摘要
MicroRNA (miRNA) is an abundant class of small non-coding RNAs that act as gene regulators. Recent studies have suggested that miRNA deregulation is associated with the initiation and progression of human cancer. However, information about ovarian cancer-related miRNA is mostly limited to tissue miRNA. The aim of this study was to find specific profiles of plasma-derived miRNAs of ovarian cancer. In this present study, the expression profiles of 740 miRNAs in plasma from 18 patients and 24 healthy women subjects were evaluated using microfluidic based multiplex qRT-PCR. Our results demonstrated that expression levels of eight miRNAs were significantly upregulated in patients with ovarian cancer when compared with a control group (p < 0.05). Expression levels of four miRNAs were found significantly downregulated in patients with ovarian cancer (p < 0.05). In addition, 10 miRNAs were expressed only in the ovarian cancer group and miR-138-5p of these miRNAs is ovarian specific. In conclusion, our study suggests that detecting these ovarian cancer specific miRNAs in plasma might serve as novel non-invasive biomarkers for ovarian cancer.
