The mouse promoter was used to drive liver-specific expression of the mouse cDNA. Two lines were created (1 and 2) that result in 50-fold, and 150-fold, respectively, higher expression of the transcript compared to in wild-type mice. The two lines exhibit virtually identical changes in fasting serum beta-hydroxybutyrate, triglyceride, total cholesterol, glucose, and insulin concentrations. Line 1 was selected as the representative line. (J:129855)
