The fatty liver dystrophy (fld) mutant mouse is characterized by neonatal fatty liver and hypertriglyceridemia that resolve at weaning, and neuropathy affecting peripheral nerve in adulthood. We now report additional significant manifestations of this single gene mutation, which include adipose tissue deficiency, glucose intolerance, and increased susceptibility to atherosclerosis. In adult fld/fld mice, both white and brown fat pads exhibit an 80% reduction in mass compared with wild-type controls, and consist of immature adipocytes as assessed by morphological and molecular criteria. The lack of lipid accumulation in fld/fld adipose tissue could be attributed, in part, to a failure to induce expression of lipoprotein lipase and enzymes involved in fatty acid synthesis, such as fatty acid synthase and acetyl-CoA carboxylase. Related to the deficiency of adipose tissue, fld/fld mice were also found to exhibit profound glucose intolerance, modest hyperinsulinemia, and reduced tissue response to insulin. As insulin resistance is a important risk factor in vascular disease, we examined susceptibility of fld/fld mice to diet-induced atherosclerosis. Mutant mice fed an atherogenic diet developed 2-fold greater aortic lesions than their wild-type counterparts, despite having a less atherogenic lipoprotein cholesterol profile. The fld adipose-deficient phenotype has both similarities to and distinctions from the group of rare human diseases known as lipodystrophies.
