcl-2、MMP-2、MMP-9蛋白水平升高(P< 0.05);与si-XIST-1组和si-XIST-1+anti-NC组比较,si-XIST-1+ anti-182-5p组HIF-2α mRNA水平、凋亡率及HIF-2α、cleaved-caspase-3、Bax蛋白水平升高,miR-182-5p水平、细胞活力、EdU阳性率、划痕愈合率、侵袭细胞数及Bcl-2、MMP-2、MMP-9蛋白水平降低(P<0.05)。lncRNA XIST可靶向HTR-8/Svneo细胞中的miR-182-5p,HIF-2α是miR-182-5p的靶标。

结论

敲低lncRNA XIST可能是通过竞争性结合miR-182-5p来抑制HIF-2α表达,进而增强HTR-8/Svneo细胞增殖、迁移和侵袭能力,并抑制细胞凋亡。

Objective

To investigate the molecular mechanism by which long-chain non-coding RNA (lncRNA) X-inactive specific transcript (XIST) regulates the biological activity of trophoblast cells. Methods Human HTR-8/Svneo trophoblast cells were cultured in vitro and separated into control, interference empty (transfected with small interfering RNA-normal control (si-NC)), si-XIST-1 (transfected with si-XIST-1), si-XIST-1+anti-NC (co-transfected with si-XIST-1 and anti-NC), and si-XIST-1+anti-182-5p (co-transfected with si-XIST-1 and anti-182-5p) groups. XIST, miR-182-5p, and hypoxia inducible factor-2α (HIF-2α) mRNA expression levels were measured by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR). Cell proliferation was detected by Cell Counting Kit-8 (CCK-8) and 5-ethynyl-2′-deoxyuridine (EdU) assays. Apoptosis was detected by flow cytometry. Cell migration and invasion abilities were measured by scratch-healing and Transwell experiments. HIF-2α, cleaved-caspase-3, Bcl-2, Bax, matrix metalloproteinase (MMP)-2, and MMP-9 protein levels in cells were measured by Western blot. The targeting relationship of miR-182-5p with XIST and HIF-2α was verified by dualluciferase reporter assay.

Results

XIST and HIF-2α mRNA levels, apoptosis rate, and HIF-2α, cleaved-caspase-3, and Bax protein levels in the si-XIST-1 group were lower than those in the control and interference empty groups, while miR-182-5p, cell viability, EdU-positive rate, scratch-healing rate, number of invaded cells, and Bcl-2, MMP-2, and MMP-9 protein levels were higher (P<0.05). HIF-2α mRNA level, apoptosis rate, and HIF-2α, cleaved-caspase-3, and Bax protein levels in the si-XIST-1+anti-182-5p group were higher than those in the si-XIST-1 and si-XIST-1+ anti-NC groups, while miR-182-5p, cell viability, EdU-positive rate, scratch-healing rate, number of invaded cells, and Bcl-2, MMP-2, and MMP-9 protein levels were lower (P<0.05). LncRNA XIST was able to target miR-182-5p in HTR-8/Svneo cells, and HIF-2α was the target of miR-182-5p.

Conclusions

Knocking-down lncRNA XIST may inhibit HIF-2α expression by competitively binding to miR-182-5p, thereby enhancing the proliferation, migration, and invasion abilities of HTR-8/Svneo cells and inhibiting cell apoptosis.
