Abstract

To develop an efficient animal model for colitis‐related carcinogenesis, male Crj: CD‐1 (ICR) mice were given a single intraperitoneal administration (10 mg/kg body weight) of a genotoxic colonic carcinogen, azoxymethane (AOM), and a 1‐week oral exposure (2% in drinking water) to a non‐genotoxic carcinogen, dextran sodium sulfate (DSS), under various protocols. At week 20, colonic neoplasms (adenocarcinomas, 100% incidence with 5.60±2.42 multiplicity; and adenomas, 38% incidence with 0.20±0.40 multiplicity) with dysplastic lesions developed in mice treated with AOM followed by DSS. Protocols in which AOM was given during or after DSS administration induced a few tubular adenomas or no tumors in the colon. Immunohistochemical investigation of such dysplasias and neoplasms revealed that all lesions were positive for β‐catenin, cyclooxygenase‐2 and inducible nitric oxide synthase, but did not show p53 immunoreactivity. The results indicate that 1‐week administration of 2% DSS after initiation with a low dose of AOM exerts a powerful tumor‐promoting activity in colon carcinogenesis in male ICR mice, and may provide a novel mouse model for investigating colitis‐related colon carcinogenesis and for identifying xenobiotics with modifying effects.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
