摘要:

目的 观察果糖二磷酸醛缩酶 C(fructose­bisphosphate aldolase C, ALDOC)在结肠癌组织和细胞中的表达及其对生物学行为的影响。方法 利用GEPIA数据库分析结肠癌组织ALDOC的表达水平。 以患者癌旁组织或正常结肠上皮细胞 FHC 为对照,RT­qPCR 及免疫组化检测结肠癌组织和癌细胞 SW620、SW480、HT­29、HCT­116 中 ALDOC mRNA 和蛋白的表达,并分析 ALDOC mRNA 表达与患者临床病理因素的关系。将结肠癌细胞 SW620 分为对照组、NC inhibitor 组和 ALDOC inhibitor 组;通过 Lipofectamine 2000将ALDOC inhibitor 或阴性对照转染各组SW620细胞;MTT法及癌细胞单克隆形成检测细胞增殖能力; 划痕实验检测细胞迁移能力;Transwell小室实验检测细胞侵袭能力;RT­qPCR检测细胞ALDOC mRNA的表 达;Western blot 检测细胞 ALDOC、金属基质蛋白酶­2/9(MMP­2/9)的表达。结果 GEPIA 数据库显示结肠 癌组织 ALDOC 的表达水平高于正常组织(P < 0.05);与癌旁组织或 FHC 相比,结肠癌组织和细胞 SW620、 SW480、HT­29、HCT­116 中 ALDOC mRNA 和蛋白上调,且 ALDOC mRNA 水平与患者肿瘤分化程度、TNM 分期、淋巴结转移有明显的相关性(P < 0.05);下调 ALDOC mRNA 能够下调 MMP­2、MMP­9 蛋白水平,抑制细胞生长,减少划痕愈合和侵袭细胞数(P < 0.05)。结论 ALDOC 水平在结肠癌组织和细胞中表达上调,且与结肠癌患者的不良预后紧密相关。ALDOC通过调节MMP­2/9调控结肠癌细胞的侵袭和迁移能力。

Abstract:

Objective To observe the expression of fructose ­ bisphosphate aldolase C (ALDOC) in colon cancer tissues and cells and to explore its effect on biological behavior. Methods GEPIA database was used to analyze the expression level of ALDOC in colon cancer tissues. The expression of ALDOC mRNA and protein in colon cancer tissues and cancer cells SW620, SW480, HT­29 and HCT­116 were detected by RT­qPCR and immunohistochemistry,and the relationship between ALDOC mRNA expression and clinicopathological factors was analyzed. Colon cancer cell SW620 was divided into control group, NC inhibitor group and ALDOC inhibitor group. ALDOC inhibitor or negative control was transfected into SW620 cells by lentivirus transfection kit.MTT assay and monoclonal formation of cancer cells were used to detect cell proliferation. Scratch test was used to detect cell migration ability, and transwell chamber test to detect the invasion ability of cells. The expression of ALDOC mRNA was detected by RT­qPCR, and that of ALDOC and MMP­2/9 was detected by western blot. Results GEPIA database showed that the expression level of ALDOC in colon cancer tissues was higher than that in normal tissues (P < 0.05). Compared with those in adjacent tissues or FHC, ALDOC mRNA and protein in colon cancer tissues and cells SW620, SW480, HT­29 and HCT­116 were up­regulated, and ALDOC mRNA level was significantly correlated with tumor differentiation, TNM stage and lymph node metastasis (P < 0.05). Down­regulating ALDOC mRNA could down­regulate MMP­2 and MMP­9 protein levels, inhibit cell growth, and reduce the number of wound healing and invasive cells (P < 0.05). Conclusion ALDOC level is up­regulated in colon cancer tissues and cells, and it is closely related to the poor prognosis of colorectal cancer patients. ALDOC regulates the invasion and migration of colon cancer cells by regulating MMP­2/9.
