Cytogenetic analysis of oral and cutaneous squamous cell carcinomas in the rat.


Chromosomes of induced carcinomas in the oral mucosa and epidermis of rats were studied in vitro. The tumours were induced by repeated applications of one of two carcinogens: the fat-soluble 7,12-dimethylbenz (a) anthracene (DMBA) or the water-soluble 4-nitrochinoline N-oxide (4NQO). Non-random chromosomal patterns, different for each carcinogen, were… (More)
