Cyclic AMP-induced expression of the mouse lactate dehydrogenase-A promoter-cat fusion gene in Chinese hamster ovary wild-type cells, but not in cAMP-dependent protein kinase mutant cells.

The promoter region of mouse lactate dehydrogenase-A gene was fused with the chloramphenicol acetyltransferase gene of Escherichia coli, and the expression of this fusion gene was induced by cyclic AMP in Chinese hamster ovary wild-type cells, but not in mutants affecting the regulatory or catalytic subunit of cAMP-dependent protein kinase.
