摘要 目的研究miR-93在结肠癌组织中的表达与临床病理特征的关系,并探讨其对结肠癌细胞的增殖及细胞周期的影响。方法收集108例结肠癌患者的癌组织及癌旁组织,应用原位杂交和荧光定量PCR检测结肠癌组织及癌旁组织中miR-93的表达水平,分析miR-93表达与结肠癌临床病理特征之间的关系。采用反义miR-93转染降低结肠癌细胞SW480和LoVo中miR-93的表达,采用MTT比色法检测结肠癌细胞增殖的变化情况,利用流式细胞仪检测结肠癌细胞周期的变化情况。结果原位杂交检测显示,结肠癌组织miR-93阳性表达率高于癌旁组织(P<0.05);荧光定量PCR检测显示,61.11%(66/108)的结肠癌组织miR-93表达明显高于癌旁组织(P<0.05);随着结肠癌临床分期的进展,miR-93的表达量逐渐升高,临床Ⅲ/Ⅳ期、Ⅰ/Ⅱ期结肠癌miR-93的表达与癌旁组织相比都显著增高(P<0.05);有淋巴结转移的结肠癌患者的miR-93的表达比无淋巴结转移者显著增加(P<0.05);反义miR-93转染结肠癌细胞SW480和LoVo后,miR-93的表达明显降低,SW480和LoVo结肠癌细胞生长受到明显抑制,其生长主要停滞在G0/G1期,而S期和G2/M期细胞的比例下降。结论 miR-93与结肠癌的发生发展密切相关,其可以通过调节细胞周期中G1/S期的转换而影响结肠癌细胞的生长,为结肠癌治疗提供新的靶点。
