摘要: 目的: 探讨毛茛总苷对肝癌细胞增殖、迁移、侵袭的影响及其对circ_0079593/miR-324-5p通路的调控作用。
方法: 体外培养人肝癌细胞MHCC97H,并分为对照组,毛茛总苷低、中、高剂量组,si-NC组,si-circ_0079593组,毛茛总苷+pcDNA组,毛茛总苷+pcDNA-circ_0079593组;采用CCK-8法、Transwell实验分别检测细胞活力、迁移及侵袭;采用定量反转录聚合酶链反应(quantitative reverse transcription polymerase chain reaction, qRT-PCR)检测circ_0079593和miR-324-5p的表达水平;采用双荧光素酶报告基因实验检测circ_0079593和miR-324-5p的靶向关系;采用蛋白质印迹法检测基质金属蛋白酶-2(matrix metalloproteinase-2, MMP-2)、基质金属蛋白酶-9(matrix metalloproteinase-9, MMP-9)的表达水平。
结果: 与对照组比较,毛茛总苷不同剂量组细胞增殖抑制率和miR-324-5p表达水平均升高(P<0.05),迁移及侵袭细胞数均减少(P<0.05),circ_0079593表达水平及MMP-2、MMP-9蛋白水平均降低(P<0.05),且呈剂量依赖性;circ_0079593能靶向调控miR-324-5p;与si-NC组比较,si-circ_0079593组细胞增殖抑制率升高(P<0.05),迁移及侵袭细胞数均减少(P<0.05),MMP-2、MMP-9蛋白水平均降低(P<0.05);与毛茛总苷+pcDNA组比较,毛茛总苷+pcDNA-circ_0079593组细胞增殖抑制率降低(P<0.05),迁移及侵袭细胞数均增多(P<0.05),MMP-2、MMP-9蛋白水平均升高(P<0.05)。
结论: 毛茛总苷可通过调控circ_0079593/miR-324-5p通路降低肝癌细胞增殖、迁移及侵袭能力。

Abstract: Objective:To explore the effect of total glycosides of ranunculus japonicus on the proliferation, migration and invasion of liver cancer MHCC97H cells and its regulation of circ_0079593/miR-324-5p pathway.
Method:Human hepatocarcinoma cells MHCC97H were cultured in vitro, experimental groups: control group, total glycosides of ranunculus japonicus low-dose group, total glycosides of ranunculus japonicus medium-dose group, total glycosides of ranunculus japonicus high-dose group, si-NC group, si-circ_0079593 group, total glycosides of ranunculus japonicus+pcDNA group, total glycosides of ranunculus japonicus+pcDNA-circ_0079593 group. CCK-8 and Transwell chamber experiments were used to detect cell viability, migration and invasion. The quantitative reverse transcription polymerase chain reaction (qRT-PCR) method was used to detect the expression of circ_0079593 and miR-324-5p. The dual luciferase reporter gene experiment was used to detect the targeting relationship between circ_0079593 and miR-324-5p. Western blotting was used to detect the protein expression of matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9).
Result:Compared with the control group, the cell proliferation inhibition rate and the expression level of miR-324-5p in different dose groups of total glycosides of ranunculus japonicus were increased (P<0.05), while the number of migrating and invading cells was decreased (P<0.05), and the expression level of circ_0079593 and the protein levels of MMP-2, MMP-9 were decreased (P<0.05), and were dose-dependent. circ_0079593 could target and regulate miR-324-5p. Compared with the si-NC group, the cell proliferation inhibition rate in the si-circ_0079593 group was increased (P<0.05), while the number of migrating and invading cells was decreased (P<0.05), and the protein levels of MMP-2 and MMP-9 were decreased (P<0.05). Compared with the total ranunculus glycosides+pcDNA group, the inhibition rate of cell proliferation in the total ranunculus glycosides+pcDNA-circ_0079593 group was reduced (P<0.05), while the number of migration and invasion cells was increased (P<0.05), and the protein levels of MMP-2, MMP-9 were increased (P<0.05).
Conclusion:Total glycosides of ranunculus japonicus could reduce the proliferation, migration and invasion of liver cancer cells by regulating the circ_0079593/miR-324-5p pathway.
