One of the major features of {beta}-glucuronidase (GUS) expression in inbred strains of the house mouse, Mus musculus, is the responsiveness of this enzyme to androgen stimulation in tubule cells of the kidney. Both GUS-specific and nonspecific mutations have been described which define genes that serve to control this response. During examination of the expression of GUS in the interbreeding subspecies, Mus hortulanus, a new GUS haplotype was uncovered that is characterized, in part, by a lack of GUS response to androgen stimulation in an apparently responsive kidney. Blot hybridization analyses of kidney RNA with a radiolabeled murine GUS cDNA shows this lack of response to be reflected in GUS mRNA levels. The difference in heat stability of GUS activity between M. hortulanus and a responsive inbred strain, ICR/Ha, was utilized to assess the contribution of each parent to kidney levels of GUS in androgen-treated and -untreated F(1) progeny of these strains. The results, together with preliminary genetic studies, suggest that the element controlling this responsiveness (or the lack thereof) is cis-active and tightly linked to the GUS structural gene on chromosome 5. It is not known whether this element is identical to another GUS-specific, cis-active element, Gus-r, which also controls the androgen response of GUS in mouse kidney.
