Abstract

BACKGROUND: Degradation rate is a fundamental aspect of mRNA metabolism, and the factors governing it remain poorly characterized. Understanding the genetic and biochemical determinants of mRNA half-life would enable more precise identification of variants that perturb gene expression through post-transcriptional gene regulatory mechanisms. RESULTS: We establish a compendium of 39 human and 27 mouse transcriptome-wide mRNA decay rate datasets. A meta-analysis of these data identified a prevalence of technical noise and measurement bias, induced partially by the underlying experimental strategy. Correcting for these biases allowed us to derive more precise, consensus measurements of half-life which exhibit enhanced consistency between species. We trained substantially improved statistical models based upon genetic and biochemical features to better predict half-life and characterize the factors molding it. Our state-of-the-art model, Saluki, is a hybrid convolutional and recurrent deep neural network which relies only upon an mRNA sequence annotated with coding frame and splice sites to predict half-life (r=0.77). The key novel principle learned by Saluki is that the spatial positioning of splice sites, codons, and RNA-binding motifs within an mRNA is strongly associated with mRNA half-life. Saluki predicts the impact of RNA sequences and genetic mutations therein on mRNA stability, in agreement with functional measurements derived from massively parallel reporter assays. CONCLUSIONS: Our work produces a more robust ground truth for transcriptome-wide mRNA half-lives in mammalian cells. Using these revised measurements, we trained Saluki, a model that is over 50% more accurate in predicting half-life from sequence than existing models. Saluki succinctly captures many of the known determinants of mRNA half-life and can be rapidly deployed to predict the functional consequences of arbitrary mutations in the transcriptome.

  • Sequence-based models of post-transcriptional regulation rely on genome annotations and transformed measurements extracted from RNA-seq to isolate each regulatory mechanism.

    “Similarly, sequence-based models of post-transcriptional regulation rely on genome annotations and transformed measurements extracted from RNA-seq to isolate each regulatory mechanism (for example, percent spliced-in for splicing)14–23.”

    From Predicting RNA-seq coverage from DNA sequence as a unifying model of gene regulation (2025) · cites this paper as [23]

    The Methods sections on gene annotations, half-life data pre-processing, and Saluki training describe a sequence-based model that uses annotated mRNA structure and transformed half-life measurements to study RNA degradation. The paper does not establish that all those measurements were extracted from RNA-seq, and it models mRNA decay rather than the cited sentence’s splicing example (percent spliced-in). (LLM, conf=0.78)

  • The paper did not find sequence elements related to mRNA half-life in Borzoi's sequence attributions.

    “Furthermore, we did not find sequence elements related to mRNA half-life in Borzoi’s sequence attributions23,82.”

    From Predicting RNA-seq coverage from DNA sequence as a unifying model of gene regulation (2025) · cites this paper as [23]

    The Results section, ‘A deep learning-based genetic model of mRNA half-life,’ identifies sequence motifs associated with changes in half-life. It analyzes Saluki, however, and does not report a failure to find those elements in Borzoi’s sequence attributions; the citing authors’ ‘we did not find’ is not a finding of this source. (LLM, conf=0.85)

  • Prior work has demonstrated strong relationships between codon usage and mRNA half-life.

    “Prior work has demonstrated strong relationships between codon usage and mRNA half-life23,78.”
  • Borzoi performs better than a 3′ UTR-wide ensemble of APARENT2 and Saluki at longer distances (dAUPRC > 0.050 at 2,000 bp) and comparably closer to the PAS (dAUPRC = 0.025 at 50 bp).

    “Borzoi performs better at longer distances (dAUPRC > 0.050 at 2,000 bp) with a more comparable performance closer to the PAS (dAUPRC = 0.025 at 50 bp) (Fig. 6g).”

    From Predicting RNA-seq coverage from DNA sequence as a unifying model of gene regulation (2025) · cites this paper as [23]

    The Results section on 3′ UTR regulatory function reports Saluki’s performance against experimental data, and its Fig. 6 caption describes panels a–e. Our copy does not address a Borzoi comparison or the stated dAUPRC values at 2,000 bp and 50 bp (searched: Borzoi, APARENT2, dAUPRC, and PAS distance). (LLM, conf=0.78)

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.
