Abstract:
:Melanoma formation in Xiphophorus hybrids is mediated by a growth factor receptor tyrosine kinase oncogene encoded by the Tu locus. In the wild-type parental fish no tumors occur due to the activity of a locus that regulates the activity of the melanoma oncogene. Molecular identification of this regulatory locus (R) requires a precise physical map of the chromosomal region. Therefore we studied esterase isozymes in Xiphophorus, two of which have been previously reported to be linked to locus R. We confirm that ES1 is a distant marker for R (approx. 30cM), and contrary to earlier studies, we show that this isozyme is present in all species of the genus and at similar activity levels in all organs tested. ES4, which has also been reported to be linked to R, was found to be a misclassification of liver ES1. In an attempt to identify markers that bridge the large distance between ES1 and R, we have generated DNA probes which are highly polymorphic. They will be useful in finding landmarks on a physical map of the R-containing chromosomal region.
