Objective

To explore the effects of long non coding RNA FGD5-AS1 (LncRNA FGD5-AS1) on the migration and invasion of gastric cancer cells by regulating the microRNA-302b-3p (miR-302b-3p)/E2F transcription factor 1 (E2F1) axis.

Methods

Real-time fluorescence quantitative PCR (qRT-PCR) was used to detect the mRNA expression of LncRNA FGD5-AS1, miR-302b-3p, and E2F1 in gastric cancer cell lines (SGC-7901, MKN-45, HGC-27, AGS, BGC-823) and human gastric epithelial cell line GES-1, in order to screen for the best intervention cells. Gastric cancer cells were separated into control group (NC group), sh-NC group, sh-FGD5-AS1 group, sh-FGD5-AS1+anti-miR-NC group, and sh-FGD5-AS1+anti-miR-302b-3p group. qRT-PCR was performed to detect the expression of LncRNA FGD5-AS1, miR-302b-3p, and E2F1 in the cells. MTT assay and flow cytometry were applied to measure cell proliferation and apoptosis, respectively. Scratch and Transwell assays were carried out to measure cell migration and invasion, respectively. Western blotting was carried out to measure the protein levels of E2F1, Ki-67, Bax and Bcl-2. Nude mouse model of transplantable subcutaneous tumor was established to verify the effect of LncRNA FGD5-AS1 on the growth of gastric cancer transplant tumors. Dual luciferase reporter gene and RNA pull-down assays were used to detect the targeting relationship of LncRNA FGD5-AS1 and E2F1 with miR-302b-3p.

Results

Compared with the GES-1 cells, the gastric cancer cell lines SGC-7901, MKN-45, HGC-27, AGS and BGC-823 exhibited significantly increased mRNA levels of LncRNA FGD5-AS1 and E2F1, while decreased level of miR-302b-3p (P<0.05). AGS cells were finally selected for the following experiments. Silencing LncRNA FGD5-AS1 prominently up-regulated miR-302b-3p, down-regulated E2F1, and inhibited cell proliferation, migration, and invasion, and promoted cell apoptosis in gastric cancer AGS cells (P<0.05). Inhibition of miR-302b-3p partially weakened the effects of silencing LncRNA FGD5-AS1 on the proliferation, migration, invasion, and apoptosis of gastric cancer cells (P<0.05). In vivo experiments showed that silencing LncRNA FGD5-AS1 could prominently inhibit the growth of transplanted tumors in mice (P<0.05). RNA pull-down and dual luciferase reporter gene assays confirmed the targeted regulatory relationship of LncRNA FGD5-AS1 and E2F1 with miR-302b-3p.

Conclusion

LncRNA FGD5-AS1 is up-regulated in gastric cancer cells, and its silencing can inhibit the malignant progression of gastric cancer by regulating the miR-302b-3p/E2F1 axis.

目的

探讨长链非编码RNA FGD5-AS1(LncRNA FGD5-AS1)调节微小RNA-302b-3p(miR-302b-3p)/E2F转录因子1(E2F1)轴对胃癌细胞迁移及侵袭的影响。

方法

实时荧光定量PCR反应(qRT-PCR)检测胃癌细胞系(SGC-7901、MKN-45、HGC-27、AGS、BGC-823)及人胃粘膜上皮细胞系GES-1中LncRNA FGD5-AS1、miR-302b-3p、E2F1 mRNA表达,筛选最佳干预细胞。将胃癌细胞分为对照组(NC组)、sh-NC组、sh-FGD5-AS1组、sh-FGD5-AS1+anti-miR-NC组、sh-FGD5-AS1+anti-miR-302b-3p组。qRT-PCR检测细胞中LncRNA FGD5-AS1、miR-302b-3p、E2F1 mRNA的表达水平;MTT法及流式细胞仪分别检测细胞增殖与凋亡;划痕实验及Transwell实验分别检测细胞迁移与侵袭;Western blot检测E2F1、Ki-67、Bax、Bcl-2蛋白表达;裸鼠移植瘤实验验证LncRNA FGD5-AS1对胃癌移植瘤生长的影响;双荧光素酶报告基因和RNA pull-down实验检测LncRNA FGD5-AS1、E2F1与miR-302b-3p的靶向关系。

结果

与GES-1相比,胃癌细胞系(SGC-7901、MKN-45、HGC-27、AGS、BGC-823)中LncRNA FGD5-AS1、E2F1 mRNA表达水平升高,miR-302b-3p表达水平降低(P<0.05),选择AGS细胞进行实验;沉默LncRNA FGD5-AS1表达可显著上调miR-302b-3p表达,下调E2F1表达,抑制胃癌细胞增殖、迁移与侵袭,促进细胞凋亡(P<0.05);抑制miR-302b-3p表达可部分减弱沉默LncRNA FGD5-AS1对胃癌细胞增殖、迁移、侵袭及凋亡的作用(P<0.05);体内实验显示,沉默LncRNA FGD5-AS1表达可显著抑制胃癌移植瘤小鼠肿瘤的生长(P<0.05);RNA pull-down实验、双荧光素酶报告基因实验证实LncRNA FGD5-AS1、E2F1与miR-302b-3p存在靶向调控关系。

结论

LncRNA FGD5-AS1在胃癌细胞中上调表达,沉默LncRNA FGD5-AS1表达可通过调节miR-302b-3p/E2F1轴,抑制胃癌恶性进展。

目的

探讨长链非编码RNA FGD5-AS1(LncRNA FGD5-AS1)调节微小RNA-302b-3p(miR-302b-3p)/E2F转录因子1(E2F1)轴对胃癌细胞迁移及侵袭的影响。

方法

实时荧光定量PCR反应(qRT-PCR)检测胃癌细胞系(SGC-7901、MKN-45、HGC-27、AGS、BGC-823)及人胃粘膜上皮细胞系GES-1中LncRNA FGD5-AS1、miR-302b-3p、E2F1 mRNA表达,筛选最佳干预细胞。将胃癌细胞分为对照组(NC组)、sh-NC组、sh-FGD5-AS1组、sh-FGD5-AS1+anti-miR-NC组、sh-FGD5-AS1+anti-miR-302b-3p组。qRT-PCR检测细胞中LncRNA FGD5-AS1、miR-302b-3p、E2F1 mRNA的表达水平;MTT法及流式细胞仪分别检测细胞增殖与凋亡;划痕实验及Transwell实验分别检测细胞迁移与侵袭;Western blot检测E2F1、Ki-67、Bax、Bcl-2蛋白表达;裸鼠移植瘤实验验证LncRNA FGD5-AS1对胃癌移植瘤生长的影响;双荧光素酶报告基因和RNA pull-down实验检测LncRNA FGD5-AS1、E2F1与miR-302b-3p的靶向关系。

结果

与GES-1相比,胃癌细胞系(SGC-7901、MKN-45、HGC-27、AGS、BGC-823)中LncRNA FGD5-AS1、E2F1 mRNA表达水平升高,miR-302b-3p表达水平降低(P<0.05),选择AGS细胞进行实验;沉默LncRNA FGD5-AS1表达可显著上调miR-302b-3p表达,下调E2F1表达,抑制胃癌细胞增殖、迁移与侵袭,促进细胞凋亡(P<0.05);抑制miR-302b-3p表达可部分减弱沉默LncRNA FGD5-AS1对胃癌细胞增殖、迁移、侵袭及凋亡的作用(P<0.05);体内实验显示,沉默LncRNA FGD5-AS1表达可显著抑制胃癌移植瘤小鼠肿瘤的生长(P<0.05);RNA pull-down实验、双荧光素酶报告基因实验证实LncRNA FGD5-AS1、E2F1与miR-302b-3p存在靶向调控关系。

结论

LncRNA FGD5-AS1在胃癌细胞中上调表达,沉默LncRNA FGD5-AS1表达可通过调节miR-302b-3p/E2F1轴,抑制胃癌恶性进展。

Objective

To explore the effects of long non coding RNA FGD5-AS1 (LncRNA FGD5-AS1) on the migration and invasion of gastric cancer cells by regulating the microRNA-302b-3p (miR-302b-3p)/E2F transcription factor 1 (E2F1) axis.

Methods

Real-time fluorescence quantitative PCR (qRT-PCR) was used to detect the mRNA expression of LncRNA FGD5-AS1, miR-302b-3p, and E2F1 in gastric cancer cell lines (SGC-7901, MKN-45, HGC-27, AGS, BGC-823) and human gastric epithelial cell line GES-1, in order to screen for the best intervention cells. Gastric cancer cells were separated into control group (NC group), sh-NC group, sh-FGD5-AS1 group, sh-FGD5-AS1+anti-miR-NC group, and sh-FGD5-AS1+anti-miR-302b-3p group. qRT-PCR was performed to detect the expression of LncRNA FGD5-AS1, miR-302b-3p, and E2F1 in the cells. MTT assay and flow cytometry were applied to measure cell proliferation and apoptosis, respectively. Scratch and Transwell assays were carried out to measure cell migration and invasion, respectively. Western blotting was carried out to measure the protein levels of E2F1, Ki-67, Bax and Bcl-2. Nude mouse model of transplantable subcutaneous tumor was established to verify the effect of LncRNA FGD5-AS1 on the growth of gastric cancer transplant tumors. Dual luciferase reporter gene and RNA pull-down assays were used to detect the targeting relationship of LncRNA FGD5-AS1 and E2F1 with miR-302b-3p.

Results

Compared with the GES-1 cells, the gastric cancer cell lines SGC-7901, MKN-45, HGC-27, AGS and BGC-823 exhibited significantly increased mRNA levels of LncRNA FGD5-AS1 and E2F1, while decreased level of miR-302b-3p (P<0.05). AGS cells were finally selected for the following experiments. Silencing LncRNA FGD5-AS1 prominently up-regulated miR-302b-3p, down-regulated E2F1, and inhibited cell proliferation, migration, and invasion, and promoted cell apoptosis in gastric cancer AGS cells (P<0.05). Inhibition of miR-302b-3p partially weakened the effects of silencing LncRNA FGD5-AS1 on the proliferation, migration, invasion, and apoptosis of gastric cancer cells (P<0.05). In vivo experiments showed that silencing LncRNA FGD5-AS1 could prominently inhibit the growth of transplanted tumors in mice (P<0.05). RNA pull-down and dual luciferase reporter gene assays confirmed the targeted regulatory relationship of LncRNA FGD5-AS1 and E2F1 with miR-302b-3p.

Conclusion

LncRNA FGD5-AS1 is up-regulated in gastric cancer cells, and its silencing can inhibit the malignant progression of gastric cancer by regulating the miR-302b-3p/E2F1 axis.

胃癌是消化道最常见的恶性肿瘤之一,也是世界上发病率和死亡率最高的癌症之一,目前,治疗胃癌的主要方式是根治性手术切除和放化疗,早期患者5年生存率可接近95%,但大多数患者确诊时为晚期癌症,治疗选择有限[1-2]。复发与转移是晚期胃癌患者死亡主要原因,肿瘤的发生与发展伴随着许多基因的异常表达,如长链非编码RNA(lncRNAs)和微小RNA(miRNAs)参与胃癌的进展机制[3]。长链非编码RNA(long non-coding RNA,lncRNAs)参与调节包括转录、转录后和表观遗传过程。越来越多的证据证实lncRNA在肿瘤发生和转移中的重要作用,参与肿瘤进展、放射耐药、化疗耐药和对靶向治疗的敏感性[4]。LncRNA FGD5-AS1是其中之一,LncRNA FGD5-AS1在胃癌中具有癌基因的作用已得到证实,研究显示,LncRNA FGD5-AS1在胃癌组织中表达升高,高表达LncRNA FGD5-AS1的胃癌患者发生淋巴转移或远处转移的风险较高,且患者预后较差,敲低LncRNA FGD5-AS1的表达会减弱胃癌细胞的增殖和转移能力[5]。然而LncRNA FGD5-AS1在胃癌中具体作用机制尚不清楚。
研究显示,LncRNA FGD5-AS1可以通过海绵miRNA来调节mRNA表达,调控肿瘤细胞的恶性行为[6]。本研究前期经生物信息学分析显示,miR-302b-3p是LncRNA FGD5-AS1下游靶基因,研究显示,miR-302b-3p在胃癌是一种抑癌因子,过表达miR-302b-3p可抑制细胞增殖和细胞周期G1-S转变,诱导细胞凋亡[7]。此外,经生物信息学工具分析显示miR-302b-3p与E2F转录因子1(E2F1)有靶向结合位点,可能是E2F1的上游调控因子。E2F1是一种基因调控因子,参与调控肿瘤细胞增殖、血管生成等过程,抑制E2F1表达可抑制胃癌细胞迁移与侵袭[8-9]。通过以上研究本研究推测LncRNA FGD5-AS1可能作为胃癌细胞中竞争性内源性RNA(ceRNA),通过海绵化miR-302b-3p调控E2F1表达影响胃癌的发生发展。因此,本研究主要探讨LncRNA FGD5-AS1对胃癌恶性生物学行为及miR-302b-3p/E2F1轴的影响,初步探讨LncRNA FGD5-AS1在胃癌中的作用机制,为胃癌的治疗提供靶点。

胃癌是全球第五大最常见癌症,尽管胃癌早期诊断及新兴的治疗方法已取得很大进步,作为一种极具侵袭性的肿瘤,胃癌的治疗效果仍远不能令人满意[10]。LncRNAs在肿瘤中的染色质重塑、免疫逃逸、代谢和耐药性中等过程中发挥调控作用,其在胃癌中的异常表达,与肿瘤的恶性进展有关[11]。据报道显示,LncRNA FGD5-AS1在多种肿瘤中发挥致癌基因的作用,如结肠癌、口腔鳞状细胞癌、前列腺癌、肝癌、膀胱癌等,其高表达可促进肿瘤细胞增殖、迁移、侵袭[12-14]。LncRNA FGD5-AS1还与肿瘤细胞的耐药性有关,如XIA等[15]研究显示,LncRNA FGD5-AS1在建立的5-氟尿嘧啶(5-Fu)耐药宫颈癌细胞中表达显著上调,通过调控miR-130a-3p/YTHDF2轴促进宫颈癌5-Fu耐药。已有报道显示,LncRNA FGD5-AS1在胃癌中表达水平升高,其过表达与胃癌淋巴结转移相关,并预示胃癌患者生存期较差,LncRNA FGD5-AS1过表达通过结合稳定YBX1蛋白抑制细胞衰老和ROS产生,从而促进GC进展[16]。但其在胃癌中的作用机制仍需更深入的研究。本研究结果显示,LncRNA FGD5-AS1在胃癌细胞中表达水平显著升高,与报道[16]类似,沉默LncRNA FGD5-AS1表达可显著抑制胃癌细胞增殖、迁移、侵袭,促进细胞凋亡,表明LncRNA FGD5-AS1在胃癌中作为致癌基因发挥作用。
多项研究显示,LncRNA作为miRNA海绵,并作为ceRNA发挥作用,通过间接调节mRNA的翻译参与肿瘤的发生发展。多项报道表明LncRNA FGD5-AS1可调控多种miRNA参与调节肿瘤细胞的恶性行为[17]。本研究通过生物信息学分析发现,miR-302b-3p可能作为LncRNA FGD5-AS1的下游靶分子。miR-302b-3p是miRNA之一,具有组织特异性,通过靶向调节mRNA表达,在不同的癌症中发挥不同的生物学功能,如胰腺癌中发挥抑癌的作用,敲低LncRNA SNHG16可上调miR-302b-3p表达,降低胰腺癌细胞的增殖、迁移和侵袭[18]。而在喉癌中起着促癌基因的作用[19]。研究显示,miR-302b-3p在胃癌组织与细胞中下调表达,circ_HN1通过海绵化miR-302b-3p上调ROCK2,在胃癌中发挥致癌作用[20]。本研究通过双荧光素酶实验与RNA pull-down实验,在分子水平直接证实了LncRNA FGD5-AS1与miR-302b-3p间的特异性结合,结合胃癌细胞中miR-302b-3p表达显著下调的观察结果,从“表达”与“互作”两个维度共同支持LncRNA FGD5-AS1作为miR-302b-3p功能性分子海绵的假设。在功能层面,抑制miR-302b-3p表达可部分回补因沉默LncRNA FGD5-AS1所引发的细胞增殖、迁移与侵袭抑制及凋亡促进作用,这一“表型回复”实验不仅进一步验证了二者在调控胃癌恶性行为中的上下游关系,更表明miR-302b-3p是LncRNA FGD5-AS1驱动肿瘤进展过程中的关键下游效应分子。
本研究还显示,E2F1是miR-302b-3p的下游靶基因。E2F1属于E2F家族成员,是一种转录因子,作为转录激活剂驱动基因表达,调控细胞周期,促进细胞增殖。E2F1在多种肿瘤中作为致癌因子,如在口腔鳞状细胞癌、胃癌、乳腺癌、结直肠癌中表达广泛,促进癌细胞增殖与转移[21-22]。本研究显示,在胃癌细胞中E2F1表达上调。功能干预实验显示,沉默LncRNA FGD5-AS1表达可有效下调E2F1蛋白水平,而抑制其下游靶点miR-302b-3p则能够逆转这一效应,促使E2F1表达回升,提示二者在调控E2F1表达中存在功能上的拮抗关系。为进一步验证miR-302b-3p与E2F1之间的直接结合作用,本研究开展了RNA pull-down实验,结果显示经生物素标记的野生型miR-302b-3p可显著富集E2F1,进一步从分子互作层面确认了miR-302b-3p对E2F1的直接靶向关系。体内实验结果表明,沉默LncRNA FGD5-AS1表达同样显著抑制胃癌移植瘤生长,并伴随瘤体内miR-302b-3p表达的上调与E2F1表达的下降,上调miR-302b-3p表达,整体结果与体外实验一致。以上系列证据共同表明,LncRNA FGD5-AS1通过吸附miR-302b-3p解除其对E2F1的抑制作用,进而激活E2F1所介导的促癌信号,该miR-302b-3p/E2F1轴是其作为癌基因行使功能的关键下游通路。此外,为探究本研究的临床相关性,基于TCGA公共数据库分析了FGD5-AS1/miR-302b-3p/E2F1轴在胃癌队列中的表达与预后价值。分析结果显示,E2F1在胃癌组织中的表达显著高于癌旁正常组织,这与我们的体外发现相一致。然而,LncRNA FGD5-AS1的表达水平及预后价值在该队列中未达到统计学显著性。推测,这种不一致性可能源于胃癌的高度异质性,本研究所揭示的FGD5-AS1/miR-302b-3p/E2F1调控轴或许在特定的胃癌分子亚型中扮演了更关键的角色,而在混合人群的分析中其信号被稀释。此外,肿瘤微环境中复杂的细胞组成也可能干扰了来自癌细胞本身的特定lncRNA信号。值得注意的是,在严格控制遗传背景的细胞系及动物模型中,本研究清晰地证实了该轴的功能性作用。未来的研究将在更均一的患者队列或特定亚型中进一步验证该通路的临床意义。
然而,本研究仍存在一定的局限性。本研究的体内实验主要依赖于皮下移植瘤模型,该模型虽然为初步评估肿瘤细胞的体内增殖能力提供了一个稳定且可量化的平台,但其肿瘤微环境(如组织特异性、免疫细胞浸润及血管生成等方面)与人体真实情况或原位肿瘤模型存在差异。因此,本研究结果在反映胃癌在原位微环境中的完整生物学行为方面可能存在不足。在未来的研究中,构建胃癌原位移植瘤模型对于进一步验证LncRNA FGD5-AS1/miR-302b-3p/E2F1轴在更接近生理病理条件下的功能,特别是对其在肿瘤侵袭和转移过程中作用的深入探索,将是至关重要且必要的方向。
综上所述,LncRNA FGD5-AS1在胃癌细胞中上调表达,沉默LncRNA FGD5-AS1表达可通过调节miR-302b-3p/E2F1轴,抑制胃癌恶性进展。本研究新发现LncRNA FGD5-AS1在胃癌中可能的作用机制,可能成为胃癌的治疗靶点,但其在临床中的应用价值仍需进一步研究。
