Nicotine‐evoked disassembly of cortical actin filaments in adrenal chromaffin cells
Open accessAbstract
Using rhodamine‐phalloidin staining it was found that actin filaments are concentrated in the cortex of resting chromaffin cells. Cortical actin filaments were disassembled 15 s after stimulation by nicotine and had reassembled 30 s later. Actin filament disassembly following nicotinic stimulation was also detected using the DNase I inhibition assay. Disassembly was independent of external calcium, insensitive to trifluoperazine and was not elicited by high K+, muscarinic agonists or phorbol ester. Disassembly of cortical actin filaments may allow access of secretory granules to exocytotic sites and act in conjunction with a rise in intracellular free calcium to bring about the full secretory response due to nicotinic agonists.

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.
