Abstract

Averaged estimates of RNA polymerase II (RNAPII) elongation rates in mammalian cells have been shown to range between 1.3 and 4.3 kb min(-1). In this work, nascent RNAs from an integrated human immunodeficiency virus type 1-derived vector were detectable at the single living cell level by fluorescent RNA tagging. At steady state, a constant number of RNAs was measured corresponding to a minimal density of polymerases with negligible fluctuations over time. Recovery of fluorescence after photobleaching was complete within seconds, indicating a high rate of RNA biogenesis. The calculated transcription rate above 50 kb min(-1) points towards a wide dynamic range of RNAPII velocities in living cells.

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

  • Maiuri et al reported an extremely high RNA Pol II speed (about 80 kb/min) on an HIV-based vector integrated in one copy, whereas when integrated in 35 copies, RNA Pol II velocity was estimated at 1.6 kb/min.

    “Along the same line, Maiuri et al (2011) even reported an extremely high RNA Pol II speed (about 80 kb/min) on an HIV‐based vector integrated in one copy, whereas when integrated in 35 copies, RNA Pol II velocity was estimated at 1.6 kb/min, similar to earlier estimates from multicopy HIV‐derived vector insertions (Boireau et al, 2007).”

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.
