-
摘要:
目的 探讨长链非编码RNA HOX转录反义RNA(HOTAIR)在卵巢癌组织与正常卵巢组织中的表达差异。 方法 对44例卵巢癌组织及14例正常卵巢组织样本采用实时荧光定量PCR(RT-PCR)方法检测长链非编码RNA HOTAIR mRNA的表达。 结果 卵巢癌组织中HOTAIR mRNA表达高于正常卵巢组织[(1.26±0.27) vs. (0.14±0.09)],差异有统计学意义(P<0.05),病理类型为低度分化及未分化的卵巢癌组织中HOTAIR mRNA表达高于中-低、中-高及高度分化组织[(1.65±0.41) vs. (0.39±0.14)],差异有统计学意义(P<0.05)。 结论 卵巢癌组织中HOTAIR的表达增高,且癌组织分化越低,HOTAIR表达越高。提示HOTAIR有可能作为发现卵巢癌,并判断其恶性程度的一个分子标志。

Abstract:Objective To investigate the long non-coding RNA HOTAIR (long non-coding HOX antisense intergenic RNA) by examining HOTAIR expression levels in ovarian cancer tissue and normal ovarian tissue. Methods The mRNA of long non-coding RNA HOTAIR expressions were detected by real-time fluorescence quantitative PCR in ovarian cancer (44) and normal ovary tissues (14). Results The expression of HOTAIR in ovarian cancer tissue was higher than that in normal ovarian tissue (1.26±0.27 vs. 0.14±0.09, P<0.05). The expression was statistically higher in poorly differentiated ovarian cancer than poorly-moderately, moderately-well, and well-differentiated ones (1.65±0.41 vs. 0.39±0.14, P<0.05). Conclusion RNA HOTAIR expressions were higher in ovarian cancer; it may play a role in ovarian cancer, and become a biomarker for malignant degree of ovarian cancer and may provide a novel therapeutic target for ovarian cancer.
