Objective: Mice bearing the autosomal recessive mutation wst express a disease syndrome of immunodeficiency, neurologic dysfunction, increased sensitivity to the killing effects of ionizing radiation, and 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 designed experiments to examine expression of a variety of liver-specific genes in wst/wst mice relative to littermates (wst/-) and parental strain (BCF,) controls.Method: Animals were individually weighed from ages 21-28 days to determine relative weight comparisons between wst/wst mice and controls. Dot blot hybridizations were set up to quantitate the accumulation of transcripts specific for a-fetoprotein, albumin and other liver-specific gene products.Results: These results showed a 67% reduction in albumin mRNA expression in livers derived from wst/wst mice relative to both controls. Expression of a-fetoprotein, as well as a variety of other liver- specific genes [secretory component (SC), metallothionein (MT-2), cytochrome Pi-450 (Cyt Pi-450), transferrin receptor (Tf Rec), tumor necrosis factor (TNF), and immune-associated antigen (la)], was unaffected.Conclusions: These results suggest a relationship between low albumin expression and wasting syndromes in mice. In addition, our data suggest that the wasted mouse may serve as a unique model for subnormal albumin expression.
