Imagine you have a group of 549 participants, half of whom have Alzheimer’s Disease (AD) and the other half are healthy controls. You want to understand how the APOE gene and lipid profiles differ between these two groups, taking into account the influence of sex. After analyzing the data, it was found that total cholesterol (TC) and low-density lipoprotein (LDL) levels were higher in AD patients compared to healthy controls, but only in those who carried the APOEε4 allele, not in non-carriers. Additionally, TC and LDL levels were higher in APOEε4 carriers with AD compared to APOEε4 carriers without AD. On the other hand, male AD patients who carried the APOEε2 allele had lower TC levels compared to non-carriers, while this difference was not observed in female AD patients or healthy controls. These findings suggest that the effects of APOE gene on lipid profiles differ based on sex and disease status. Interestingly, there is evidence that high LDL levels may increase the risk of developing AD in females with the APOEε4 allele. To delve deeper into this study and explore the complex relationship between sex, genes, lipid profiles, and Alzheimer’s Disease, check out the full article!
BackgroundSex is an important factor in studying the relationship between the APOE gene, lipid profiles, and AD. However, few studies have focused on the effect of sex on lipids in AD and normal controls with different APOE genes.Materials and MethodsA total of 549 participants, including 298 AD patients and 251 body mass index (BMI)-matched healthy controls (HCs), were enrolled. Lipid profiles and APOE genes in both AD patients and HCs were determined.Results(1) TC and LDL were higher in AD patients than in HCs, only in APOEε4 carrying populations, but not in non-carrying populations. (2) TC and LDL were higher in APOEε4 allele carriers than in non-carriers, only in AD populations, but not in HCs. (3) The TC of APOEε2 carriers was lower than that of non-carriers in the male AD population, but not in the female AD population, female HCs, and male HCs. (4) The increased LDL level may increase the risk of AD in female people carrying APOEε4.ConclusionThe TC and LDL levels of APOEε4 carriers were higher than those of non-carriers, and the effect was more significant in the female AD population. The TC levels in APOEε2 carriers were lower than those in non-carriers, which was more significant in the male AD population.
