| Research Abstract |
The aim of this study was to identify the microRNA marker of the complete hydatidiform moles(CHMs) in plasma. By next generation sequencing and quantitative RT-PCR analysis, hsa-miR-520f, 520b, 520c-3p and 519b-3p were selected as candidate CHMs-associated microRNAs. The median plasma concentration of cell-free has-miR-520f in CHMs pregnancy was significantly higher than in normal pregnancy(27, 194 copies/ mL vs 13, 118 copies/ mL, Mann-Whitney U test, P=0. 002). In 15 cases of CHMs pregnancy, the plasma concentration of cell-free has-miR-520f after termination of pregnancy was significantly decreased than that before termination of pregnancy(wilcoxon signed rank test, P<0. 001). In conclusion, the hsa-miR-520f is CHMs-related microRNA and its plasma concentration may be possible molecular marker of complete hydatidiform mole.
