Global profiling and annotation of templated isomiRs dynamics across Caenorhabditis elegans development

open access: yesRNA Biology, 2022
microRNAs (miRNAs) are small non-coding RNAs that regulate gene expression through translational repression and mRNA destabilization. During canonical miRNA biogenesis, several miRNA isoforms, or isomiRs, are produced from a single precursor miRNA ...

Plant IsomiR Atlas: Large Scale Detection, Profiling, and Target Repertoire of IsomiRs in Plants

open access: yesFrontiers in Plant Science, 2019
microRNAs (miRNAs) play an important role as key regulators controlling the post-transcriptional events in plants across development, abiotic and biotic stress, tissue polarity and also in defining the evolutionary basis of the origin of the post ...

Evaluation of high-throughput isomiR identification tools: illuminating the early isomiRome of Tribolium castaneum

open access: yesBMC Bioinformatics, 2017
Background MicroRNAs carry out post-transcriptional gene regulation in animals by binding to the 3' untranslated regions of mRNAs, causing their degradation or translational repression. MicroRNAs influence many biological functions, and dysregulation can

Flexible pri-miRNA structures enable tunable production of 5’ isomiRs

open access: yesRNA Biology, 2022
The Drosha cleavage of a pri-miRNA defines mature microRNA sequence. Drosha cleavage at alternative positions generates 5’ isoforms (isomiRs) which have distinctive functions. To understand how pri-miRNA structures influence Drosha cleavage, we performed

Tumor classification and biomarker discovery based on the 5’isomiR expression level

open access: yesBMC Cancer, 2019
Background The miRNA isoforms (isomiRs) have been suggested to regulate the same pathways as the canonical miRNA and play an important biological role in miRNA-mediated gene regulation.

Seminal Plasma Exosomal miRNA Profiling Reveals hsa‐miR‐7‐5p as a Key Regulator of Sperm Motility in Asthenozoospermia

open access: yesAndrology, EarlyView.
ABSTRACT Background Asthenozoospermia is a significant contributing factor to male infertility. Accumulating evidence indicates that impaired sperm motility is closely linked to dysregulated microRNA expression during spermatogenesis. Seminal plasma exosomes are enriched with diverse microRNAs, which play pivotal roles in modulating sperm motility, the

Concordant and discordant regulation of target genes by miR-31 and its isoforms. [PDF]

open access: yesPLoS ONE, 2013
It has been shown that imprecise cleavage of a primary or precursor RNA by Drosha or Dicer, respectively, may yield a group of microRNA (miRNA) variants designated as "isomiR".

Transfer RNA-Derived Fragments and isomiRs Are Novel Components of Chronic TBI-Induced Neuropathology

open access: yesBiomedicines, 2022
Neuroinflammation is a secondary injury mechanism that evolves in the brain for months after traumatic brain injury (TBI). We hypothesized that an altered small non-coding RNA (sncRNA) signature plays a key role in modulating post-TBI secondary injury ...

MicroRNA‐Driven Regulation of β‐Cell Function in Type 2 Diabetes: Molecular Mechanisms, Network Insights, and Translational Perspectives

open access: yesActa Physiologica, Volume 242, Issue 9, September 2026.
ABSTRACT MicroRNAs (miRNAs) have emerged as central regulators of pancreatic islet biology, influencing β‐cell development, proliferation, and function. In type 2 diabetes (T2D), both adaptive and maladaptive miRNA responses shape β‐cell compensation and progressive secretory dysfunction.

Rewired functional regulatory networks among miRNA isoforms (isomiRs) from let-7 and miR-10 gene families in cancer

open access: yesComputational and Structural Biotechnology Journal, 2020
Classical microRNA (miRNA) has been so far believed as a single sequence, but it indeed contains multiple miRNA isoforms (isomiR) with various sequences and expression patterns.
