Application of the alkane n-dodecane to the dorsal skin of 6-8 week old female SENCAR mice initiated with 10 nmol dimethylbenz[a]anthracene led to papilloma formation in the majority of treated animals. Compared to the potent phorbol diester 12-O-tetradecanoylphorbol-13-acetate (TPA), n-dodecane was
The induction of sustained epidermal hyperplasia in mouse skin has been shown to be a reliable predictor of tumor promoting activity for chemicals as diverse as phorbol esters, anthralins, n-dodecane and organic peroxides (DiGiovanni, 1992). The results contained herein demonstrate that API 81-07
Responses of various cells of the epidermis and dermis to topically applied agents have been implicated in the mechanism of multistage mouse tumorigenesis. These responses have been discussed almost entirely in the context of a single promoter treatment, although tumor expression is dependent on
Topical application of certain petroleum middle distillates (PMD) to mice produces skin tumors after long latency, and initiation/promotion protocols indicate that this effect is associated with their tumor promoting activity. Since induction of sustained, potentiated epidermal hyperplasia is
