ABSTRACT
@#[Abstract] Objective: To investigate the effects of plasma-cytoma variant translocation gene 1 (PVT1) on proliferation, migration and invasion of ovarian cancer SKOV3 cells. Methods: Quantitative reverse transcription PCR (qRT-PCR) was used to detect the expression of PVT1 in 32 pairs of ovarian cancer tissues and corresponding para-carcinoma tissues. The effects of PVT1 on proliferation, migration and invasion of ovarian cancer cells were studied by CCK-8, scratch wound healing assay and Transwell assay. Results: The expression level of PVT1 in SKOV3 cells and ovarian cancer tissues was significantly increased (all P<0.01). The expression level of PVT1 was correlated with histological grade, FIGO stage and lymph node metastasis in patients with ovarian cancer (P<0.05 or P< 0.01).After transfection with PVT1 siRNAfor 36, 48 h, expression of PVT1 was significantly decreased in SKOV3 cells; and the inhibition of PVT1 expression could decrease the proliferation ability and inhibit the migration and invasion of SKOV3 cells (P<0.05 or 0.01). Conclusion: LncRNA PVT1 was highly expressed in ovarian cancer. Down-regulation of PVT1 could inhibit the proliferation, migration and invasion of ovarian cancer SKOV3 cells.
