How many peer-reviewed studies exist on microRNA and cancer?

As of 2025, more than 80,000 peer-reviewed studies have been published examining the relationship between specific microRNAs and cancer. This body of evidence spans more than 25 years of research since the discovery of miRNA in 1993. The three biomarkers used by OncuraKit — miR-21-5p, miR-375-3p, and miR-141-3p — have each individually been featured in more than 700 studies, collectively representing data from more than 70,000 patient and control samples. This is not an emerging or experimental technology. The underlying miRNA science is among the most studied in all of modern biomedical research, forming the foundation for the 2024 Nobel Prize in Physiology or Medicine.
