Mutagenic responses of L5178Y mouse cells at the tk and hprt loci.


The expression of multiple recessive genes by aberrant mitotic lesions plays a major part in carcinogenesis. These lesions include intragenic mutations as well as chromosomal lesions. An in vitro model for studying carcinogenesis should respond to all these lesions. Mutagenesis studies that target hemizygous loci may not be useful in studying chromosomal… (More)
