    Abstract

    Murine beta-galactoside-binding protein has been shown to be a cell growth regulatory molecule and a cytostatic factor. We analysed the beta-galactoside-binding protein gene expression in a thyroid cell system including two normal cell lines (FRTL-5 and PC Cl 3) and the same cells transfected by several oncogenes that induce different degrees of malignancy and differentiation. We show that beta-galactoside-binding protein mRNA levels correlate with the expression of the malignant phenotype. Run-on experiments suggest that a transcriptional effect accounts at least in part for such a difference. We also show that the beta-galactoside-binding protein gene expression is increased in most human papillary thyroid carcinomas compared with normal thyroid.
