Sodium butyrate was used to enhance biosynthesis rates of recombinant human gamma-glutamyl transferase (GGT) expressed under the control of the SV40 or the cytomegalovirus immediate early promoter, respectively, in transfected V79 and CHO Chinese hamster cell lines. Maximal induction of GGT specific activity in butyrate-treated cells ranged from 3 to 5-fold and resulted from a strong increase in the GGT mRNA ratio. We also observed that maximal transcription level in V79 cells occurred within 12 hr of treatment, whilst the cell proliferation was transiently arrested. Despite its processing requirements, induced GGT exhibited unchanged catalytic and physico-chemical features relative to human serum or hepatoma enzyme, thus appearing as an excellent model for further studies on human GGT.
