      摘 要:[目的] 研究Annexin A7基因对肿瘤细胞黏附分子表达及其生物学行为的影响。[方法] 采用shRNA干扰技术稳定转染小鼠Hca-P细胞,获得Annexin A7下调表达及Hca-P无关序列细胞株,采用Western Blot、qRT-PCR分别检测Annexin A7对黏附相关分子FAK、Src、E-cadherin等基因及蛋白表达水平的影响,应用淋巴结粘附及Transwell侵袭实验检测Annexin A7下调对Hca-P细胞淋巴结粘附及侵袭能力的干扰。[结果] Annexin A7基因表达下调组细胞的FAK和Src基因及蛋白表达水平较A7无关序列组分别上升1.81倍、1.80倍及1.58倍、1.59倍(P<0.05),E-cadherin基因及蛋白表达水平则分别下降54.11%和54.27%,而上述分子基因与蛋白表达水平在未处理Hca-P组与A7无关序列组间无统计学差异(P>0.05),且在Annexin A7下调后Hca-P细胞的淋巴结粘附及侵袭能力上升,ShRNA-AnnexinA7组淋巴结黏附细胞数(1074±162.8)显著性多于A7无关序列组(234.7±40.08)及Hca-P组(220.3±39.53)(P<0.05),ShRNA- A7细胞组穿过小室的细胞数目(294.8±64.40)明显多于A7无关序列细胞组(79±28.04)及Hca-P细胞组(57.60±25.62)(P<0.05),而Hca-P与无关序列细胞组之间则无统计学差异(P>0.05)。[结论] Annexin A7可通过影响黏附相关分子FAK、Src、E-cadherin等基因与蛋白表达水平从而改变Hca-P细胞生物学行为。
英文摘要:
      Abstract:[Objective] To investigate the effect of Annexin A7 on the expression of adhesion molecules and biological behavior in mouse hepatocarcinoma cells. [Methods] Mouse heparocarcinoma Hca-P cells were transfected with Annexin A7 shRNA(AnnexinA7-shRNA group) or unrelated shRNA(blank control group). The expressions of Annexin A7 and the adhesion molecules FAK,Src,E-cadherin in Hca-P cells were detected by Western Blot and qRT PCR. Transwell assay and lymph node adhesion testing were used to analyze the invasion and adhesion ability of Hca-P cells after Annexin A7 shRNA interference. [Results] Compared with the blank control group,the expression of Annexin A7 was reduced in AnnexinA7-shRNA group(P<0.05); the mRNA and protein expression levels of FAK and Src were increased by 1.81,1.80 times and 1.58,1.59 times(P<0.05),respectively,while the mRNA and protein expression levels of E-cadherin were decreased by 54.11% and 54.27%,respectively(P<0.05). Meanwhile,the invasion and adhesion ability in AnnexinA7- shRNA group was significantly higher than wild Hca–P cells and blank control group,the number of lymph node cells in ShRNA-AnnexinA7 group(1074 ± 162.8) was significantly higher than that in blank control group(234.7 ± 40.08) and wild Hca-P cell group(220.3±39.53)(P<0.05),the number of migrant cells in ShRNA-AnnexinA7 group(294.8±64.40)was significantly higher than that in blank control group(79±28.04) and wild Hca-P cell group(57.60±25.62)(P<0.05),while there was no significant difference between wild Hca-P cell and blank control groups(P>0.05). [Conclusion] Annexin A7 may change biological behavior of hepatocarcinoma Hca-P cells by influencing the gene and protein expression of adhesion molecules FAK,Src and E-cadherin.
