additional information | generation of tissue-specific SOAT2 knockouts in liver and small intestine, i.e. SOAT2L-/L- and SOAT2SI-/SI- mice, phenotypes, overview. Floxed mice (LoxP sites flanked exons 11 through 13 of the SOAT2 gene on chromosome 15) are designated as SOAT2fl/fl. SOAT2 wild-type control mice (SOAT2+/+LDLr?/?) and SOAT2 floxed mice (SOAT2fl/flLDLr?/?) have similar levels of cholesterol absorption. SOAT2 total body knockout mice (SOAT2?/?LDLr?/?) and intestinal SOAT2 knockout mice (SOAT2SI?/SI?LDLr?/?) have significantly decreased levels of cholesterol absorption, overview. SOAT2 knockout mice have lower plasma VLDL and LDL cholesterol concentrations | Mus musculus |

malfunction | aortic atherosclerosis development is significantly lower in all mice with global or tissue-restricted SOAT2 gene deletions. Nevertheless, liver-specific and complete SOAT2-/-LDLr-/- knockout mice have less aortic cholesterol esters accumulation and smaller aortic lesions than intestine-specific SOAT2SI-/SI-LDLr-/- mice | Mus musculus |
physiological function | cholesterol esters, especially cholesterol oleate, generated by hepatic and intestinal sterol O-acyltransferase 2 (SOAT2) play a critical role in cholesterol homeostasis. SOAT2-derived cholesterol esters from both the intestine and liver significantly contribute to the development of atherosclerosis, although the cholesterol esters from the hepatic enzyme appear to promote more atherosclerosis development. Intestinal SOAT2, but not liver SOAT2, is a critical determinant of cholesterol absorption and of biliary cholesterol levels | Mus musculus |
