Nature, Nurture, or Chance: Stochastic Gene Expression and Its Consequences

Open access
Raj, Arjun, van Oudenaarden, Alexander·2008·Cell

Abstract

Gene expression is a fundamentally stochastic process, with randomness in transcription and translation leading to cell-to-cell variations in mRNA and protein levels. This variation appears in organisms ranging from microbes to metazoans, and its characteristics depend both on the biophysical parameters governing gene expression and on gene network structure. Stochastic gene expression has important consequences for cellular function, being beneficial in some contexts and harmful in others. These situations include the stress response, metabolism, development, the cell cycle, circadian rhythms, and aging.

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

  • Intrinsic variability arises from random biochemical reactions of biological molecules over time.

    “Intrinsic variability arises from random biochemical reactions of biological molecules over time23.”
  • Allele-intrinsic variation is due to stochastic factors intrinsic to the molecular mechanisms that control gene expression.

    “The second is allele-intrinsic variation, namely stochastic factors intrinsic to the molecular mechanisms that control gene expression40–42.”
  • Allele-extrinsic variation is due to factors extrinsic to transcription, such as the presence of certain regulators or differences in stable chromatin state.

    “The third is allele-extrinsic variation, due to factors42,43 extrinsic to the process of transcription, such as the presence of certain regulators or differences in stable chromatin state.”
  • Transcript abundance is affected not only by allele-extrinsic factors, but also by allele-intrinsic stochasticity, resulting in its divergence across cells exposed to the same extrinsic triggers.

    “First, transcript abundance is affected not only by allele-extrinsic factors, but also by allele-intrinsic stochasticity, resulting in its divergence across cells exposed to the same extrinsic triggers42,43 (see above and Fig. 2).”

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.
