Analysis of 13 cell types reveals evidence for the expression of numerous novel primate- and tissue-specific microRNAs
Open accessAbstract
Significance: MicroRNAs (miRNAs) are small ∼22-nt RNAs that are important regulators of posttranscriptional gene expression. Since their initial discovery, they have been shown to be involved in many cellular processes, and their misexpression is associated with disease etiology. Currently, nearly 2,800 human miRNAs are annotated in public repositories. A key question in miRNA research is how many miRNAs are harbored by the human genome. To answer this question, we examined 1,323 short RNA sequence samples and identified 3,707 novel miRNAs, many of which are human-specific and tissue-specific. Our findings suggest that the human genome expresses a greater number of miRNAs than has previously been appreciated and that many more miRNA molecules may play key roles in disease etiology.

Written from the paper’s full text.
TL;DR
Analyzing 1,323 short RNA-seq samples from 13 human cell types, this study identifies 3,707 novel mature miRNAs from 3,494 precursors at FDR ≤ 0.05, many of which are tissue-specific and primate-specific. The authors argue that public repositories substantially underrepresent the human miRNA repertoire.
Key findings
- From >23 billion sequenced reads, ~8.2 billion mapped unambiguously; 3,707 novel mature miRNAs were identified, and 91.5% (3,392 of 3,707) were discovered independently in at least 10 samples.
- Ago CLIP-seq supported 1,657 of 3,707 novel miRNAs (44.7%), compared with 1,517 of 2,772 miRBase release 20 miRNAs (54.7%).
- Novel miRNAs showed strong tissue dependence: low intertissue Jaccard similarity, PCA clustering by tissue, and stem-loop RT-PCR confirmation of 20 novel miRNAs in 12 cell lines representing 5 tissues.
- Conservation analysis found 56.7% of novel miRNAs human-specific and 94.4% primate lineage-specific; 2,140 (58.1%) precursor/mature combinations were human-specific, 476 (12.8%) shared across Hominidae, 109 (2.9%) present in mouse, and none in Drosophila or worm.
Methods
- Analyzed 1,323 short RNA-seq samples (100 in-house, 1,223 public) from 13 human cell types; reads were mapped to hg19 with SHRiMP2, processed per sample with miRDeep2, and filtered to mature miRNAs with FDR ≤ 0.05 after removing known miRNAs, mirtrons, tRNAs, snRNAs, and rRNAs.
- Used 43 Ago CLIP-seq samples (10 in-house, 33 public) to assess Argonaute loading, requiring complete coincidence with a CLIP-seq site, observation in at least one sample, and support by five or more reads.
- Validated selected novel miRNAs by stem-loop RT-PCR in 12 cell lines, assessed DICER dependence in MCF7 knockdown data, performed GLSEARCH conservation analysis, seed-based clustering, and RNA22 target prediction.
Limitations
- The paper states that the 43 Ago CLIP-seq samples represent only 3 of the 13 tissue types used for discovery, so not all novel or miRBase miRNAs are expected to be observed; lower Ago support for novel miRNAs is expected given their higher tissue specificity.
- The paper states that the study focused only on canonical Dicer-dependent miRNAs, while bona fide miRNAs can arise through other mechanisms, suggesting an even larger miRNA-ome.
- The paper states that RNA22 target predictions require additional experimental validation; only 20 novel miRNAs were experimentally tested by stem-loop RT-PCR.

MiRNAs loaded onto the Argonaute complex are capable of interacting with target RNAs.
“MiRNAs exert their function through their association with the Argonaute complex, and, thus, those miRNAs loaded onto Ago are expected to be capable of interacting with target RNAs.”

In the citing paper
“The PhyloP conservation data (Fig. 3B) show that, beyond the most ideal microRNAs identified in miRGeneDB, there is a lack of genetic conservation, with overlap in a large segment of miRBase microRNAs and the novel microRNAs reported here and in a prior large study (Londin et al. 2015).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-11-06, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-11-06 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
