title: Cloning and expression of cDNA for two endogenous UV-2237 fibrosarcoma lectin genes.
abstract: cDNA libraries from the murine UV-2237-IP3 fibrosarcoma cell line were prepared in the expression vector lambda gt11. Using specific antibodies, cDNA clones coding for the 14.5-kDa and the 34.0-kDa endogenous galactoside-specific lectins were isolated. In vitro translation and immunoprecipitation of mRNAs hybrid-selected by the cloned sequences from whole cell RNA provided confirmation for the clones. RNA and DNA blot analyses revealed that the two lectin proteins represent products of two different genes. We found differential levels of the specific mRNAs when low- and high-metastatic counterparts of the UV-2237 tumor system were compared, and these genes were not expressed in detectable amounts in normal mouse liver.
