Detailed Document
Overview of Gene Research
Apoe, encoding apolipoprotein E, is a major apolipoprotein involved in lipoprotein metabolism, contributing to lipid homeostasis [2]. It is a polymorphic protein with three main alleles ε4, ε3, and ε2 at a single locus, which are associated with various biological processes and diseases.
The APOE ε4 allele is the strongest genetic risk factor for sporadic Alzheimer's disease, while the ε2 allele is the strongest genetic protective factor [1]. In Alzheimer's disease, APOE pathogenesis involves amyloid-β peptide aggregation and clearance, tau neurofibrillary degeneration, microglia and astrocyte responses, and blood-brain barrier disruption [1].
In primary dyslipidemia, apoE4 is associated with increased LDL-cholesterol levels and higher cardiovascular risk, while apoE2 may be associated with a mild decrease in LDL-cholesterol levels. Some rare APOE gene variants are related to different types of dyslipidemias [2].
In glaucoma, APOE4 and APOE gene deletion (APOE-/ -) can reduce retinal ganglion cell (RGC) loss, while APOE3 and the overall presence of APOE genes (APOE + / + ) increase the risk of glaucoma RGC death [3].
In conclusion, Apoe plays a crucial role in lipid metabolism and is associated with multiple diseases such as Alzheimer's disease, primary dyslipidemia, and glaucoma. Studies on Apoe, including those using gene knockout models, help us understand its role in these disease-related biological processes, providing potential directions for disease prevention and treatment.
