目的：探讨体外受精(IVF)周期人卵丘细胞(CCs)中lncRNA ENST00000502521的表达与卵母细胞成熟及胚胎发育的关系,判断其对体外受精-胚胎移植(IVF-ET)结局的预测价值。方法收集40例首次接受长方案超促排卵患者的卵丘细胞,根据卵丘细胞围绕的卵母细胞受精后胚胎发育情况将卵丘细胞分成两组,优质胚胎组和低质胚胎组,采用实时荧光定量逆转录-聚合酶链反应(qRT-PCR)技术检测两组卵丘细胞中 lncRNA ENST00000502521的相对表达量,分析其与胚胎发育及妊娠结局的关系；采用受试者工作特征曲线(ROC)评价 lncRNA ENST00000502521相对表达量对临床妊娠结局的预测价值。结果 IVF 患者低质胚胎组中 ln-cRNA ENST0000050252表达较优质胚胎组明显增高( P <0．05),且未妊娠组 lncRNA ENST00000502521相对表达量较妊娠组增高(P <0．05)；lncRNA ENST00000502521预测妊娠结局的 ROC 曲线下面积(AUC)为0．71(P <0．05,95% CI：0．55~0．87),灵敏度为84．2%,特异性为61．9%。结论lncRNA ENST00000502521可能参与影响卵母细胞成熟及胚胎发育,可作为一个潜在的分子标志物预测胚胎质量和妊娠结局。

Objective To explore the expression of lncRNA ENST00000502521 in human cumulus cells of women undergoing in vitro fertilization (IVF) and the relationship between lncRNA ENST00000502521 and oocyte matura-tion and embryo development. Moreover, its predictive value of IVF outcome was also discussed. Methods The expression of lncRNA ENST00000502521 was measured in 40 pairs of cumulus cells from oocytes resulting in high-quality embryo and from oocytes resulting in poor-quality embryo by real-time quantitative reverse transcriptase-pol-ymerase chain reaction (qRT-PCR), and further associated these data with embryo developmental potential and competence to establish a pregnancy. The predictive value of the lncRNA ENST00000502521 was evaluated using a receiver operating characteristic (ROC) curve. Results Notably elevated lncRNA ENST00000502521 expression levels were observed in the group poor-quality embryo compared to the group high-quality embryo (P < 0. 05). The relative expression levels of lncRNA ENST00000502521 in the non-pregnancy group were significantly higher than those in the pregnancy group (P < 0. 05). The area under the ROC curve(AUC) of lncRNA ENST00000502521 was 0. 71 (P < 0. 05,95% CI: 0. 55 ~ 0. 87) and had a sensitivity of 84. 2% and a specificity of 61. 9% to predict embryo developmental potential. Conclusion The relative expression levels of lncRNA ENST00000502521 may be considered as potential biomarkers to predict embryo developmental competence and IVF outcome.
