  • At low concentrations, cytochalasins primarily cap the barbed ends of actin filaments.

    “at low concentrations, their primary effect in cells is to cap the barbed ends of actin filaments (3).”
  • Low concentrations of AAIs (0.01-1 μM) are similar to those shown previously to alter actin filament organization in cultured cells, prevent lamellipodial ruffling in fibroblasts, inhibit motility and retrograde flow in neuronal growth cones, and arrest dendritic spine motility in hippocampal neurons.

    “The concentrations of latrunculin A and cytochalasins used here (0.01–1 μM) are similar to those that have been shown previously to alter actin filament organization in cultured cells, prevent lamellipodial ruffling in fibroblasts, inhibit motility and retrograde flow in neuronal growth cones, and arrest dendritic spine motility in hippocampal neurons (3, 4, 7, 10).”

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.
