Expression and significance of CDCA3 in epithelial ovarian cancer
To investigate the expression of cell division cycle associated protein 3 (CDCA3) in epithelial ovarian cancer and its effect on the proliferation, invasion and migration of cancer cells.
Methods
2
The ovarian cancer tissue of 50 patients and the normal ovarian tissue of 30 patients who underwent surgical resection in our hospital were collected, and A2780, Hey, CAOV3, SKOV3 cells were selected for research. RT-PCR was used to detect the expression level of CDCA3 mRNA in tissues and cells, and Western blot was used to detect the expression level of CDCA3 protein in tissues and cells. CAOV3 cells were divided into the silence group and the Control group, the silence group was transfected with CDCA3 siRNA, while the Control group was transfected with negative control sequence. Hey cells were divided into the overexpression group and the control group, the overexpression group was infected with CAOV3 lentivirus, and the control group was infected with empty vector lentivirus. Cell viability was detected by CCK-8; and the cell invasion and migration were detected by Transwell assay.
Results
2
Compared with normal ovarian tissue, the expression levels of CDCA3 mRNA and CDCA3 protein in epithelial ovarian cancer tissue were higher (
P
<
0.05). Among the epithelial ovarian cancer cell lines A2780, Hey, CAOV3, and SKOV3, the expression levels of CAOV3 mRNA and CDCA3 protein were the highest, while the expression levels of Hey were the lowest. After CDCA3 was silenced, the expression level of CDCA3 protein, cell proliferation activity, invasive and migration ability of CAOV3 cells decreased (
P
<
0.05), the expression levels of Cyclin D1 and MMP-9 protein decreased (
P
<
0.05), while the expression level of E-cadherin protein increased (
P
<
0.05). After CDCA3 was overexpressed, the expression level of CDCA3 protein, cell proliferation activity, invasive and migration ability of Hey cells increased (
P
<
0.05), the expression levels of Cyclin D1 and MMP-9 protein increased (
P
<
0.05), while the expression level of E-cadherin protein decreased (
P
<
0.05).
Conclusion
2
CDCA3 is highly expressed in epithelial ovarian cancer and can promote the proliferation, invasion and migration of epithelial ovarian cancer cells.
