1 Alpha-linolenic acid increases cholesterol efflux in macrophage-derived foam cells by decreasing stearoyl CoA desaturase 1 expression: evidence for a farnesoid-X-receptor mechanism of action. alpha-Linolenic Acid stearoyl-CoA desaturase Homo sapiens
2 This study investigated the mechanisms by which ALA regulated SCD1 and subsequent effect on cholesterol storage and transport in MDFCs. alpha-Linolenic Acid stearoyl-CoA desaturase Homo sapiens
3 Alpha-linolenic acid treatment and SCD1 siRNA significantly decreased SCD1 expression in MDFCs. alpha-Linolenic Acid stearoyl-CoA desaturase Homo sapiens
4 Alpha-linolenic acid activated the nuclear receptor farnesoid-X-receptor, which in turn increased its target gene small heterodimer partner (SHP) expression, and decreased liver-X-receptor dependent sterol regulatory element binding protein 1c transcription, ultimately resulting in repressed SCD1 expression. alpha-Linolenic Acid stearoyl-CoA desaturase Homo sapiens
5 In conclusion, repression of SCD1 by ALA favorably increased cholesterol efflux and decreased cholesterol accumulation in foam cells. alpha-Linolenic Acid stearoyl-CoA desaturase Homo sapiens
