Using a xenotransplantation system in which immortalized nontumorigenic human bronchial epithelial cells (BEAS-2B cells) are grown in deepithelialized rat tracheas that are subcutaneously transplanted into athymic nude mice, we exposed BEAS-2B cells either to cigarette smoke condensate or to the tobacco-specific N-nitrosamine 4-(methylnitrosamine)-1-(3-pyridyl)-1- butanone. After 6 mo the carci...
We have previously demonstrated that diphenylarsinic acid (DPAA) promotes liver carcinogenesis in rats in a medium-term liver carcinogenicity bioassay. However, the effects of DPAA on other organs have not been determined. In the present study, the effects of DPAA on carcinogenesis were investigated using a rat multiorgan carcinogenicity bioassay. A total of 60 six-week-old male F344 rats were ...
The potential enhancing effects of the regeneration response of the urothelium following ulcération of the bladder mucosa on A/-butyl-/V-(4-hydroxybutyl)nitrosamine Carcinogenesis were examined in male Fischer rats. The carcinogen was adminis tered in the drinking water at a concentration of 0.05% for 2 weeks. Ulcérationwas performed by a freezing technique 24 hr before the administration or ...
