Figure 3

Summary of gene expression during pregnancy and lactation by functional class. Adipocyte specific genes decline throughout pregnancy and early lactation while milk protein genes as a class increase over the same time period. The expression of other classes is stable during pregnancy, possibly representing expression in both the adipose and epithelial compartment and increases two- to three-fold (fatty acid and cholesterol synthesis) or decreases about two-fold (fatty acid and protein degradation) at parturition. Adipocyte genes, red; β-oxidation genes, navy blue; proteosome genes, teal; milk protein genes, brown; fatty acid biosynthesis genes, light brown; cholesterol biosynthetic genes, pink.
