Abstract

MicroRNAs (miRNAs) are evolutionarily conserved, 18- to 25-nucleotide, non–protein coding transcripts that posttranscriptionally regulate gene expression during development. miRNAs also occur in postmitotic cells, such as neurons in the mammalian central nervous system, but their function is less well characterized. We investigated the role of miRNAs in mammalian midbrain dopaminergic neurons (DNs). We identified a miRNA, miR-133b, that is specifically expressed in midbrain DNs and is deficient in midbrain tissue from patients with Parkinson's disease. miR-133b regulates the maturation and function of midbrain DNs within a negative feedback circuit that includes the paired-like homeodomain transcription factor Pitx3. We propose a role for this feedback circuit in the fine-tuning of dopaminergic behaviors such as locomotion.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • miR-133b is enriched in midbrain dopaminergic neurons and was found to be deficient in the parkinsonian midbrain.

    “miR-133b is enriched in midbrain dopaminergic neurons and was found to be deficient in the parkinsonian midbrain [101].”

    From RhoA Signaling in Neurodegenerative Diseases (2022) · cites this paper as [101]

  • miR-27a/b are expressed in SN of human midbrain.

    “miR-27a/b are expressed in SN of human midbrain (Additional file 2a) [34–36]”

    From miR-27a and miR-27b regulate autophagic clearance of damaged mitochondria by targeting PTEN-induced putative kinase 1 (PINK1) (2016) · cites this paper as [35]

    The expression-analysis passage (p. 2) describes human midbrain samples and a panel of miRNAs, but identifies miR-133b rather than miR-27a/b. Searches for miR-27a/b and substantia nigra expression found no passage in our copy establishing the claimed expression. (LLM, conf=0.75)

    Experimental — accuracy not yet measured
  • miR-27a/b are expressed in human midbrain.

    “Several previous studies showed that miR-27a/b are expressed in human midbrain [34–36].”

    From miR-27a and miR-27b regulate autophagic clearance of damaged mitochondria by targeting PTEN-induced putative kinase 1 (PINK1) (2016) · cites this paper as [35]

    The expression-analysis passage (p. 2) describes a panel of approximately 230 miRNAs tested in human midbrain, but does not identify miR-27a or miR-27b. Searches for “miR-27a miR-27b human midbrain” and “miR-27” found no passage in our copy establishing their expression there. (LLM, conf=0.73)

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.

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.
