We aimed to examine the importance of an lncRNA, namely LINC00852, in the pathogenesis of breast cancer.
In the current study, we used several online tools to examine the importance of LINC00852 in breast cancer. Then, we examined these findings in 50 pairs of breast cancer tissues and adjacent non-cancerous ones. We also re-evaluated the data of miR-145-5p signature from our recent study.
While in silico tools revealed down-regulation of LINC00852 in breast cancer samples, expression assays showed significant up-regulation of this lncRNAs in breast cancer samples compared with matching control samples from Iranian patients. miR-145-5p was under-expressed in breast cancer samples compared with non-cancerous samples. LINC00852 could separate breast cancer tissues from adjacent non-malignant tissues with an AUC value of 0.7218 (P value < 0.001).
The current study potentiates LINC00852/miR-145-5p axis as a possible contributor to the pathogenesis of breast cancer.
我们旨在研究一种长链非编码RNA（lncRNA），即LINC00852在乳腺癌发病机制中的重要性。
在本研究中，我们使用了几种在线工具来研究LINC00852在乳腺癌中的重要性。然后，我们在50对乳腺癌组织和相邻的非癌组织中验证了这些发现。我们还重新评估了我们最近研究中的miR-145-5p特征数据。
虽然计算机模拟工具显示乳腺癌样本中LINC00852表达下调，但表达分析显示，与来自伊朗患者的匹配对照样本相比，该lncRNA在乳腺癌样本中显著上调。与非癌样本相比，miR-145-5p在乳腺癌样本中表达不足。LINC00852能够将乳腺癌组织与相邻的非恶性组织区分开来，曲线下面积（AUC）值为0.7218（P值<0.001）。
本研究增强了LINC00852/miR-145-5p轴作为乳腺癌发病机制可能因素的作用。
