Welcome to the miRNA catalog.

miRNAs are small, non-coding RNAs that play a role in regulating gene expression. The data here contains miRNA in situ expression in xenopus embryos. The data and images is supplied courtesy of Grant Wheeler and Mike Gilchrist. The miRNAs have been correlated with miRBase miRNAs to provide more information. Click the miRNA links to view more information about the miRNA, including in situ images.
