The role of microRNAs in ovarian cancer initiation and progression

摘要

Epithelial ovarian cancer (EOC) has the highest mortality rate of all gynaecological cancers. One of the greatest impediments to improving outcome is an incomplete understanding of the molecular underpinnings of EOC pathogenesis and progression. Recent studies suggest that microRNAs (miRNAs) are involved in ovarian tumorigenesis and cancer development. Several miRNA profiling studies have identified some consensus aberrantly expressed miRNAs in EOC tissues, and these EOC-related miRNAs may play critical roles in the pathogenesis and progression of EOC. Moreover, some of the miRNAs may have diagnostic or prognostic significance. In this review, recent progress to reveal the role of miRNAs in EOC will be addressed, and a model for miRNA functions in ovarian cancer initiation and progression will be proposed.
