Immunohistochemical detection of Fhit expression. (A) Fhit expression in normal esophageal epithelium (×200) of Fhit +/+ mouse 23 at 10 wk post NMBA; the brown chromogen represents the Fhit protein. (B) Lack of Fhit expression in a squamous papilloma of the forestomach (×200) in Fhit +/− mouse 33 at 10 wk post NMBA; (C) Absence of Fhit expression in a squamous papilloma of the junction (×200) in Fhit +/+ mouse 25 at 10 wk post NMBA; (D) Lack of Fhit expression in an invasive squamous carcinoma of the forestomach (×100) in Fhit +/− mouse 31 at 10 wk post NMBA; (E) Lack of Fhit expression in a sebaceous tumor (×100) in Fhit +/− mouse 27 at 10 wk post NMBA; (F) Absence of Fhit protein in a sebaceous tumor (×100) in Fhit +/− mouse 21 at 10 wk post NMBA.
