The corneal endothelium maintains corneal transparency; consequently, damage to this endothelium by a number of pathological conditions results in severe vision loss. Publicly available expression databases of human tissues are useful for investigating the pathogenesis of diseases and for developing new therapeutic modalities; however, databases for ocular tissues, and especially the corneal endothelium, are poor. Here, we have generated a transcriptome dataset from the ribosomal RNA-depleted total RNA from the corneal endothelium of eyes from seven Caucasians without ocular diseases. The results of principal component analysis and correlation coefficients (ranged from 0.87 to 0.96) suggested high homogeneity of our RNA-Seq dataset among the samples, as well as sufficient amount and quality. The expression profile of tissue-specific marker genes indicated only limited, if any, contamination by other layers of the cornea, while the Smirnov-Grubbs test confirmed the absence of outlier samples. The dataset presented here should be useful for investigating the function/dysfunction of the cornea, as well as for extended transcriptome analyses integrated with expression data for non-coding RNAs.
角膜内皮维持角膜透明度;因此,许多病理状况对内皮层的损伤会导致严重的视力丧失。公开可用的人类组织表达数据库可用于研究疾病的发病机制和开发新的治疗方法;然而,眼组织,特别是角膜内皮的数据库却很差。在这里,我们从七位无眼部疾病的白种人眼睛的核糖体 RNA 耗尽的总 RNA 中生成了一个转录组数据集。主成分分析和相关系数(范围从 0.87 到 0.96)的结果表明,我们的 RNA-Seq 数据集中样本之间具有很高的同质性,并且具有足够的数量和质量。组织特异性标记基因的表达谱表明,即使有任何污染,也只是局限于角膜的其他层,而 Smirnov-Grubbs 检验则证实不存在异常值样本。这里提供的数据集应该有助于研究角膜的功能/功能障碍,以及与非编码 RNA 的表达数据相结合的扩展转录组分析。
