1 Expression of the murine liver stearoyl-CoA desaturase gene (SCD1) is induced upon feeding fasted mice a fat-free, high carbohydrate diet (Ntambi, J. M., Buhrow, S. A., Kaestner, K. H., Christy, R. J., Sibley, E., Kelly, T. J., and Lane, M.D. Carbohydrates stearoyl-Coenzyme A desaturase 1 Mus musculus
2 Based on the time course of induction, the SCD1 mRNA increased from 2-fold within 6 h to 45-fold within 36 h. Nuclear run-on transcription studies showed that the accumulation of SCD1 mRNA after refeeding starved mice a fat-free, high carbohydrate diet was a consequence of the transcriptional activation of the SCD1 gene. Carbohydrates stearoyl-Coenzyme A desaturase 1 Mus musculus
3 Based on the time course of induction, the SCD1 mRNA increased from 2-fold within 6 h to 45-fold within 36 h. Nuclear run-on transcription studies showed that the accumulation of SCD1 mRNA after refeeding starved mice a fat-free, high carbohydrate diet was a consequence of the transcriptional activation of the SCD1 gene. Carbohydrates stearoyl-Coenzyme A desaturase 1 Mus musculus
4 Based on the time course of induction, the SCD1 mRNA increased from 2-fold within 6 h to 45-fold within 36 h. Nuclear run-on transcription studies showed that the accumulation of SCD1 mRNA after refeeding starved mice a fat-free, high carbohydrate diet was a consequence of the transcriptional activation of the SCD1 gene. Carbohydrates stearoyl-Coenzyme A desaturase 1 Mus musculus
5 The SCD1 mRNA level decreased rapidly (t1/2 = approximately 4 h) within 24 h when mice fed the fat-free, high carbohydrate diet were switched to a regular chow diet. Carbohydrates stearoyl-Coenzyme A desaturase 1 Mus musculus
6 These data demonstrate that both dietary carbohydrates and polyunsaturated fatty acids or their metabolites directly or indirectly regulate the expression of the SCD1 gene in mouse liver. Carbohydrates stearoyl-Coenzyme A desaturase 1 Mus musculus
