Utilization ofglutathione S-transferase Mu 1- andTheta 1-null mice as animal models for absorption, distribution, metabolism, excretion and toxicity studies

Glutathione S-transferases (GSTs) are Phase II drug-metabolizing enzymes that catalyze the conjugation of electrophilic compounds to glutathione. This reaction generally detoxifies reactive metabolites of xenobiotics, such as drugs and environmental chemicals, and therefore, GSTs are considered toxicologically important enzymes. Human GST genes display genetic polymorphisms, and the impact of null genotypes of GST Mu 1 (GSTM1) and GST Theta 1...
