Abstract

BACKGROUND

Long non-coding RNAs (lncRNAs) are characterized as having 200 nucleotides or more and not coding any protein, and several been identified as differentially expressed in several human malignancies, including breast cancer.

METHODS

Here, we evaluated lncRNAs differentially expressed in triple-negative breast cancer (TNBC) from a cDNA microarray data set obtained in a previous study from our group. Using in silico analyses in combination with a review of the current literature, we identify three lncRNAs as potential prognostic factors for TNBC patients.

RESULTS

We found that the expression of WDFY3-AS2, BDNF-AS, and AFAP1-AS1 was associated with poor survival in patients with TNBCs. WDFY3-AS2 and BDNF-AS are lncRNAs known to play an important role in tumor suppression of different types of cancer, while AFAP1-AS1 exerts oncogenic activity.

CONCLUSION

Our findings provided evidence that WDFY3-AS2, BDNF-AS, and AFAP1-AS1 may be potential prognostic factors in TNBC development.

摘要

背景

长链非编码 RNA（lncRNA）的特征是具有 200 个核苷酸或更多，并且不编码任何蛋白质，并且已经在几种人类恶性肿瘤中，包括乳腺癌中鉴定出几种差异表达的 lncRNA。

方法

在这里，我们从我们之前的研究中获得的 cDNA 微阵列数据集评估了三阴性乳腺癌（TNBC）中差异表达的 lncRNA。我们使用计算机分析结合当前文献综述，确定了三个 lncRNA 作为 TNBC 患者的潜在预后因素。

结果

我们发现 WDFY3-AS2、BDNF-AS 和 AFAP1-AS1 的表达与 TNBC 患者的不良生存相关。WDFY3-AS2 和 BDNF-AS 是已知在不同类型的癌症中发挥肿瘤抑制作用的 lncRNA，而 AFAP1-AS1 则发挥致癌活性。

结论

我们的研究结果提供了证据，表明 WDFY3-AS2、BDNF-AS 和 AFAP1-AS1 可能是 TNBC 发展的潜在预后因素。
