[Abstract]:Objective: to investigate the effect of miRNA-506 on proliferation, invasion and migration of epithelial ovarian cancer cells. The expression of miRNA-506 in epithelial ovarian cancer cell line A2780OES-2Ovar-3 and SK-OV-3 was detected by qRT-PCR, and the epithelial ovarian cancer cell line. 2 was screened out with relatively high expression and relatively low expression of miRNA-506. MiRNA-506 inhibitor plasmid was used to transfect epithelial ovarian cancer cell line with relatively high expression of miRNA-506, and miRNA-506 mimics plasmid was used to transfect epithelial ovarian cancer cell line. 3. The effect of miRNA-506 on proliferation of epithelial ovarian cancer cells was detected by CCK8. 4. 4. The effect of miRNA-506 on invasion and migration of epithelial ovarian cancer cells was detected by Transwell chamber method. The result is 1: 1. In epithelial ovarian cancer cell line A2780 / ES-2Ovar-3 and SK-OV-3, the expression of miRNA-506 in A2780 cell line was the highest and the lowest in SK-OV-3 cell line. The A450 value of epithelial ovarian cancer cell line A2780 transfected with miRNA-506 inhibitor plasmid was 2.3095 鹵0.0117, the A450 value of negative transfection control group was 2.2216 鹵0.0228, the difference was statistically significant (P 0.05), and the A450 value of epithelial ovarian cancer cell line SK-OV-3 transfected with miRNA-506 mimics plasmid was 2.0106 鹵0.0950. The A450 value of the radiation group was 2.1744 鹵0.0436, and the difference was statistically significant (P 0.05). The number of migration cells of epithelial ovarian cancer cell line A2780 transfected with miRNA-506 inhibitor plasmid was 126 鹵10.91, while that of negative control group was 95 鹵11.11.The difference was statistically significant (P0.05). The migration of epithelial ovarian cancer cell line SK-OV-3 transfected with miRNA-506 mimics plasmid was fine. The cell number was 103.2 鹵9.78, and the number of migration cells in negative transfected control group was 121.0 鹵5.61. The difference was statistically significant (P 0.05). The number of invasive cells of epithelial ovarian cancer cell line A2780 transfected with miRNA-506 inhibitor plasmid was 1: 25.0 鹵14.20, while that of negative transfection control group was 16.6 鹵7.89.The difference was not statistically significant (P 0.05). The number of SK-OV-3 cells transfected with miRNA-506 mimics plasmid was 52.4 鹵8.47, while the number of invasive cells in negative transfected control group was 67.2 鹵9.68. The difference was statistically significant (P 0.05). Conclusion 1. In epithelial ovarian cancer cell line, inhibition of miRNA-506 expression promoted the proliferation of A2780 cells, and over-expression of miRNA-506 inhibited the proliferation of SK-OV-3 cells. The results showed that miRNA-506 could inhibit the proliferation of epithelial ovarian cancer cells. In epithelial ovarian cancer cell line, inhibition of miRNA-506 expression promoted the migration of A2780 cells, and over-expression of miRNA-506 inhibited the migration of SK-OV-3 cells. It is suggested that miRNA-506 can inhibit the migration ability of epithelial ovarian cancer cells. In epithelial ovarian cancer cell line, inhibition of miRNA-506 expression promoted the invasion ability of A2780 cells, and overexpression of miRNA-506 inhibited the invasion ability of SK-OV-3 cells. These results suggest that miRNA-506 can inhibit the invasion of epithelial ovarian cancer cells.
