Abstract

mRNA is thought to predominantly reside in the cytoplasm, where it is translated and eventually degraded. Although nuclear retention of mRNA has a regulatory potential, it is considered extremely rare in mammals. Here, to explore the extent of mRNA retention in metabolic tissues, we combine deep sequencing of nuclear and cytoplasmic RNA fractions with single-molecule transcript imaging in mouse beta cells, liver, and gut. We identify a wide range of protein-coding genes for which the levels of spliced polyadenylated mRNA are higher in the nucleus than in the cytoplasm. These include genes such as the transcription factor ChREBP, Nlrp6, Glucokinase, and Glucagon receptor. We demonstrate that nuclear retention of mRNA can efficiently buffer cytoplasmic transcript levels from noise that emanates from transcriptional bursts. Our study challenges the view that transcripts predominantly reside in the cytoplasm and reveals a role of the nucleus in dampening gene expression noise.

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

  • Cytoplasmic RNA is enriched among genes more abundant in cells.

    “cytoplasmic RNA (defined by Bahar Halpern et al., 2015) was clearly enriched among genes found to be more abundant in cells (NES = −2.03, padj = 3.6e-05)”

    From Single-Nucleus RNA-Seq Is Not Suitable for Detection of Microglial Activation Genes in Humans (2020) · cites this paper as Bahar Halpern et al., 2015

  • Recent progress in epigenome analysis has included assays for single-cell ChIP-seq (Drop-ChIP), single-cell ATAC-seq, single-cell Hi-C, and single-cell DNA methylation.

    “Although most high-throughput single-cell profiling studies to date have focused on RNA and protein, recent progress in epigenome analysis185 has included assays for single-cell ChIP-seq (Drop-ChIP26), single-cell ATAC-seq27,28, single-cell Hi-C29 (a genome-wide derivative of the chromosome conformation capture (3C) technique), and single-cell DNA methylation22–25.”

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.
