Immature ovaries and polycystic kidneys in the congenital polycystic kidney mouse may be due to abnormal sex steroid metabolism
2001
Abstract Ke 6 is a 17β-hydroxysteroid dehydrogenase (17βHSD) that is expressed in the kidneys and gonads. The expression of this gene is markedly reduced in three murine models of recessive polycystic kidney disease, a developmental disorder, where some nephrons within the affected kidneys develop into huge fluid-filled cysts while the non-cystic nephrons atrophies by apoptosis. Here, we show that in the cpk/cpk mouse, which have polycystic kidneys, the female reproductive organs also fail to mature properly and remain arrested at an early stage of development. Direct measurement of 17βHSD activity showed a severe reduction in estrogen and androgen metabolism within gonadal and non-gonadal tissues of the cpk/cpk mouse. Using immunofluorescent staining we localized the expression of the Ke 6 protein within the female mouse reproductive organs. Our findings suggest that estrogen/androgen metabolism may play an important role in the development of the urogenital systems.
