title: A specific alpha-fetoprotein gene binding protein in alpha-fetoprotein producing rat hepatomas.
abstract: A specific alpha-fetoprotein (AFP) gene binding nuclear protein (Mol. Wt. 149,000) was determined in Morris hepatoma 7777 cells by the protein blotting technique. This protein is not present in normal adult rat liver and non-AFP producing Morris hepatoma 5123tc. Neoplasia induced in rats fed the hepatocarcinogen 3'-methyl-4-dimethylaminoazobenzine enhanced AFP gene activity and re-expressed specific AFP gene binding nuclear protein. The precise role of this protein in AFP gene regulation remains to be determined.
