微小核糖核酸与消化道肿瘤的关系

摘要

MicroRNA (miRNA) are species of small noncoding single-stranded RNA with the lengths around 22 nu-rncleotides. The recently study found that miRNA has close relationship with digestive system tumors and can be used as arnpotential tumor marker. In this review, we summarized the latest researches about the role of miRNA in the digestivernsystem tumors.%微小核糖核酸(microRNA,miRNA)是一类长度约为22个核苷酸的单链小分子核糖核酸.最近研究发现,miRNA与消化系统肿瘤的发生有密切的关系,是潜在的肿瘤标记物.本文就近年来miRNA在消化系统肿瘤中的作用作一综述.
