Liver gene expression profiling of lipoprotein lipase heterozygous knockout mice. Mus musculus

Lipoprotein lipase (Lpl) was predicted as a causal gene for abdominal using a novel statistical method named LCMS (Schadt et al., 2005, Nature Genetics). In order to validate this prediction, we profiled the liver tissues of lipoprotein lipase heterozygous knockout mice (Lpl+/-) and their littermate wild-type (wt) controls to examine the gene expression signature as well as pathways/networks resulting from the single gene perturbation. Overall design: 8 Lpl+/- mice and 8 wt controls were profiled. Reference pool included RNA extracted from the liver of 9 wt control mice. Dye-swap was involved in the profiling.
