  • 功能:
    Mediates the binding, internalization, and catabolism of lipoprotein particles. It can serve as a ligand for the LDL (apo B/E) receptor and for the specific apo-E receptor (chylomicron remnant) of hepatic tissues.
  • 基因功能参考文献:
    1. Infusion of AngII did not lead to the formation of dissecting abdominal aortic aneurysms or atherosclerosis in ApoE-knockout rats.
    2. Results demonstrated that apolipoprotein E4 (ApoE4)exerted direct neurotoxicity and enhanced the neurotoxicity of Abeta1-40 on spatial cognitive function and hippocampal long term potentiation. This may partly elucidate the mechanism by which APOE4 allele exerted negative effects as a major genetic risk factor for developing Alzheimer's disease.
    3. renal denervation improves aortic distensibility and attenuated endothelial dysfunction in ApoE(-/-)-rats.
    4. The expression of ApoE and S-100 correlated with the progression of focal cerebral contusion.
    5. Apolipoprotein E-deficient rats develop atherosclerotic plaques in partially ligated carotid arteries.
    6. rats treated with KD (EXP2) showed a significant down-regulated expression of ZnT-3, MT-3, ApoE, clusterin, and ACAT-1 in hippocampus
    7. Findings suggest that endogenous apoE generates lower density HDL to produce more lipidated HDL using previously synthesized cholesterol through the interaction with ABCA1 in caveolin-1-rich domain of astrocytes
    8. Although rat apolipoprotein E sequence resembles apoE4, an isoform of apoE3, rat apoE displays the biophysical behavior of apoE3.
    9. A potential neuroprotective role of apolipoprotein E-containing lipoproteins through low density lipoprotein receptor-related protein 1 in normal tension glaucoma
    10. Lower expression of MMP-2 and MMP-9 is associated with the increased expression of apoE in the glomerulus
    11. ApoE-containing astrocyte lipoproteins exhibit the most robust interactions with Abeta.
    12. Apolipoproteins E3 exerts neurotrophic and synaptogenic effects in dorsal root ganglion cell cultures.
    13. LpE and LRP1 promote axonal extension, and suggest that lipids exported to LpE by ABCG1 are important for the enhancement of axonal extension mediated by LpE.
    14. ApoE may play a role in lipid rafts or synaptic structural plasticity by the regulation of its levels via dendritic localization and translation.
    15. These observations suggest that ApoE, expressed by activated retinal glia, stimulates RGC neurite outgrowth after intravitreal Zymosan injection.
    16. Although ApoE increases arterial wall accumulation of triglyceride-rich particles(TGRPs), it also reduces the penetration of TGRPs into the arterial wall--a novel antiatherogenic property.
    17. ApoE mRNA was expressed in astrocytes and macrophages, but not in neurons after focal cerebral ischemia
    18. Spatiotemporal changes of apolipoprotein E immunoreactivity and apolipoprotein E mRNA expression after transient middle cerebral artery occlusion in rat brain.
    19. The Apolipoprotein (apo) E is a protein involved in both lipid metabolism and neuroprotection and its expression system will be highly useful for probing the ability of rat apoE to mediate food intake in rats.
    20. Data indicate that the role of apoE4 in cholesterol homeostasis and apolipoprotein cell association is more pronounced in hippocampal neurons.
    21. Our studies suggest that AEC I is not just a simple barrier for gas exchange, but a functional cell that protects alveolar epithelium from injury.
    22. 24(S)-hydroxycholesterol induces apoE-mediated efflux of cholesterol in astrocytes via an LXR-controlled pathway
    23. ApoE expression is not altered during normal brain aging, but there may be a relationship between ApoE and IL-1beta transcription in the cerebral cortex
    24. LRP binds and endocytoses Abeta42 both directly and via apoE but endocytosed Abeta42 is not completely degraded and accumulates in intraneuronal lysosomes
    25. A naturally processed C-terminal ApoE peptide, Ep1.B, has anti-atherogenic activity indicating a role for this naturally metabolized peptide in vascular wound healing and lipid homeostasis
    26. treatment of primary rat mixed glial cell cultures with IL-1beta induced a significant increase in extracellular apoE protein; treatment of primary astrocyte and mixed glial cell cultures with TNF-alpha significantly reduced extracellular apoE
    27. mRNA expression of ApoE in arterial walls was not different between the controls and cerebral aneurysms.
    28. Data demonstrate that apoE suppresses food intake via a mechanism enhancing melanocortin signaling in the hypothalamus.
    29. The finding that hypothalamic apoE and food intake are positively associated during the normal circadian cycle as well as in the period of restricted feeding suggests that hypothalamic apoE is food-entrained and regulates food intake.
    30. Protection of neurons from apoptosis by apolipoprotein E-containing lipoproteins does not require lipoprotein uptake and involves activation of phospholipase Cgamma1 and inhibition of calcineurin.
