microRNAome; microRNAomics

MicroRNAs (miRNAs) are a class of small non-coding RNAs, which are negative regulators of gene expression.


- uterine leiomyoma (22446413)

  • Many genes in human uterine leiomyoma (ULM) are aberrantly expressed and in some cases this can be due to dysregulation of miRNAs.
  • More than 50 miRNAs are differentially expressed.
  • The top five significantly de-regulated miRNAs in ULMs are miR-363, miR-490, miR-137, miR-217 and miR-4792.
  • Some authors also observed "isomiRs" with higher copy number than referenced mature miRNA specific for the leiomyoma libraries, which have a potential role in tumorigenesis.
