Pulmonary Bombesin and Calcitonin in Hamsters during Exposure to Hyperoxia and Diethylnitrosamine

Abstract

Combined exposure of hamsters to 60% hyperoxia and the carcinogen diethylnitrosamine for 6 wk resulted in the development of lung tumors. This was associated with progressive loss of body weight as well as increases in the pulmonary-associated peptides, mammalian bombesin (MB) and immunoreactive calcitonin (iCT). After 3 wk of exposure, multiple bronchial epithelial hyperplastic foci were noted, along with increased lung levels of MB and iCT as well as increased serum levels of MB. At this time, immunocyto-chemistry revealed the presence of MB and iCT within hyperplastic pulmonary neuroendocrine (PNE) cells. In addition, the localization of MB to alveolar type II cells was noted, along with the presence of lamellar bodies and secretion granules in these cells on electron microscopy. After 6 wk of exposure, distinctive microscopic pulmonary tumorlets were seen. These tumorlets were associated with a marked increase in lung and serum MB, and to a lesser extent lung and serum iCT. At this time, MB and iCT were localized exclusively to these abnormal PNE cell sites. These results, which may have relevance in humans, suggest that endogenous peptides may be important components in the process of development of neuroendocrine cancer.

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.
