| Research Abstract |
LDL receptor disrupted mice (LDLRKO) were known as a model of atherosclerosis with disturbance of lipoprotein clearance from blood. But when the syntheses of lipid were suppressed in LDLRKO mice, that the atherosclerosis would be improved or not were unknown. We investigated SREBP-1 knockout mice on the background of LDLRKO, as the model of suppressed lipid syntheses. When these models were fed Western diet, they revealed that SREBP-1 deficit could decrease in cholesterol or triglyceride levels, in plasma or VLDLs, and also suppress atherosclerosis formation or secrease in the particle size of VLDLs.
These results suggest that suppression of SREBP-1 could be a therapeutic target of atherosclerosis, especially in those who intake excessive high-calorie diets.
