Subnormal albumin gene expression is associated with weight loss in immunodeficient/DNA-repair-deficient wasted mice

Mice bearing the autosomal recessive mutation wst express a disease syndrome of immunodeficiency, neurologic dysfunction, and increased sensitivity to the killing effects of ionizing radiation. The mice were originally characterized as ``wasted`` because of their dramatic weight loss that begins at 21 days of age and progresses until death at 28-32 days of age. Because of the reported association between abnormal liver status and weight loss, we examined expression of a variety of liver-specific genes in wst/wst 10 mice relative to littermate (wst/{center_dot}) and parental strain (BCF{sub 1}) controls. Interestingly, the results revealed a greater than 67% reduction in albumin mRNA expression in livers derived from wst/wst mice relative to both controls. Expression of alpha-fetoprotein as well as a variety of other liver-specific genes (secretory component, metallothionein, cytochrome P{sub 1}450, transferrin receptor, tumor necrosis factor, and Ia antigen) was unaffected. These results suggest a relationship between low albumin expression and wasting syndromes in mice. In addition, we believe that our data suggest the wasted mouse as a unique model for subnormal albumin expression in humans.
