| abstractText | The levels of expression and genomic organization of genes coding for the major urinary proteins (MUPs) were examined in several stocks of wild-derived mice. Levels of MUP mRNA in the liver varied considerably with M. musculus Brno and M. castaneus males having several-fold more MUP RNA than inbred C57BL/6 males, whereas M. hortulanus, M. caroli and M. cervicolor displayed levels much lower than C57BL/6. Analysis of RNA with MUP cDNAs specific to two different subfamilies of MUP genes revealed that M. caroli and M. cervicolor primarily expressed a MUP mRNA that was less abundant in C57BL/6, suggesting differential expression of subfamilies of genes within the MUP multigene complex. Although inbred males usually have five-fold more MUP mRNA than inbred females, male to female ratios for wild-derived stocks ranged from one to several hundred. Southern blots of genomic DNA hybridized to MUP subfamily probes revealed differences in restriction fragment sizes as well as possible variation in the number of MUP genes in some species. Analysis of urinary proteins from hybrids between C57BL/6 and M. spretus suggested that low MUP expression in M. spretus females was due to cis-acting genetic elements. |
