Comparison of some circRNA databases
| CircBase | CircNEet | CSCD | CCRDB | |
|---|---|---|---|---|
| Purpose of the study | An integrated circRNAs database of data from the literature. | A public database that provides tissue-specific circRNAs expression profiles and circRNAs–miRNA gene regulatory networks. | A comprehensive cancer-specific circRNAs database | A circRNAs integration database and tools for analysis function. |
| Reference source | CircRNAs in scientific literature. | circRNAs in scientific literature. | CircBASE, circNET and other databases. | Experimental sequencing data and related circRNAs literature data. |
| Analysis function | No | No | No | Yes |
| Discovery of new CircRNAs | No | Yes | No | Yes |
| Innovation point | Integrate several circRNAs data into a standardized database. | CircRNAs is classified by new expression pattern, and new circRNAs is found and named. | Provide the first comprehensive cancer-specific circRNAs database. | Provide new circRNAs discovery and analysis tools to search for candidate target genes. |
