Abstract

The expression of rat Glutathione S-transferase P (GST-P) gene can be induced by many kinds of chemical inducers. We have studied the mechanisms of the expression ofGST-P gene induced by 3 kinds of chemical inducers using the induction of the gene expression by chemical inducers, transient transfection, reporter gene assays, electrophoretic mobility shift assays (EMSA) and Northern blot analysis. The results indicate that the effects and mechanisms of chemical inducers on the expression ofGST-P gene are different. The interaction of AP-1 or other corresponding transcription factors activated by phorbol ester (TPA) or glycidyl methatylate (GMA) and GPEI enhancer element induces the expression ofGST-P gene, while some unknown factors activated by H2O2 interact with GPEII enhancer element.
