Abstract

Galectin-3, a β-galactoside-binding protein, is highly expressed in thyroid papillary carcinomas, while functional relevance of galectin-3 overexpression to the malignant phenotype remains elusive. In the present study we transfected galectin-3 antisense cDNA into the human thyroid papillary carcinoma cell line NPA which expresses an innately high level of galectin-3, and examined the effect of antisense inhibition of galectin-3 expression on the transformed phenotype. There was no difference in anchorage-dependent growth between the antisense clones and either the control or parental clones. In contrast, anchorage-independent growth and saturation density of the antisense clones were significantly suppressed compared to those of either the control or parental clones. These results demonstrate that overexpression of galectin-3 in thyroid papillary carcinoma cells is necessary for the maintenance of transformed phenotype, and suggest galectin-3 as a potential target for therapeutic interventions in the future.
