MicroRNAs (miRNAs) are endogenous, small non-coding RNAs that can regulate the expression of mRNAs post transcriptionally either via translational repression or mRNA degradation. Dysregulation of miRNA expression is observed in various diseases and altered physiological states. Mature miRNAs are single-stranded and approxi­mately 18-22 nucleotides long and can be extremely challenging to visualize in situ.

The new miRNAscope™ assay can:

  • Detect miRNAs implicated in cancer and distinguish between multiple members from the same family
    • Since miRNAs can efficiently regulate the expression of tumor suppressors as well as oncogenes, sever­al miRNAs have been implicated in cancer initiation and progression.

  • Provide functional information by identifying cell-type specific miRNAs in the brain 
    • miRNAs regulate gene expression in developing neuronal cells and are also implicated in pathogenesis of many neurological disorders, neuroinflammation and immune regulation.

  • Detect miRNAs significant in development and tissue homeostasis
    • miRNAs expressed in the developing tissues can support development, cellular differentiation, maturation, and survival.​
  • Detect miRNAs vital in immune cell regulation
    • miRNAs act as negative or positive feedback regulators of immune cell activation pathways within the cells.​

The miRNAscope assay is also compatible with the in situ hybridization - immunohistochemistry (ISH-IHC) workflow which allows visualization of RNA and pro­tein targets simultaneously. Co-detection of miRNA and protein targets can assist in expanding our un­derstanding of cell-specific expression of patho­logically relevant miRNAs.
