miRCancer : microRNA Cancer Association Database

Your Image miRCancer provides comprehensive collection of microRNA (miRNA) expression profiles in various human cancers which are automatically extracted from published literatures in PubMed. It utilizes text mining techniques for information collection. Manual revision is applied after auto-extraction to provide 100% precision.

User can search the database by miRNA and/or cancer names in the miRCancer Search page. Our website also provides two sequence analysis tools: clustering and chi-square analysis which can perform analysis on all or selected pool of miRNA sequences.
