摘  要:目的研究下涮诱骗受体3(DcR3)对爿十癌细胞系HepG2细胞生物学性状的影响。方法培养肝癌细胞系HepG2细胞,将特异性靶向DcR3的小分子干扰RNA(siRNA)转染进入细胞。设立siRNA-1、siRNA-2、siRNA-3、siRNA4、阴性siRNA以及非转染siRNA对照组。应用细胞计数试剂盒实验检测HepG2细胞的增殖能力;划痕实验检测HepG2细胞的运动能力;Matligel和Transwell实验检测HepG2细胞的侵袭和迁移能力,以期明确下调DcR3对HepG2细胞生物学性状的影响。结果siRNA-1组、siRNA-2组、siRNA-3组、siRNA-4组HepG2细胞中DcR3的表达明显低于对照组[(0.167±0.007)、(0.172±0.010)、(0.053±0.016)、(0.176±0.010)比(0.263±0.019)](P〈0.05或P〈0.01)。外源性下调DcR3的表达可以明显抑制HepG2细胞增殖,而转染阴性对照组的HepG2细胞增殖能力无明显降低。在转染24h后,DcR3siRNA组细胞吸光度值与非转染对照组、转染阴性对照组比较明显降低[(0.566±0.024)比(0.621±0.009)、(0.613±0.017)](P〈0.05)。细胞侵袭和迁移实验证实,下调DcR3的表达可以明显降低HepG2细胞的侵袭和迁移能力。结论下调DcR3对肝癌细胞HepG2基因有明显的抑制作用,降低了其增殖、侵袭和转移的能力。Objective To study the effect of down-regulation of decoy receptor 3 (DcR3) on biological characteristics of hepatoma cell line HepG2. Methods DcR3 small interfering RNA(DeR3-siRNA) was transfected into HepG2 cells; 6 cell groups(siRNA-1, siRNA-2, siRNA-3, siRNA-4, negative siRNA and non-siRNA transfection control group) were established for the next experiment. Proliferation ability of HepG2 cells was tested by Cell Counting Kit-8 method; motor ability was tested by scratch adhesion test; invasion and migration abilities were tested by Matrigel ad Transwell test. Results The expression of DcR3 in HepG2 cells with DeR3-siRNA (4 groups) was significantly lower than that in control group[ (0. 167 ± 0. 007), (0. 172 ± 0. 010), (0. 053 ± 0.016),(0.176±0.010) vs (0.263 ±0.019)] (P〈0.05 or P〈0.01). Proliferation of HepG2 cells was inhibited by down-regulation of DcR3 expression. After 24 h of transfection, the absorbance value in DcR3 siRNA HepG2 cells was significantly lower than that in blank control group and negative control group[ (0. 566 ±0. 024) vs ( 0. 621 ± 0. 009 ) , ( 0. 613 ± 0. 017 ) ] ( P 〈 0. 05 ). Invasion and migration abilities of HepG2 cells was inhibited by down-regulation of DcR3 expression. Conclusion Down-regulation of DcR3 has an inhibitive effect on proliferation, invasion and migration abilities of hepatoma HepG2 cells.
