Objective To investigate the regulatory effect and molecular mechanism of circAPLP2 on invasion and metastasis of colorectal cancer cell SW480. Methods The online database Starbase was used to predict the binding sites of circAPLP2 and miR-497-5p, and TargetScan was used to predict the binding sites of miR-497-5p and FGFR1. The relative expression levels of circAPLP2 and miR-497-5p in LoVo, DLD1, SW480, SW620, Caco-2 and HCoEpiC cells were detected by qRT-PCR, and the relative expression level of FGFR1 protein was detected by Western blotting. SW480 cells were taken and set up as follows:(1) siNC group (transfected with siControl) and sicircAPLP2 group (transfected with sicircAPLP2), the expressions of circAPLP2, miR-497-5p, FGFR1 mRNA were detected by qRT-PCR, and the expression of FGFR1 protein was detected by Western blotting.(2) Vector group (transfected with empty plasmid) and circAPLP2 group (transfected with circAPLP2 overexpression plasmid), the expressions of miR-497-5p and FGFR1 mRNA were detected by qRT-PCR, and the expression of FGFR1 protein was detected by Western blotting. (3) siNC group (transfected with siControl), sicircAPLP2 group (transfected with sicircAPLP2) and sicircAPLP2+miR-497-5p inhibitor group (transfected with sicircAPLP2 and miR-497-5p inhibitor), the cell invasion was detected by Transwell, the cell migration was detected by scratch test, and the expressions of EMT marker proteins (E-cadherin, Twist1, N-cadherin and Vimentin) were detected by Western blotting. (4) NC miRNA group (transfected with NC-miRNA) and miR-497-5p mimics group (transfected with miR-497-5p mimics), or NC-inhibitor group (transfected with NC-inhibitor) and miR-497-5p inhibitor group (transfected with miR-497-5p inhibitor), the expression of FGFR1 was detected by qRT-PCR and Western blotting.(5) pcDNA-Control group (transfected with pcDNA-Control) and pcDNA-FGFR1 group (transfected with pcDNA-FGFR1), the expression of FGFR1 protein was detected by Western blotting. (6) NC-miRNA group (transfected with negative control), miR-497-5p mimics group (transfected with miR-497-5p mimics) and miR-497-5p mimics+pcDNA-FGFR1 group (co transfected with miR-497-5p mimics and pcDNA-FGFR1), the cell invasion, migration and the expression of FGFR1 and EMT marker proteins(E-cadherin, Twist1, N-cadherin, Vimentin) were detected by Transwell, scratch test or Western blotting. The circAPLP2-WT or circAPLP2-MT report plasmid was co-transfected with NC-miRNA or miR-497-5p mimics respectively for 48 h in SW480 cells, and the FGFR1-WT or FGFR1-MT report plasmid was co-transfected with miR-497-5p mimics and circAPLP2 respectively for 48 h in SW480 cells, and the luciferase activity was detected by the luciferase reporter gene detection system. Results The analysis results by Starbase and TargetScan showed that binding sites existed between circAPLP2 and miR-497-5p, and between miR-497-5p and FGFR1. Compared with human colon epithelial cell HCoEpiC, the relative expression level of circAPLP2 in colorectal cancer cells LoVo, DLD1, SW480, SW620 and Caco-2 increased significantly, while of miR-497-5p significantly decreased, and the relative expression level of FGFR1 protein significantly increased (P<0.05). After knocking down the expression of circAPLP2, compared with siCN group, the number of invasive cells in sicircAPLP2 group decreased (P<0.001), and the cell healing rate of scratches decreased (P<0.001), the expression of E-cadherin protein increased, and the protein expressions of Twist1, N-cadherin and Vimentin decreased (P<0.05). The results of dual luciferase reporter assay showed that miR-497-5p mimics decreased circAPLP2-MT luciferase activity significantly (P<0.001); MiR-497-5p inhibitor reverses the inhibitory effect of sicircAPLP2 on EMT, migration and invasion of colorectal cancer cells, as the number of invasive cells increased (P<0.001), the scratch healing rate increased (P<0.01), the expression of E-cadherin protein decreased, and the expression of Twist1, N-cadherin, and Vimentin protein increased (P<0.05). Dual luciferase reporter assay results showed that miR-497-5p mimics significantly reduced FGFR1-MT luciferase activity (P<0.001). Over-expression of FGFR1 reversed the inhibition of miR-497-5p overexpression on colorectal cancer cell migration and invasion, manifested as increased number of invasive cells (P<0.001), increased scratch healing rate (P<0.01), decreased expression of E-cadherin, increased expressions of N-cadherin, Twist1 and Vimentin (P<0.05). Conclusion The expression level of circAPLP2 increases in colorectal cancer cells, it may promote the expression of FGFR1 through competitive combination with miR-497-5p, thus promoting EMT, invasion and migration of colorectal cancer cells.

Objective To investigate the regulatory effect and molecular mechanism of circAPLP2 on invasion and metastasis of colorectal cancer cell SW480. Methods The online database Starbase was used to predict the binding sites of circAPLP2 and miR-497-5p, and TargetScan was used to predict the binding sites of miR-497-5p and FGFR1. The relative expression levels of circAPLP2 and miR-497-5p in LoVo, DLD1, SW480, SW620, Caco-2 and HCoEpiC cells were detected by qRT-PCR, and the relative expression level of FGFR1 protein was detected by Western blotting. SW480 cells were taken and set up as follows:(1) siNC group (transfected with siControl) and sicircAPLP2 group (transfected with sicircAPLP2), the expressions of circAPLP2, miR-497-5p, FGFR1 mRNA were detected by qRT-PCR, and the expression of FGFR1 protein was detected by Western blotting.(2) Vector group (transfected with empty plasmid) and circAPLP2 group (transfected with circAPLP2 overexpression plasmid), the expressions of miR-497-5p and FGFR1 mRNA were detected by qRT-PCR, and the expression of FGFR1 protein was detected by Western blotting. (3) siNC group (transfected with siControl), sicircAPLP2 group (transfected with sicircAPLP2) and sicircAPLP2+miR-497-5p inhibitor group (transfected with sicircAPLP2 and miR-497-5p inhibitor), the cell invasion was detected by Transwell, the cell migration was detected by scratch test, and the expressions of EMT marker proteins (E-cadherin, Twist1, N-cadherin and Vimentin) were detected by Western blotting. (4) NC miRNA group (transfected with NC-miRNA) and miR-497-5p mimics group (transfected with miR-497-5p mimics), or NC-inhibitor group (transfected with NC-inhibitor) and miR-497-5p inhibitor group (transfected with miR-497-5p inhibitor), the expression of FGFR1 was detected by qRT-PCR and Western blotting.(5) pcDNA-Control group (transfected with pcDNA-Control) and pcDNA-FGFR1 group (transfected with pcDNA-FGFR1), the expression of FGFR1 protein was detected by Western blotting. (6) NC-miRNA group (transfected with negative control), miR-497-5p mimics group (transfected with miR-497-5p mimics) and miR-497-5p mimics+pcDNA-FGFR1 group (co transfected with miR-497-5p mimics and pcDNA-FGFR1), the cell invasion, migration and the expression of FGFR1 and EMT marker proteins(E-cadherin, Twist1, N-cadherin, Vimentin) were detected by Transwell, scratch test or Western blotting. The circAPLP2-WT or circAPLP2-MT report plasmid was co-transfected with NC-miRNA or miR-497-5p mimics respectively for 48 h in SW480 cells, and the FGFR1-WT or FGFR1-MT report plasmid was co-transfected with miR-497-5p mimics and circAPLP2 respectively for 48 h in SW480 cells, and the luciferase activity was detected by the luciferase reporter gene detection system. Results The analysis results by Starbase and TargetScan showed that binding sites existed between circAPLP2 and miR-497-5p, and between miR-497-5p and FGFR1. Compared with human colon epithelial cell HCoEpiC, the relative expression level of circAPLP2 in colorectal cancer cells LoVo, DLD1, SW480, SW620 and Caco-2 increased significantly, while of miR-497-5p significantly decreased, and the relative expression level of FGFR1 protein significantly increased (P<0.05). After knocking down the expression of circAPLP2, compared with siCN group, the number of invasive cells in sicircAPLP2 group decreased (P<0.001), and the cell healing rate of scratches decreased (P<0.001), the expression of E-cadherin protein increased, and the protein expressions of Twist1, N-cadherin and Vimentin decreased (P<0.05). The results of dual luciferase reporter assay showed that miR-497-5p mimics decreased circAPLP2-MT luciferase activity significantly (P<0.001); MiR-497-5p inhibitor reverses the inhibitory effect of sicircAPLP2 on EMT, migration and invasion of colorectal cancer cells, as the number of invasive cells increased (P<0.001), the scratch healing rate increased (P<0.01), the expression of E-cadherin protein decreased, and the expression of Twist1, N-cadherin, and Vimentin protein increased (P<0.05). Dual luciferase reporter assay results showed that miR-497-5p mimics significantly reduced FGFR1-MT luciferase activity (P<0.001). Over-expression of FGFR1 reversed the inhibition of miR-497-5p overexpression on colorectal cancer cell migration and invasion, manifested as increased number of invasive cells (P<0.001), increased scratch healing rate (P<0.01), decreased expression of E-cadherin, increased expressions of N-cadherin, Twist1 and Vimentin (P<0.05). Conclusion The expression level of circAPLP2 increases in colorectal cancer cells, it may promote the expression of FGFR1 through competitive combination with miR-497-5p, thus promoting EMT, invasion and migration of colorectal cancer cells.

结直肠癌是全球范围内最常见的恶性肿瘤之一,其发病率在恶性肿瘤中居第4位,病死率居第2位,严重威胁人类的健康[1]。近年来,手术切除联合化疗、放疗的临床治疗方案在一定程度上改善了结直肠癌患者的生存质量,但病死率仍高达10.2%,而结直肠癌侵袭、转移是导致患者死亡的主要原因[2-3]。侵袭、转移作为肿瘤发生发展中的恶性生物学行为,严重影响患者的预后,上皮-间质转化(epithelial-mesenchymal transition,EMT)是肿瘤发生侵袭、转移的前提[4],深入阐明结直肠癌EMT、侵袭、转移的发生机制是延长患者生存期的关键。近年来,RNA组学成为生命科学关注的热点。在人类基因组中超过95%的基因不编码蛋白质,被称为非编码RNA[5],其中环状RNA(circRNA)是一类特殊的非编码RNA,也是RNA领域最新的研究热点[6]。circRNA因其组织特异性、稳定性和高度保守性,已成为肿瘤诊断及预后预测的重要标志物[7]。既往研究发现,在结直肠癌中下调miR-497-5p表达,可导致成纤维细胞生长因子受体1(fibroblast growth factor receptor 1,FGFR1)表达增加,从而促进癌细胞增殖[8]。本研究探讨了circAPLP2竞争性结合miR-497-5p上调FGFR1在结直肠癌细胞中的作用,以期为结直肠癌靶向药物研发提供新的思路。

结直肠癌是我国癌症相关死亡的第五大原因,尽管随着治疗方法的不断进步,结直肠癌患者5年生存率有所提高,但术后复发和远处转移仍是患者死亡的主要原因[9]。EMT是肿瘤增殖和转移的重要组成部分,在其发生过程中,上皮细胞由上皮类型转变为间质类型,失去细胞间连接及极性,获得间质细胞形态,增强了细胞的迁移和侵袭能力[10]。研究发现,结直肠癌肝转移患者癌组织中上皮细胞标志物E-cadherin表达降低[11];结直肠癌细胞发生EMT后,间质细胞标志物Twist1表达增加,细胞侵袭与迁移能力增强[12]。因此探究结直肠癌细胞EMT、增殖和转移能力的调控机制,对制订结直肠癌的治疗策略尤为重要。
circRNAs作为机体非编码RNA的重要组成部分,在肿瘤的发展中发挥了关键作用。已有研究证实,在结直肠癌中circPTK2、circCAMSAP1、circHIPK3等多种circRNA表达水平异常,是患者预后不良的重要预测指标[13-14]。circRNA参与调控肿瘤EMT、侵袭、转移等过程,如circLMNB1可抑制E-cadherin的表达,上调N-cadherin的表达,促进结直肠癌细胞发生EMT和体内转移[15]。敲低hsa_circ_0005273可抑制结直肠癌细胞的EMT进程,从而抑制结直肠癌的侵袭、转移[16]。circAPLP2(hsa_circ_0000372)位于11号染色体q24.3,在结直肠癌肝转移患者中表达水平明显升高[17]。Liu等[18]研究发现,敲低结直肠癌细胞SW480中circAPLP2的表达,可上调E-cadherin的表达,下调Vimentin的表达,本研究结果与之一致。Wu等[19]研究发现,circAPLP2竞争性结合miR-101可促进结直肠癌细胞的侵袭和迁移。本研究发现,在结直肠癌细胞中circAPLP2表达水平升高,敲低circAPLP2可抑制结直肠癌细胞的EMT、侵袭和迁移,提示circAPLP2在结直肠癌中发挥了促癌作用。
circRNA通过相同的miRNA识别元件(MRE)竞争性结合miRNA,参与miRNA调控,在肿瘤中发挥作用[20-21]。例如,circ_0001666竞争性结合miR-576-5p可抑制结直肠癌细胞的增殖和侵袭[22],circ_100876竞争性结合miR-516b可促进结直肠癌细胞的增殖、侵袭和EMT过程[23]。本研究发现,circAPLP2竞争性结合miR-497-5p可促进结直肠癌细胞的EMT、侵袭和迁移。miRNA可通过与靶基因3'-UTR MRE配对,调控靶基因的表达水平。FGFR1是一种跨膜蛋白,属于受体酪氨酸激酶,与配体成纤维细胞生长因子(FGF)结合后,可激活下游MAPK/PI3K/Akt、RAS/ERK、STAT3等多条信号通路,调控血管生成、细胞增殖和分化等过程[24]。有研究发现,肿瘤中FGFR1信号通路被异常激活,非小细胞肺癌、乳腺癌、卵巢癌等多种癌症中FGFR1表达水平均升高[25];FGFR1信号通路持续激活导致前列腺癌发生侵袭、转移,同时体内、体外实验均观察到明显的EMT改变[26]。FGFR1可激活ERK1/2-SOX2通路,促进肺癌细胞的EMT、侵袭和迁移[27]。在肺癌中miR-214-3p可通过与FGFR1 3'-UTR MRE配对,抑制FGFR1的表达[28]。在结直肠癌中miR-214水平与FGFR1水平呈负相关,可抑制FGFR1 mRNA和蛋白的表达,促进结直肠癌肝转移[29]。本研究发现,在结直肠癌细胞中FGFR1表达增加,miR-497-5p靶向抑制FGFR1的表达可促进结直肠癌的EMT、侵袭和迁移,此外circAPLP2竞争性结合miR-497-5p可促进FGFR1的表达。
综上所述,本研究结果表明,circAPLP2在结直肠癌细胞中呈高表达,可通过竞争性结合miR-497-5p促进FGFR1的表达,从而促进结直肠癌细胞的侵袭和迁移,这为结直肠癌靶向药物的研发提供了理论依据。但由于缺乏相关动物实验支持,circAPLP2竞争性结合miR-497-5p促进FGFR1表达在结直肠癌荷瘤小鼠中的作用尚不明确,因此,circAPLP2是否可作为结直肠癌的诊断标志物仍需进一步研究。
