Abstract |
Background: The small cell lung cancer (SCLC) is an epithelial tumour with
the morphological and secretory characteristics of neuroendocrine cells
(neurone-specific enolase, N-CAM, neuropeptides). The establishment of a
SCLC cell line provides an in vitro model to analyze the neuroendocrine
secretion of these malignant cells.
Methods: Bombesin, delta sleep inducing factor (DSIP) and arginine
vasopressin (AVP) were studied by immunohistochemistry and by in situ
hybridization. NADPH diaphorase activity was detected using an
histochemical technique.
Results: All the cells contained bombesin, DSIP, AVP and displayed a NADPH
diaphorase activity with reflects a nitric oxide (NO) synthase activity.
Conclusions: These data present the characteristics of a new SCLC cell
line (CPN) and show the complexity of its neuroendocrine secretion; for
example, the presence of DSIP and NO synthase activity which have not yet
been demonstrated in other SCLC cell lines.
