Influence of Sendai virus on carcinogenesis in strain A mice.

Abstract

An alkylating derivative of a hydrocarbon, 10-chloromethyl-9-chloroanthracene, gave rise to reduced numbers of chemically induced pulmonary adenomas in strain A mice enzootically infected with Sendai virus, while in the case of 7,12-dimethylbenz(a)anthracene, the opposite relationship was observed. Therefore, the presence or absence of viral infection was demonstrated to have a strong influence on carcinogenic susceptibility.
