Abstract:
[Abstract] Objective: To investigate the expression and clinical significance of lncRNAANRIL in glioma tissues. Methods: 129 cases of glioma tissues and 25 cases of normal brain tissues as control were collected from patients treated in Sichuan Provincial People’ s Hospital from January 01, 2012 to December 30, 2016. Real-time quantitative PCR was used to detect the mRNA expression of lncRNAANRIL; and the relationship between lncRNAANRIL expression and sensitivity of patients to temozolomide as well as the clinical prognosis of glioma patients were analyzed. Results: Compared with control group, the expression of lncRNAANRIL in 129 cases of glioma tissues was significantly increased ([8.730±0.336] vs [1.090±0.137], t=9.957, P<0.01). The expression of lncRNAANRIL in WHO Ⅰ-Ⅱ grade patients was significantly lower than that of patients at grade Ⅲ-Ⅳ ([4.198±0.260] vs [10.550±0.291], t=13.03, P< 0.01). lncRNA ANRIL expression was significantly correlated with WHO stage，the sensitivity to temozolomide（TMZ）and survival status（all P<0.05）, but not associated with gender, age, KPS score and tumor size (all P>0.05). Moreover, Kaplan-Meier analysis demonstrated that decreased lncRNAANRIL expression contributed to significantly longer overall survival ([29.17±0.64] vs [13.54±0.74] months, P<0.01) and recurrence-free survival time ([9.08±0.56] vs [15.88±0.83] months, P<0.01). Univariate and multivariate analysis also indicated that lncRNAANRIL expression, WHO stage and chemosensitivity could be independent prognostic markers for glioma (P<0.05). Conclusion: Higher pathological grade of glioma patients indicates higher lncRNA ANRIL expression and shorter survival time. lncRNAANRIL is involved in the occurrence and development of glioma, and can be used as a molecular marker for the diagnosis and prognosis of glioma.
