Dietary cholesterol and estrogen administration elevate brain apolipoprotein E in mice by different mechanisms.
Apolipoprotein (apo) E plays an important role in the whole body cholesterol homeostasis. Recent studies suggest that it may also be involved in the local cholesterol transport in the brain, and influence the pathogenesis of Alzheimer's disease (AD) by interacting with the beta-amyloid protein and brain lipoprotein receptors. Since apoE expression is highest in the brain, next only to the liver...
متن کاملApolipoprotein E regulates dietary cholesterol absorption and biliary cholesterol excretion: studies in C57BL/6 apolipoprotein E knockout mice.
The present study examined the role of apolipoprotein E (apoE) in the regulation of dietary cholesterol absorption and biliary cholesterol excretion. Increasing dietary cholesterol from 0.02% to 0.5% in C57BL/6 wild-type mice decreased the percentage of dietary cholesterol that is absorbed by 25%, and this decrease was associated with a 2-fold increase in gallbladder biliary cholesterol concent...
متن کاملResveratrol protects against diet-induced atherosclerosis by reducing low-density lipoprotein cholesterol and inhibiting inflammation in apolipoprotein E-deficient mice
Objective(s):Resveratrol (RES) is a polyphenol compound that has been shown a promising cardioprotective effect. However, some reports have yielded conflicting findings. Herein, we investigated the anti-atherosclerotic effects of RES in apolipoprotein E (apo E)-deficient mice on a high cholesterol diet. Materials and Methods: Firstly, atherosclerosis was induced by feeding a high cholesterol di...
متن کاملEstrogen reduces atherosclerotic lesion development in apolipoprotein E-deficient mice.
We have studied the effects of endogenous and exogenous estrogen on atherosclerotic lesions in apolipoprotein E-deficient mice. Female mice ovariectomized (OVX) at weaning displayed increases (P < 0.01) in fatty streak lesions in the proximal aorta and aortic sinus compared with female mice with intact ovarian function. These differences between the OVX and sham controls were apparent in both c...
متن کاملAtypical xanthomatosis in apolipoprotein E-deficient mice after cholesterol feeding.
Apolipoprotein (apo) E-deficient mice were fed a hypercholesterolemic diet for 14 weeks. Mean serum cholesterol levels rose to 37.5 mM. Upon complete necroscopy, massive xanthomatous lesions were noticed in various tissues, with a predilection for subcutaneous and peritendinous tissues, while control animals on the same diet (3.4 mM serum cholesterol) and apo E-deficient mice on a regular chow ...
