PNGC is pleased to announce the release of the DASHR v2.0 database of human small non-coding RNAs (sncRNAs). DASHR v2.0 is freely available at https://lisanwanglab.org/DASHRv2. This is an extremely useful resource and reference for the community studying non-coding RNAs and their diverse roles in often tissue-specific cellular processes related to human diseases.

DASHR (Database of small human non-coding RNAs) v2.0 provides a complete catalog of annotation, expression, processing, conservation, tissue-specificity and other biological features for all human sncRNA genes, full sncRNA transcripts and mature products derived from all major small RNA classes, including miRNAs, piRNAs, sc-, sn-, sno- RNAs, tRNAs, tRFs.

Some of the DASHR v2.0 highlights include:

1) Integration of the largest collection of >180 tissues and cell types from ENCODE and GEO/SRA across multiple RNA-seq protocols for both GRCh38/hg38 and GRCh37/hg19;

2) The first database to profile both known sncRNA loci and novel, previously un-annotated sncRNA loci identified by genome-wide unsupervised segmentation;

3) Integration of >3,200,000 annotations for non-small RNA genes and other genomic features (e.g., long-noncoding RNAs, promoters);

4) Introduction of an enhanced user interface, interactive experiment-by-locus table views for easy sorting and filtering of small RNA loci data;

5) Access to genome wide expression tracks and called small RNA peaks freely downloadable and viewable in the UCSC Genome Browser.

DASHR 2.0 has been published in Bioinformatics.
