MiR-128-3p – a gray eminence of the human central nervous system

Open access

Abstract

MicroRNA-128-3p (miR-128-3p) is a versatile molecule with multiple functions in the physiopathology of the human central nervous system. Perturbations of miR-128-3p, which is enriched in the brain, contribute to a plethora of neurodegenerative disorders, brain injuries, and malignancies, as this miRNA is a crucial regulator of gene expression in the brain, playing an essential role in the maintenance and function of cells stemming from neuronal lineage. However, the differential expression of miR-128-3p in pathologies underscores the importance of the balance between its high and low levels. Significantly, numerous reports pointed to miR-128-3p as one of the most depleted in glioblastoma, implying it is a critical player in the disease's pathogenesis and thus may serve as a therapeutic agent for this most aggressive form of brain tumor. In this review, we summarize the current knowledge of the diverse roles of miR-128-3p. We focus on its involvement in the neurogenesis and pathophysiology of malignant and neurodegenerative diseases. We also highlight the promising potential of miR-128-3p as an antitumor agent for the future therapy of human cancers, including glioblastoma, and as the linchpin of brain development and function, potentially leading to the development of new therapies for neurological conditions.

TL;DR

This review synthesizes the roles of miR-128-3p in the human central nervous system, emphasizing its brain enrichment and context-dependent deregulation in neurodegeneration, injury, and malignancies. It highlights glioblastoma as a key therapeutic target because miR-128-3p is depleted and its restoration targets polycomb repressive complexes and may enhance antitumor immunity.

Key findings

  • miR-128-3p is one of the most highly expressed microRNAs in the CNS; it is encoded by two genes, hsa-MIR128-1 (chromosome 2q21.3, within R3HDM1) and hsa-MIR128-2 (chromosome 3p22.3, within ARPP-21), and both loci yield identical mature miR-128-3p after DICER processing.
  • In non-malignant CNS pathologies, miR-128-3p is up-regulated in Alzheimer’s disease, multiple sclerosis, Parkinson’s disease, and acute ischemic stroke, but down-regulated in epilepsy and spinal cord injury/neuropathic pain (Table 1).
  • In CNS malignancies, miR-128-3p expression is inversely correlated with tumor grade: lowest in glioblastoma (grade 4), relatively high in oligodendrogliomas (grade 2 or 3), no significant differences in meningiomas or pituitary tumors, and suppressed in aggressive pituitary adenomas. Glioblastoma accounts for more than 80% of primary brain tumors and has a median survival of only 14–16 months.
  • Reintroducing miR-128-3p in glioblastoma stem-like cells targets PRC1/PRC2 components BMI1 and SUZ12, shifts cells from the mesenchymal toward the proneural subtype, reduces viability and neurosphere formation, decreases tumor burden and improves survival in mouse intracranial xenografts, and enhances radiosensitivity.

Methods

  • Design: narrative review summarizing current knowledge of miR-128-3p in CNS physiology and pathology, including neurogenesis, neurodegenerative disease, brain injury, and CNS malignancies.
  • Data/sample: published literature plus public datasets, including the Human microRNA Tissue Atlas accessed December 2023 for tissue and brain-region expression figures, The Cancer Genome Atlas glioblastoma dataset for a correlation signature of ∼1,700 genes, and CLIP-Seq data for non-coding RNA interaction networks.
  • Main analysis: synthesis of reported expression changes, target genes, molecular pathways, immune effects, and therapeutic strategies; tabular summaries of miR-128-3p deregulation in CNS disease and malignancy.

Limitations

  • Stated: miR-128-3p effects are context-dependent, and its therapeutic use carries potential off-target effects; further research is needed to unravel precise mechanisms in different CNS pathologies.
  • Stated: current microRNA modulation methods using oligonucleotides and gene therapies remain challenging for neurological conditions, and none have yet been approved for clinical use; EV-based delivery requires optimization and standardization of isolation, characterization, biodistribution, pharmacodynamics, and pharmacokinetics.
  • Evident from the text: as a review, it presents no new primary experimental data, and many cited findings derive from animal models, in vitro systems, or preclinical studies, limiting direct causal inference in humans.

Figure 3 The canonical pathway of miR-128 biogenesis The hsa-MIR128-1 gene resides within an intron of the R3HDM1 protein-coding gene on chromosome 2 (q21.3), whereas the hsa-MIR128-2 gene is located on chromosome 3 (p22.3) within an intron of the ARPP-21 protein-coding gene. These genomic loci undergo RNA Pol II/III transcription, yielding an extended primary transcript (pri-microRNA). Subsequently, the microRNA complex, composed of the endoribonuclease DROSHA and the RNA-binding protein DGCR8, cleaves these pri-microRNAs in the nucleus, generating precursor microRNAs (pre-microRNAs). The exportin-5 (XPO5)/Ran-guanosine triphosphate (Ran-GTP) complex recognizes the pre-microRNA, facilitating its translocation from the nucleus to the cytoplasm. Once in the cytoplasm, the DICER complex further processes the pre-microRNA, producing a short microRNA duplex. The duplex undergoes unwinding, with one strand becoming the mature microRNA and the other being degraded. It is important to note that the hsa-MIR128 gene produces two mature microRNA variants, miR-128-3p, and miR-128-5p, resulting from this processing pathway. Notably, both loci ultimately yield an identical mature miR-128-3p upon DICER processing.

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 2026-11-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-11-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Cited sources are checked with a language model’s help (gpt-6-sol).

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.
