Hypercholesterolemia is a complex disorder plausibly hipercholesterolemia diet rat by complex genetic networks. Atherosclerotic heart disease is the leading cause of death in the world and is projected to remain the single leading cause of death by [ 98 ]. Recent studies have shown, that high cholesterol levels are linked to the pathology of AD.
Zusammen mit Lipiden Fette: Dieser Vorgang wird Cholesterinbiosynthese genannt. These baboons have been used to develop nonhuman primate genomic resources to study responses to environmental factors, such as diet, and how these factors hipercholesterolemia diet rat with genomic factors in causing complex diseases or disorders.
Numerous animal species have been used as animal models for investigating hypercholesterolemia, including rabbits [ 56 ], mice [ 7 ], guinea pigs [ 8 ], minipigs [ 9 ], laboratory opossums [ 10 ] and nonhuman primates [ 11 - 15 ].
Studies using genetically modified mice have shown that they are indispensable for advancing our knowledge of the genes and pathways that govern cholesterol homeostasis, as well as for developing pharmacological agents to treat atherosclerosis.
Furthermore, analysis of lipoprotein particles by gradient gel electrophoresis showed elevated levels of LDL particles in high responding opossums [ 22 ].
Monodelphis is omnivorous like humans, and its natural diet includes cholesterol derived from the consumption of insects and small vertebrates. However, extensive use of the collage of primate and non-primate models has provided considerable insights into the genes and molecular mechanisms that control plasma cholesterol in response to diets.
Sterol hydroxylase is an important enzyme for bile acid synthesis in both the classic and alternate pathways. Variation among species.
Nonhuman primates are more similar to humans than other animals, but ethical issues, facilities and high cost limit studies with nonhuman primates. For cancer cells to proliferate uncontrollably, essential cell components, such as cholesterol must be available for plasma membrane synthesis.
Furthermore, in AD brains chronic inflammatory responses including microglial activation have been detected Akiyama et al.
Using a pedigree-based genetic association approach, matings of high responders with low responders were carried out to produce F2 progeny in two different crosses designated JCX and KUSH6 to determine whether ABCB4 has an effect on response to dietary cholesterol.
Initial events during atherogenesis include deposition of modified or oxidized cholesterol ox-cholesterol in the artery wall, resulting in endothelial dysfunction; adhesion of circulating monocytes onto the endothelium; entry of ox-cholesterol and monocytes into the intima layer of the artery; engulfment of ox-cholesterol by monocytes and transformation into macrophages and foam cells; production of pro-inflammatory cytokines and connective matrix; conversion and proliferation of smooth muscle cells; cell apoptosis; and intima thickening.
ABCB4 mutations affect secretion of phospholipids, and clinical symptoms are due to production of bile with a low phospholipid content which cannot prevent bile salts from damaging the membranes of cells lining the bile ducts.
Therefore, expression of cholesterol and phospholipid transporter genes cannot explain differences in biliary lipid concentrations. Nerve growth factor was only slightly enhanced in the cortex of cholesterol-treated animals. Biliary phospholipid secretion in the liver serves two purposes.
Identification of these variations is essential for genetic analysis to develop novel therapeutic agents for lowering plasma cholesterol and biomarkers for detection of early atherosclerosis, a precursor for cardiovascular disease.
ABCB11 plays a central role in hepatobiliary secretion as bile flow is the driving force for biliary secretion of cholesterol and phospholipids [ 43 ].
Moreover, the phospholipid deficient bile has a high cholesterol saturation index. In the liver, the LDL receptor regulates plasma cholesterol by binding to apoB and apoE on the surface of lipoprotein particles and removes these particles from the plasma [ 32 ].
However, high responding opossums exhibit an extremely high LDL cholesterol response when fed an HCHF diet compared to low responding opossums. In addition, genetic factors influence susceptibility to diet-induced hypercholesterolemia. Animals from both crosses were genotyped for the ABCB4 IleLeu polymorphism and subjected to measured genotype analysis using plasma cholesterol data from a basal diet and from a 4-week HCHF diet.
This is because nonhuman primates and humans share similar biochemical, anatomical and physiological characteristics, including lipid synthesis and metabolism.Kidney International, Vol. 37 (), pp. — Renal injury of diet-induced hypercholesterolemia in rats BERTRAM L.
