OBJECTIVE: Ovarian cancer is the most common fatal gynecologic malignancy in females all over the world. Recently, long noncoding RNAs (lncRNAs) have been reported to exert pivotal functions in tumorigenesis. In this research, lncRNA SNHG14 was studied to identify its role in the metastasis of ovarian cancer.

PATIENTS AND METHODS: SNHG14 expression was detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) in ovarian cancer specimens. Functional assays including wound healing assay, transwell assay, and Matrigel assay were performed to detect the effect of SNHG14 on the migration and invasion of ovarian cancer cells. In addition, the underlying mechanism was further explored through qRT-PCR and Western blot assay.

RESULTS: SNHG14 level was dramatically higher in ovarian cancer specimens. Moreover, cell migration and invasion were significantly attenuated via the inhibition of SNHG14, while enhanced via the SNHG14 overexpression. Besides, the expression of DGCR8 mRNA and protein was markedly downregulated after the knockdown of SNHG14, while upregulated after SNHG14 overexpression. Furthermore, the expression level of DGCR8 was increased in cancer tissues and positively related to the expression of SNHG14 in ovarian cancer tissues.

CONCLUSIONS: In summary, SNHG14 could enhance cell migration and invasion via upregulating DGCR8 in ovarian cancer.
