## Abstract To investigate the presence of γ‐glutamyl transpeptidase (γGT) in brain cells, cultures enriched for astroglial cells, neurons, oligodendroglial cells, and microglial cells were studied. Astroglial cultures contained a specific γGT activity of 2.3 ± 0.9 nmol/min/mg protein. A similar sp
γ-Glutamyl transpeptidase is normally not present in adult rat hepatocytes, but its expression is induced by a range of xenobiotics, including carcinogens and chemopreventive agents. Synthesis of the enzyme is mediated by at least six mRNAs transcribed from tandemly arranged promoters on a single ge
