OBJECTIVE: Ovarian cancer is one of the leading causes of cancer-related death in women, but treatment remained unsatisfactory. Studies have shown that lncRNA colon cancer-associated transcript 1 (CCAT1) plays an important regulatory role in different cancers, but its role in ovarian cancer remained largely unclear.

PATIENTS AND METHODS: Quantitative Real-time polymerase chain reaction (qRT-PCR) was applied to detect the expression of lncRNA CCAT1 in ovarian cancer and adjacent tissue, and analysis was applied to explore the relationship between expression and clinical characteristic. After lncRNA CCAT1 suppression, Cell Counting Kit-8 (CCK8) and wound-healing assay were used to detect the proliferation and metastasis ability of ovarian cancer, respectively.

RESULTS: qRT-PCR showed that lncRNA CCAT1 was highly expressed in ovarian cancer tissue, compared with adjacent tissue. Moreover, we found that the expression of lncRNA CCAT1 was closely related to prognosis, tumor size, and lymph node metastasis. We also found that lncRNA CCAT1 could sponge miR-1290 in ovarian cancer.

CONCLUSIONS: In this study, we found that lncRNA CCAT1 could sponge miR-1290 in ovarian cancer, and was closely related to prognosis, proliferation, and metastasis.
