title: Molecular cloning of rat mitochondrial glutamic oxaloacetic transaminase mRNA and regulation of its expression in regenerating liver.
abstract: cDNA clones for rat mitochondrial glutamic oxaloacetic transaminase (mGOT) have been isolated from a rat liver cDNA library. One of the clones, designated p501, contained a cDNA insert of 1.4 kilobase pairs in length and hybridized to a mRNA of 2.4 kilobases from rat liver. We measured mGOT mRNA content in a regenerating rat liver. In a regenerating rat liver, mGOT activity was increased and reached maximum (170% of control activity) at about 48 h following the operation. Using the cDNA of mGOT, it was revealed that the increase of mGOT in the regenerating rat liver depended on its mRNA content.
