Diabetes causes the dysregulation of several organs, and these effects are often closely associated with changes in the expression of long non-coding RNAs (lncRNAs), a group of non-coding RNAs, within these tissues. Previous studies have described a variety of changes in the expression profile of several lncRNAs from different organs in response to the pathogenesis of diabetes. However, none of these studies compared the expression profiles of these lncRNAs between these organs. This study was designed to identify common and specific lncRNAs involved in the progression of diabetes in the skeletal muscles and kidneys.
Publicly available RNA sequencing data of diabetic patients was obtained from the Gene Expression Omnibus database. By analyzing the expression of lncRNAs in these datasets, differentially expressed lncRNAs in each tissue between non-diabetic and diabetic patients were identified. To identify any lncRNAs changed in common in both kidney and muscle tissues, those lncRNAs that are significantly dysregulated in both datasets were selected.
These evaluations identified a series of novel lncRNAs unique to each organ and several transcripts that were common to both skeletal muscle and kidney tissues in these patients. Interestingly, the genomic location of these lncRNAs suggests that they reside in close proximity to several protein-coding genes known to be related to diabetes suggesting that these lncRNAs may have a regulatory relationship with their neighboring genes.
These results offer valuable insights into the role of lncRNAs during the pathogenesis of diabetes.
糖尿病导致多个器官的失调,这些影响通常与这些组织内长链非编码 RNA(lncRNA)表达的变化密切相关,lncRNA 是一组非编码 RNA。先前的研究已经描述了不同器官的多种 lncRNA 表达谱在糖尿病发病机制中的变化。然而,这些研究都没有比较这些器官之间这些 lncRNA 的表达谱。本研究旨在鉴定骨骼肌和肾脏中参与糖尿病进展的常见和特异性 lncRNA。
从基因表达综合数据库中获取了糖尿病患者的公开 RNA 测序数据。通过分析这些数据集的 lncRNA 表达情况,鉴定出每个组织中非糖尿病患者和糖尿病患者之间差异表达的 lncRNA。为了鉴定在肾脏和肌肉组织中均发生变化的 lncRNA,选择在两个数据集都显著失调的 lncRNA。
这些评估鉴定了一系列每个器官特有的新型 lncRNA,以及几个在这些患者的骨骼肌和肾脏组织中都常见的转录本。有趣的是,这些 lncRNA 的基因组位置表明它们位于与糖尿病相关的几个已知蛋白编码基因的附近,这表明这些 lncRNA 可能与它们的相邻基因具有调节关系。
这些结果为 lncRNA 在糖尿病发病机制中的作用提供了有价值的见解。
