A curated ncRNAomics knowledgebase for bridging basic and clinical research in eye diseases.

Introduction for Nc2Eye

Eye diseases (EDs) represent the disorders affecting visual system, such as retinoblastoma, diabetic retinopathy, etc. Non-coding RNAs (ncRNAs), as a large category of functional RNA molecules, have been reported to play a crucial role in EDs. Here, we developed the Nc2Eye database, which contains 7088 experimentally validated ncRNA-ED associations. It covers 4363 ncRNAs involved in 104 kinds of EDs across 8 species through a comprehensive review of more than 2400 published papers. Nc2Eye also gathered 91 high-throughput transcriptome datasets in EDs and normal controls.
