ABSTRACT
[Objective]Dysregulated long noncoding RNAs(lncRNAs)have been found involved in human diseases,including cancers. Long non-coding RNA growth arrest-specific 5(GAS5)was reported to be dysregulated in different types of cancers. Howev-er,the role of GAS5 in ovarian cancer remains elusive.[Methods]In the present study,the expression of GAS5 was detected in 108 ovarian cancer tissues and compared adjacent normal tissues by quantitative real-time PCR(qRT-PCR).[Results]The results showed that the expression levels of lncRNA GAS5 were significantly decreased in cancer tissues(P=0.0004),and it was negatively correlated with tumor size(5 cm,P<0.0001),invasion depth(T1-T2 vs. T3-T4,P=0.0021),and tumor grade(Ⅰ~Ⅱgrades vsⅢ~Ⅳgrades,P=0.0086)in ovarian cancer patients. Kaplan-Meier analysis demonstrated that decreased lncRNA GAS5 expression contributed to poor disease-free survival and overall survival.[Conclusion]In conclusion ,our study suggested that decreased lncRNA GAS5 expression may beidentified as a potential poor prognostic biomarker in ovarian cancer.
