The transcription and mRNA levels of murine liver stearoyl-CoA desaturase 1 (SCD1) are induced 11- and 45-fold, respectively, by feeding fasted normal mice with a fat-free, high carbohydrate diet (Ntambi, J. M. (1992) J. Biol. Chem. 267, 10925-10930). In this study, we used streptozotocin-induced diabetic mice to study the regulatory role of carbohydrate and insulin on expression of the SCD1 gene in liver. Fructose administration to fasted diabetic mice induced a 2-fold increase in SCD1 mRNA within 6 h and a 23-fold increase within 24 h. Similarly, insulin administration to diabetic mice induced SCD1 mRNA from 4-fold within 4 h to 22-fold within 24 h. Insulin plus fructose, however, achieved full induction, with a 45-fold increase of SCD1 mRNA and a 10-fold increase in SCD1 transcription within 24 h. Additionally, the effect of insulin on SCD1 mRNA was inhibited 75% with dibutyryl-cAMP and theophylline administration and 70% by cycloheximide administration. Synthesis of liver albumin mRNA showed little change upon dietary manipulation or insulin treatment. Our data demonstrate that insulin and dietary fructose or a metabolite of fructose positively regulate the expression of the SCD1 gene in mouse liver.
