摘要
微小RNA(miRNA)在多数肿瘤中存在异常表达,能在转录后水平调控靶基因的表达,发挥促进或抑制肿瘤浸润转移的作用,其自身的表达也受表观遗传学静息等多种机制的调节。miRNA作为一种理想的标记物,有望成为临床肿瘤治疗的新靶点。
MicroRNA(miRNA) is expressed in most malignant tumors. MiRNA plays important roles in promoting or inhibiting tumor invasion and metastasis through regulating specific gene expression posttranscriptionlly. Deregulation of miRNA can be attributed to multiple mechanisms, such as epigenetic silencing. As an ideal biomarker, miRNA might be a useful therapeutic target in treatment of malignancies clinically.
