miRBase Tracker: keeping track of microRNA annotation changes

Area of Science:

• Bioinformatics
• Genomics
• Molecular Biology

Background:

• miRBase is the primary repository for microRNA (miRNA) annotation data.
• Over time, miRBase has evolved, introducing changes in miRNA naming, sequences, and records.
• These dynamic changes complicate the interpretation and comparison of miRNA research findings.

Purpose of the Study:

• To address the ambiguity caused by evolving miRBase annotations.
• To provide researchers with a tool to track historical and current miRNA annotation data.
• To enhance the accuracy and transparency of microRNA research.

Main Methods:

• Development of miRBase Tracker, an online database.
• Implementation of functionalities to track historical and current miRBase annotations.
• Assessment of the impact of ignoring miRNA sequence annotation changes.

Main Results:

• miRBase annotation changes lead to significant ambiguity in the scientific literature.
• miRBase Tracker successfully tracks historical and current miRNA annotation data.
• The tool facilitates reannotation of analytical platforms and linking of published results to current miRBase standards.

Conclusions:

• miRBase Tracker enhances transparency and accuracy in microRNA research.
• The database helps researchers navigate the complexities of evolving miRNA annotation.
• Consistent and accurate miRNA annotation is crucial for reliable data interpretation and integration.
