Abstract

Neuroendocrine hamster lung tumors, induced by exposure to 60% hyperoxia and subcutaneous administration of the tobacco-specific nitrosamine 4-(methylnitrosamino)-l-(3-pyridyl)-l-butanone (NNK) for 12 weeks, were placed in cell culture. By subsequent selective transfer of epithelial cells and maintenance in an atmosphere of 8% CO2, cell lines with characteristics of neuroendocrine cells were established. The neuroendocrine markers expressed by these cell lines included electron dense neuroendocrine secretion granules as well as secretion of calcitonin and mammalian bombesin. In keeping with data previously reported for a human neuroendocrine lung tumor cell line, nicotine, acetylcholine, and mammalian bombesin (MB) acted as strong growth factors in these neuroendocrine hamster tumor lines. The mitogenic effect of nicotine and acetylcholine was abolished by nicotinic receptor inhibition while the effects of mammalian bombesin were inhibited by an antagonist of MB receptors. Our data suggest that a receptor-mediated mitogenic effect of nicotine on neuroendocrine lung cells may be instrumental in the induction of smoking-associated small cell lung cancer.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Different groups observed that respiration hyperoxia can act as a promoting stimulus to induce lung tumorigenesis of neuroendocrine tumors.

    “Conversely, different groups have observed that respiration hyperoxia can act as a promoting stimulus to induce lung tumorigenesis of neuroendocrine tumors.”

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.
