Immunohistochemical detection of galectin-3 in canine gastric carcinomas.
Galectin-3 was detected immunohistochemically in nine canine gastric carcinomas. In normal gastric tissue adjacent to the neoplasms, the gastric epithelial cells showed faint immunolabelling for galectin-3, but in all the tumours the neoplastic cells showed moderate to strong immunolabelling. Galectin-3 was localized in the cytoplasm of the normal mucosal cells, whereas it was found in both the cytoplasm and the nucleus of the neoplastic cells. Positive cells typically exhibited dark brown coloration of the nucleus or cytoplasm, without background labelling. The results suggest that galactin-3 has a pathophysiological role in canine gastric carcinoma.
