Experiments

The RNA-Seq and microarray gene- and miRNA-expression experiments included in RegenDbase are pre-analyzed.

To nominate an experiment for inclusion in RegenDbase, please contact us.

RNA-Seq

Microarray

Genes

RegenDbase integrates Ensembl genes and miRBase miRNAs for humans, mice, nematodes, and zebrafish, but we create our own gene vocabulary for axolotls....

Gene Annotations

GO annotations are integrated from Ensembl.

Pathway annotations are integrated from NCBI BioSystems, and include annotations from BioCyc, KEGG, Pathway Interaction Database, Reactome, and WikiPathways.

miRNA Target Predictions

RegenDbase creates new miRNA target predictions for certain organisms when we integrate new releases of Ensembl and miRBase.

miRNA target predictions are created by RegenDbase using the default parameters of the miRanda software.

Accession Identifiers

Wherever possible, data integrated into RegenDbase are identified by the unique accession identifiers assigned by their original source. Where such IDs are not available, however, RegenDbase assigns its own.

RegenDbase accession IDs are composed of a prefix based on the data type, followed by a series of digits (e.g., "REGENG:627"):

Accession Prefix Data Type
REGENE: Experiments
REGENG: Genes that are not mappable to Ensembl (e.g., axolotl genes)
REGENR: References that not represented in PubMed
REGENS: Experiment samples
