MicroRNA Discovery & Analysis by High-Throughput Sequencing

Filed Under Information | Leave a Comment

For profiling microRNA expression, microarrays have been the standard technology. However, the recent introduction of deep sequencing technology, enabling the simultaneous sequencing of up to millions of DNA or RNA molecules, has provided another option for profiling microRNAs. Deep sequencing utilizes massively parallel sequencing, generating millions of small RNA sequence reads from a given sample. Profiling of microRNAs by deep sequencing measures absolute abundance and allows for the discovery of novel microRNAs that have eluded previous cloning and standard sequencing efforts.[1]

There are many web-based tools available for handling microRNA deep sequencing data:

mirTools – a web server for microRNA profiling and discovery based on high-throughput sequencing data.

miRDeep – Discovering known and novel miRNAs from deep sequencing data

deepBase – a database for deeply annotating and mining deep sequencing data

miRExpress – Analyzing high-throughput sequencing data for profiling microRNA expression

miRanalyzer – A microRNA detection and analysis tool for next-generation sequencing experiments

CID-miRNA – Computational Identification of microRNA

miRCat – miRNA Categorizer
