dc.description.abstract | Elongation of very long chain fatty acids protein 6 (ELOVL6), a rate-limiting enzyme for the elongation of saturated and monounsaturated fatty acids with 12, 14, and 16 carbons, plays a key role in energy metabolism and insulin sensitivity. Hepatic Elovl6 expression is upregulated in the fasting-refeeding response and in leptin-deficient ob/ob mice. Mouse Elovl6 has been shown to be a direct target of sterol regulatory element binding protein-1 (SREBP-1) in response to insulin. In the present study, we demonstrated that mouse and human Elovl6 expression is under the direct transcriptional control of carbohydrate response element binding protein (ChREBP), a mediator of glucose-induced gene expression. Serial deletion and site-directed mutagenesis studies revealed functional carbohydrate response elements (ChoREs) in the mouse and human Elovl6 promoters and gel shift assays and chromatin immunoprecipitation assays confirmed the binding of ChREBP to the Elovl6-ChoRE sites. In addition, the ectopic co-expression of ChREBP and SREBP-1c in HepG2 cells synergistically stimulated Elovl6 promoter activity and this synergistic activation was abolished by mutating the Elovl6 promoter ChoREs. Taken together, these results suggest that the synergistic action of ChREBP and SREBP-1c is necessary for the maximal induction of Elovl6 expression in the liver. (C) 2016 Elsevier Inc.
