Objective To investigate the effects of inhibiting KDM2A gene on the proliferation, invasion and migration of liver cancer cells and its possible regulatory mechanism. Methods Forty pairs of HCC tissues and their adjacent normal counterparts were collected from 2014 to 2017 in Tongji Hospital, Tongji Medical College Affiliated to Huazhong University of Science and Technology. Human liver cancer cell lines HepG2, Huh7, HCCLM3, MHCC-97H and normal liver cells LO2 were cultured in vitro. The mRNA and protein expression levels of KDM2A in HCC tissues and cells were detected by qRT-PCR and Western blotting. Huh7 cells were taken and set up as follows: (1) si-NC group (transfected with si-NC) and si-KDM2A group (transfected with si-KDM2A); (2) mimic-NC group (transfected with mimic-NC), miRNA-29a-3p mimic group (transfected with miRNA-29a-3p mimic), inhibitor-NC group (transfected with inhibitor-NC) and miRNA-29a-3p inhibitor group (transfected with miRNA-29a-3p inhibitor). The mRNA and protein expression levels of KDM2A were detected by qRT-PCR and Western blotting. The invasion and migration of cells were detected by Transwell, the proliferation of cells was detected by CCK-8 methods. The online databases TargetScan, miRDIP, miRWalk, Starbase and miRDB were used to predict the binding sites of KDM2A and miR-29a-3p. The KDM2A 3'-UTR (WT) or KDM2A 3'-UTR (MUT) report plasmid was co-transfected with NC-miRNA or miR-29a-3p mimics respectively for 48 h in 293T cells, and the luciferase activity was detected by the luciferase reporter gene detection system. Results Compared with adjacent normal counterparts, the relative mRNA and protein expression levels of KDM2A in HCC tissues increased significantly (P<0.05). Compared with LO2, the relative mRNA and protein expression levels of KDM2A in HepG2, Huh7, HCCLM3 and MHCC-97H increased significantly (P<0.05). Compared with si-NC group, the proliferation, invasion and migration of Huh7 cells in si-KDM2A group decreased significantly (P<0.05 or P<0.01). The analysis results of TargetScan, miRDIP, miRWalk, Starbase and miRDB showed that there were binding sites between KDM2A and miR-29a-3p. The results of the dual luciferase reporter assay showed that miR-29a-3p mimic significantly reduced KDM2A-MUT luciferase activity (P<0.01). After overexpression of miRNA-29a-3p, the relative mRNA and protein expression levels of KDM2A were decreased (P<0.01), the proliferation, invasion and migration abilities were decreased (P<0.05) in Huh7 cells. After inhibiting the expression of miRNA-29a-3p, the relative mRNA and protein expression levels of KDM2A were increased (P<0.05), the proliferation, invasion and migration abilities were enhanced (P<0.05) in Huh7 cells. Conclusion Inhibiting the expression of KDM2A can reduce the proliferation and migration ability of Huh7 cells. miR-29a-3p may be the upstream regulator of KDM2A and participate in the occurrence and development of hepatocellular carcinoma.

目的 探讨抑制KDM2A基因对肝癌细胞增殖、侵袭和迁移的影响及其可能的调控机制。方法 收集2014-2017年华中科技大学同济医学院附属同济医院收治的40例肝细胞癌(HCC)患者的肝癌组织及其癌旁组织,体外培养人肝癌细胞株HepG2、Huh7、HCCLM3、MHCC-97H及正常肝细胞LO2,采用qRT-PCR及Western blotting检测肝癌组织及细胞中KDM2A mRNA及蛋白的表达情况。取Huh7细胞,设置:(1)si-NC组(转染si-NC)与si-KDM2A组(转染si-KDM2A);(2)mimic-NC组(转染mimic-NC)、miRNA-29a-3p mimic组(转染miRNA-29a-3p mimic)、inhibitor-NC组(转染inhibitor-NC)与miRNA-29a-3p inhibitor组(转染miRNA-29a-3p inhibitor)。采用qRT-PCR和Western blotting检测KDM2A mRNA及蛋白的表达情况,CCK-8法检测细胞增殖能力,Transwell实验检测细胞侵袭和迁移能力。采用在线数据库TargetScan、miRDIP、miRWalk、Starbase及miRDB预测KDM2A与miR-29a-3p的结合位点。将KDM2A 3'-UTR(WT)或KDM2A 3'-UTR(MUT)报告质粒分别与NC-miRNA或miR-29a-3p mimic共转染293T细胞48 h后,采用荧光素酶报告实验检测荧光素酶活性。结果 与癌旁组织相比,肝癌组织中KDM2A mRNA和蛋白相对表达水平明显升高(P<0.05);与正常肝细胞LO2相比,肝癌细胞HepG2、Huh7、HCCLM3、MHCC-97H中KDM2A mRNA和蛋白相对表达水平明显升高(P<0.05)。与si-NC组比较,si-KDM2A组Huh7细胞增殖、侵袭和迁移能力明显降低(P<0.05或P<0.01)。在线数据库TargetScan、miRDIP、miRWalk、Starbase及miRDB分析结果显示,miR-29a-3p与KDM2A存在结合位点。双荧光素酶报告实验结果显示,miR-29a-3p mimic可明显降低KDM2A-MUT荧光素酶活性(P<0.01)。过表达miRNA-29a-3p后,Huh7细胞中KDM2A mRNA和蛋白相对表达水平降低(P<0.01),细胞增殖、侵袭和迁移能力下降(P<0.05);抑制miRNA-29a-3p的表达后,Huh7细胞中KDM2A mRNA和蛋白相对表达水平升高(P<0.05),细胞增殖、侵袭和迁移能力增强(P<0.05)。结论 抑制KDM2A的表达可减弱人肝癌细胞Huh7的增殖和转移能力,而miR-29a-3p可能是KDM2A的上游调节因子,可参与肝癌的发生发展。

目的 探讨抑制KDM2A基因对肝癌细胞增殖、侵袭和迁移的影响及其可能的调控机制。方法 收集2014-2017年华中科技大学同济医学院附属同济医院收治的40例肝细胞癌(HCC)患者的肝癌组织及其癌旁组织,体外培养人肝癌细胞株HepG2、Huh7、HCCLM3、MHCC-97H及正常肝细胞LO2,采用qRT-PCR及Western blotting检测肝癌组织及细胞中KDM2A mRNA及蛋白的表达情况。取Huh7细胞,设置:(1)si-NC组(转染si-NC)与si-KDM2A组(转染si-KDM2A);(2)mimic-NC组(转染mimic-NC)、miRNA-29a-3p mimic组(转染miRNA-29a-3p mimic)、inhibitor-NC组(转染inhibitor-NC)与miRNA-29a-3p inhibitor组(转染miRNA-29a-3p inhibitor)。采用qRT-PCR和Western blotting检测KDM2A mRNA及蛋白的表达情况,CCK-8法检测细胞增殖能力,Transwell实验检测细胞侵袭和迁移能力。采用在线数据库TargetScan、miRDIP、miRWalk、Starbase及miRDB预测KDM2A与miR-29a-3p的结合位点。将KDM2A 3'-UTR(WT)或KDM2A 3'-UTR(MUT)报告质粒分别与NC-miRNA或miR-29a-3p mimic共转染293T细胞48 h后,采用荧光素酶报告实验检测荧光素酶活性。结果 与癌旁组织相比,肝癌组织中KDM2A mRNA和蛋白相对表达水平明显升高(P<0.05);与正常肝细胞LO2相比,肝癌细胞HepG2、Huh7、HCCLM3、MHCC-97H中KDM2A mRNA和蛋白相对表达水平明显升高(P<0.05)。与si-NC组比较,si-KDM2A组Huh7细胞增殖、侵袭和迁移能力明显降低(P<0.05或P<0.01)。在线数据库TargetScan、miRDIP、miRWalk、Starbase及miRDB分析结果显示,miR-29a-3p与KDM2A存在结合位点。双荧光素酶报告实验结果显示,miR-29a-3p mimic可明显降低KDM2A-MUT荧光素酶活性(P<0.01)。过表达miRNA-29a-3p后,Huh7细胞中KDM2A mRNA和蛋白相对表达水平降低(P<0.01),细胞增殖、侵袭和迁移能力下降(P<0.05);抑制miRNA-29a-3p的表达后,Huh7细胞中KDM2A mRNA和蛋白相对表达水平升高(P<0.05),细胞增殖、侵袭和迁移能力增强(P<0.05)。结论 抑制KDM2A的表达可减弱人肝癌细胞Huh7的增殖和转移能力,而miR-29a-3p可能是KDM2A的上游调节因子,可参与肝癌的发生发展。

Objective To investigate the effects of inhibiting KDM2A gene on the proliferation, invasion and migration of liver cancer cells and its possible regulatory mechanism. Methods Forty pairs of HCC tissues and their adjacent normal counterparts were collected from 2014 to 2017 in Tongji Hospital, Tongji Medical College Affiliated to Huazhong University of Science and Technology. Human liver cancer cell lines HepG2, Huh7, HCCLM3, MHCC-97H and normal liver cells LO2 were cultured in vitro. The mRNA and protein expression levels of KDM2A in HCC tissues and cells were detected by qRT-PCR and Western blotting. Huh7 cells were taken and set up as follows: (1) si-NC group (transfected with si-NC) and si-KDM2A group (transfected with si-KDM2A); (2) mimic-NC group (transfected with mimic-NC), miRNA-29a-3p mimic group (transfected with miRNA-29a-3p mimic), inhibitor-NC group (transfected with inhibitor-NC) and miRNA-29a-3p inhibitor group (transfected with miRNA-29a-3p inhibitor). The mRNA and protein expression levels of KDM2A were detected by qRT-PCR and Western blotting. The invasion and migration of cells were detected by Transwell, the proliferation of cells was detected by CCK-8 methods. The online databases TargetScan, miRDIP, miRWalk, Starbase and miRDB were used to predict the binding sites of KDM2A and miR-29a-3p. The KDM2A 3'-UTR (WT) or KDM2A 3'-UTR (MUT) report plasmid was co-transfected with NC-miRNA or miR-29a-3p mimics respectively for 48 h in 293T cells, and the luciferase activity was detected by the luciferase reporter gene detection system. Results Compared with adjacent normal counterparts, the relative mRNA and protein expression levels of KDM2A in HCC tissues increased significantly (P<0.05). Compared with LO2, the relative mRNA and protein expression levels of KDM2A in HepG2, Huh7, HCCLM3 and MHCC-97H increased significantly (P<0.05). Compared with si-NC group, the proliferation, invasion and migration of Huh7 cells in si-KDM2A group decreased significantly (P<0.05 or P<0.01). The analysis results of TargetScan, miRDIP, miRWalk, Starbase and miRDB showed that there were binding sites between KDM2A and miR-29a-3p. The results of the dual luciferase reporter assay showed that miR-29a-3p mimic significantly reduced KDM2A-MUT luciferase activity (P<0.01). After overexpression of miRNA-29a-3p, the relative mRNA and protein expression levels of KDM2A were decreased (P<0.01), the proliferation, invasion and migration abilities were decreased (P<0.05) in Huh7 cells. After inhibiting the expression of miRNA-29a-3p, the relative mRNA and protein expression levels of KDM2A were increased (P<0.05), the proliferation, invasion and migration abilities were enhanced (P<0.05) in Huh7 cells. Conclusion Inhibiting the expression of KDM2A can reduce the proliferation and migration ability of Huh7 cells. miR-29a-3p may be the upstream regulator of KDM2A and participate in the occurrence and development of hepatocellular carcinoma.

肝细胞癌(hepatocellular carcinoma,HCC)是全球公认的肝脏恶性肿瘤,占原发性肝癌的90%以上,具有侵袭、转移能力强、预后差的特点[1]。HCC发病率居所有癌症第6位,死亡数居所有癌症第3位[2]。尽管目前的治疗策略在延缓HCC进展方面取得了重要进展,但晚期HCC患者的生存率仍很低[3]。因此,进一步了解HCC发生发展的病理生理机制,并开发更有效的治疗策略显得尤为迫切[4-5]。表观遗传学是在核苷酸序列不发生改变的情况下,研究基因表达的可遗传变化的一门遗传学分支学科。表观遗传修饰主要包括组蛋白修饰、DNA甲基化及核小体重排,在癌症的发生发展过程中发挥着重要作用[6-8]。例如,5-甲基胞嘧啶(5-methylcytosine,5mC)可被TET(ten-eleven translocation)蛋白家族进一步转化为5-羟甲基胞嘧啶(5-hmC),该过程是DNA去甲基化的过程。研究发现,5-hmC在结肠癌和HCC的早期诊断中具有潜在应用价值[9-10]。另有研究发现,甲基化转移酶3(methyltransferase like 3,METTL3)在胃癌组织中表达上调,可作为胃癌患者预后的独立预测因素[11]。Tang等[12]发现,结肠癌组织中组蛋白去甲基化酶UTX表达较正常组织上调,沉默UTX可诱导癌细胞G0/G1期阻滞,抑制肿瘤增殖。因此,UTX可能成为结肠癌的一个很有前景的治疗靶点。KDM2A是一种作用于组蛋白H3K36的赖氨酸特异性去甲基酶,近年来越来越多的研究发现其与肿瘤的发生发展密切相关。有研究发现,在肺癌、胃癌、胶质母细胞瘤等多种肿瘤中KDM2A的表达均明显上调,可能发挥致癌基因的作用[13-15]。然而,KDM2A在HCC中的作用尚不清楚。
MicroRNAs(miRNAs或miRs)在各种组织中均有表达,并与癌症、糖尿病、感染等多种疾病密切相关[16-19]。既往多项研究发现,HCC的发病机制涉及多种miRNAs,这些miRNAs可控制细胞的增殖、侵袭和转移,进而影响HCC的发生发展[20-21]。因此,检测肿瘤组织或血液中miRNAs的表达量对疾病的诊断、治疗和预后具有指导意义。近年来,miR-29a-3p作为一种肿瘤抑制基因一直备受关注,本课题组前期研究表明,其可通过降低Robo1的表达来抑制HCC细胞的增殖和转移[22]。KDM2A作为一种表观遗传调控因子,其表达和生物学功能受到多种外界因素的影响[23]。研究表明,在胃癌及胶质母细胞瘤发病过程中,miR-663a、LINC00460、microRNA‑3666和microRNA-29b可直接与KDM2A的启动子结合,调控KDM2A的表达[14-15,24-25]。然而,KDM2A在HCC发生发展中的作用及其机制研究较少。基于KDM2A在核心组蛋白翻译后修饰中的重要作用,本研究探索抑制KDM2A对肝癌细胞增殖、侵袭和迁移的影响,以期为HCC发生发展的分子机制提供理论依据。

CCK-8法检测结果显示,转染miR-29a-3p mimic及mimic-NC 24 h后,两组Huh7细胞增殖能力差异无统计学意义(P>0.05);转染48 h和72 h后,与mimic-NC组比较,miR-29a-3p mimic组Huh7细胞增殖能力明显下降(P<0.01,P<0.001)。相反,与inhibitor-NC组比较,转染24 h、48 h和72 h后,miR-29a-3p inhibitor组Huh7细胞增殖能力明显增强(P<0.05,图5A)。
Transwell实验结果显示,与mimic-NC组比较,miR-29a-3p mimic组Huh7细胞侵袭和迁移能力明显降低(P<0.05);抑制miR-29a-3p的表达后,Huh7细胞侵袭和迁移能力明显增强(P<0.01,图5B、C)。
HCC是全球范围内主要的癌症相关死亡原因之一。80%~90%的HCC患者合并慢性肝炎和肝硬化疾病,HCC的危险因素十分复杂,其中最主要的是乙型、丙型肝炎病毒感染[26-28]。HCC病死率高的主要原因为缺少可靠的早期检测手段,大多数HCC患者在晚期阶段才被诊断,此时患者的预后往往较差。此外,尽管针对HCC的治疗已经取得了很大进展,如手术和化疗,但部分患者仍表现为预后不良和高转移倾向[29]。因此目前仍需要寻找特异性的生物标志物来提高早期HCC的检测,评估预后和预测治疗反应。
KDM2A是一种可作用于H3K36的赖氨酸脱甲基酶,与基因表达的激活或抑制有关[30]。近年来研究发现,KDM2A在肿瘤发生发展中的作用复杂且呈现出组织特异性。Frescas等[31]使用Oncomine在线数据库比较分析了KDM2A在前列腺癌组织和匹配的非肿瘤组织中的差异表达,发现与正常前列腺组织相比,KDM2A在前列腺癌组织中的表达降低。Lu等[32]发现,KDM2A在膀胱癌中表达水平升高,且可通过沉默下游基因RARRES3促进膀胱癌的发生发展。Chen等[33]研究发现,KDM2A在乳腺癌中呈高表达,且可通过抑制DNA去甲基化酶TET2的表达而增加DNA甲基化。Huang等[34]发现,KDM2A可增强胃癌细胞的生长和转移能力。另外,Wang等[35]发现,KDM2A在食管鳞状细胞癌(esophageal squamous cell carcinoma,ESCC)中发挥致癌作用,并在ESCC细胞中高表达,然而,利用RNA测序分析KDM2A控制的基因表达网络时发现,KDM2A不仅可诱导某些致癌基因的表达,如IL6LAT2,同时又可抑制某些致癌基因的表达,如MAT2AHMGCS1。目前,有关KDM2A在HCC中的研究仍较少。本研究发现,KDM2A在肝癌细胞及组织中高表达,抑制KDM2A的表达可抑制肝癌细胞的增殖、转移及侵袭,进而抑制HCC的发生发展。
非编码RNA是缺乏编码蛋白质或多肽的序列,包括小型非编码RNA(20~30个碱基)和长链非编码RNA(大于200个碱基)。MicroRNAs是一种小型非编码RNA,在干细胞维持、增殖、凋亡、代谢、生长及发育等生命过程中发挥着重要作用,其表达异常与多种疾病密切相关,包括病毒感染、心血管疾病和癌症等[36-37]。研究表明,miRNAs是癌症诊断和预后的潜在生物标志物,也是肿瘤治疗的有效靶点[38]。目前,已有多项研究报道HCC中存在多种差异表达的microRNAs,可能参与HCC的发生发展[39-41]。既往研究表明,miR-29a-3p可通过上调Robo1的表达,激活PI3K/Akt/mTOR信号通路,从而影响HCC的发生发展[22]。本研究通过双荧光素酶实验验证了在肝癌细胞中KDM2A受到miR-29a-3p的调控。
综上所述,本研究结果表明,KDM2A在HCC中高表达,抑制KDM2A的表达后,Huh7细胞的增殖、侵袭和迁移能力减弱,并且可被miR-29a-3p靶向调控。这为HCC靶向药物研发提供了理论依据,但由于缺乏相关动物实验支持,所以,抑制KDM2A表达在HCC荷瘤小鼠中的作用尚不明确。KDM2A是否可作为HCC的诊断标志物及治疗靶点仍需进一步研究。此外,KDM2A基因有两个可替换的剪接变体长亚型(21个外显子)和短亚型(10个外显子)。有研究表明,KDM2A(长亚型)过表达可抑制HT-29结肠癌细胞的增殖和克隆形成,相反,在肺癌和胃癌细胞中,过表达KDM2A可促进肿瘤的发生发展[42]。KDM2A的不同亚型可能是其在不同细胞模型中发挥作用的关键。在HCC中发挥作用的KDM2A亚型及调控机制仍需进一步探究。
