144例维吾尔族与汉族女性子宫内膜癌微小RNA表达特点及临床意义
R737.33; 目的:分析144例女性子宫内膜癌微小RNA(microRNA,miRNA)的表达特点,对比其在维吾尔族与汉族女性子宫内膜癌中的表达差异及其与临床病理特点的内在关联性,阐述临床意义.方法:144例维吾尔族与汉族女性(包括62例维吾尔族和82例汉族),采用Taqman低密度芯片对比两者子宫内膜癌miRNA的表达特点,选取5种miRNA,采用实时定量PCR法验证并分析这些miRNA的表达特点.结果:miRNA表达谱分析显示,Ⅱ型癌突出的特点是许多miRNA在一个民族中表达升高或降低,而在另一个民族中不表达或变化轻微.144例女性的子宫内膜癌miR-141、miR-200a、miR-...

Abstract | R737.33; 目的:分析144例女性子宫内膜癌微小RNA(microRNA,miRNA)的表达特点,对比其在维吾尔族与汉族女性子宫内膜癌中的表达差异及其与临床病理特点的内在关联性,阐述临床意义.方法:144例维吾尔族与汉族女性(包括62例维吾尔族和82例汉族),采用Taqman低密度芯片对比两者子宫内膜癌miRNA的表达特点,选取5种miRNA,采用实时定量PCR法验证并分析这些miRNA的表达特点.结果:miRNA表达谱分析显示,Ⅱ型癌突出的特点是许多miRNA在一个民族中表达升高或降低,而在另一个民族中不表达或变化轻微.144例女性的子宫内膜癌miR-141、miR-200a、miR-205表达均升高,维吾尔族女性I型癌miR-141/200a表达升高的肿瘤更具侵袭性,而汉族女性I型癌的特点相反,miR-200a表达升高的肿瘤侵袭性呈减弱趋势,但Ⅱ型癌miR-200a表达升高的肿瘤趋向更具侵袭性.miR-145、miR-143在维吾尔族与汉族女性子宫内膜癌中的表达特点相反,在维吾尔族表达升高,在汉族显著降低(P<0.05).维吾尔族中Ⅱ型癌miR-145、miR-143升高更明显,侵袭性相对弱的肿瘤的miR-145表达水平更高,肌层浸润深度< 1/2组差异有统计学意义(P =0.042).汉族女性I/Ⅱ型癌中miR-145和miR-143的表达均降低,侵袭性强的I型癌中两者降低得更明显,但差异无统计学意义;Ⅱ型癌不具此特点.结论:维吾尔族与汉族女性子宫内膜癌miRNA表达存在一定差异性,miR-141/200a/205在子宫内膜癌中普遍表达升高,但miR-141/200a在维吾尔族与汉族I/Ⅱ型子宫内膜癌中扮演的角色可能不尽相同.miR-145/143在维吾尔族与汉族女性子宫内膜癌中的表达特点相反,但可能均发挥抑癌作用. |
