MIR191 is a miRNA that has been found to have concentrations in patients with MHT, and it can provide additional information to improve indications for the need for an initial CCT scan [PMC7430915]. In a study, 36 miRNA orthologs were found to be mutually abundant between tumor types, and among them, MIR191 was one of the most notably expressed miRNA orthologs [PMC9210832]. The study used a circular heatmap in Figure-1 to present the expression levels of these miRNA orthologs [PMC9210832]. Additionally, four MEPNA for MIR191 were prepared with varying gap sizes (1-4 consecutive unmodified nucleotide units), with Amir-0 being an unmodified AO [PMC4005664]. These findings suggest that MIR191 is an important miRNA in the context of tumor types and can potentially be used as a biomarker for diagnostic purposes. Further research is needed to fully understand the role of MIR191 in these contexts.

Annotation confidence High
Do you think this miRNA is real?
This miRNA sequence is predicted based on homology to a verified miRNA from mouse [1]. The expression of this miRNA was later confirmed in human HL-60 leukemia cells [2]. The mature sequence shown here represents the most commonly cloned form from large-scale cloning studies [4].
