Relevance of In Vivo Models in Melanoma Skin Cancer

A discussion of possible wavelength dependence of induction of cutaneous malignant melanoma (CMM) is provided. Strengths and weaknesses of various experimental approaches to better understanding of the prevalence of CMM in different human populations including latitude effects are compared. Further the advantages and limitations of the use of the laboratory opossum (Monodelphis domestic), transgenic mice containing SV40 ongogene sequences under tyrosinase promoter control, and a backcross hybrid fish of the genus Xenophorus are contrasted.
