title: Development of glutathione S-transferase placental form (GST-P) stained foci during hamster buccal pouch mucosa carcinogenesis.
abstract: The expression of the placental form of glutathione S-transferase (GST-P) using anti-rat liver GST-P antibody was investigated in hamster buccal pouch mucosa (HBPM) treated with 0.5% dimethylbenz[a]anthracene (DMBA) biweekly for 12 weeks. This preliminary study showed that the anti-rat liver GST-P antibody is applicable to the HBPM model and that DMBA treatment induced GST-P positive foci. These foci are randomly distributed and frequently involved the hyperplastic and dysplastic segments of the epithelium, as well as squamous cell carcinoma. Further study is needed to explore the kinetics of these GST-P positive foci.
