Cytochromes P450 are Expressed in Proliferating Cells in Barrett's Metaplasia

open access: yesNeoplasia: An International Journal for Oncology Research, 1999
The expression of cytochromes P450 (CYP) in Barrett's esophagus and esophageal squamous mucosa was investigated. Esophagectomy specimens from 23 patients were examined for CYP expression of CYP1A2, CYP3A4, CYP2C9/10, and CYP2E1 by immunohistochemical ...
