title: STK-1 receptor gene is expressed in various human non-hematopoietic tumor cell lines--RT-PCR directed analysis of STK-1 mRNA expression. Preliminary report.
abstract: The aim of this study was to evaluate the presence of the mRNA for the hematopoietic STK-1 receptor in various human tumor cell lines using RT-PCR directed analysis of gene expression. We have found STK-1R mRNA to be expressed in non-hematopoietic malignant cells of ectodermal, endodermal and mesodermal origin confirms a hypothesis that STK-1R is similar to other receptors with intrinsic tyrosine kinase activity, is not for specific hematopoiesis and is also expressed in non-hematopoietic cells. The fact that STK-1R is detectable in different tumor cell lines should also inspire further studies to evaluate its role in the transformation and growth of malignant cells.
