载脂蛋白 E4 (APOE4) 基因型可预测阿尔茨海默病 (AD)。大脑富含 omega-3 多不饱和脂肪酸 (n3-PUFA)、二十二碳六烯酸 (DHA)。 APOE4 携带者的 DHA 代谢存在缺陷。黄烷醇的摄入可以起到调节 DHA 水平的作用。然而,黄烷醇与鱼油共同补充对大脑 DHA 吸收、状态和分配以及 APOE 基因型的影响目前尚不清楚。在这里,使用人源化 APOE3 和 APOE4 靶向替代转基因小鼠模型,研究了补充富含鱼油 (FO) 中的 DHA 的高脂肪 (HF) 后,可可黄烷醇 (FLAV) 和 APOE 基因型对血液和皮层下大脑 PUFA 状态的相互作用影响。补充后,血液 (p < 0.001) 和大脑 (p = 0.001) 中的 DHA 水平增加。与 APOE3 相比,补充 FO 和 FLAV 后,APOE4 小鼠的红细胞 (RBC) DHA 明显升高 (p < 0.001)。尽管 FO 没有增加 APOE4 中脑 DHA 的百分比,但 HF FO 和 HF FO FLAV 组中磷脂酰胆碱 (PC) 组分中的 DHA 水平分别提高了 17.1% (p < 0.05) 和 20.0% (p < 0.001),并且 HF FO FLAV 组中磷脂酰乙醇胺 (PE) 组分中的 DHA 水平提高了 14.5% (p < 0.05)。相对于 HF 对照组,这些动物中 HF FO FLAV 组的情况很明显。添加 FLAV (+/- FO) 并没有显着增加整个组中大脑 DHA 的百分比。然而,与 HF 相比,HF FLAV 仅在 APOE3 中明显具有较高的大脑:RBC DHA 比率 (p < 0.05)。总之,我们的数据显示 FLAV 对大脑 DHA 状态的影响不大,仅限于 APOE3。
The apolipoprotein E4 (APOE4) genotype is predictive of Alzheimer’s disease (AD). The brain is highly enriched with the omega-3 polyunsaturated fatty acid (n3-PUFA), docosahexaenoic acid (DHA). DHA’s metabolism is defective in APOE4 carriers. Flavanol intake can play a role in modulating DHA levels. However, the impact of flavanol co-supplementation with fish oil on brain DHA uptake, status and partitioning, and according to APOE genotype is currently unknown. Here, using a humanised APOE3 and APOE4 targeted replacement transgenic mouse model, the interactive influence of cocoa flavanols (FLAV) and APOE genotype on the blood and subcortical brain PUFA status following the supplementation of a high fat (HF) enriched with DHA from fish oil (FO) was investigated. DHA levels increased in the blood (p < 0.001) and brain (p = 0.001) following supplementation. Compared to APOE3, a higher red blood cell (RBC) DHA (p < 0.001) was evident in APOE4 mice following FO and FLAV supplementation. Although FO did not increase the percentage of brain DHA in APOE4, a 17.1% (p < 0.05) and 20.0% (p < 0.001) higher DHA level in the phosphatidylcholine (PC) fraction in the HF FO and HF FO FLAV groups, and a 14.5% (p < 0.05) higher DHA level in the phosphatidylethanolamine (PE) fraction in the HF FO FLAV group was evident in these animals relative to the HF controls. The addition of FLAV (+/− FO) did not significantly increase the percentage of brain DHA in the group as a whole. However, a higher brain: RBC DHA ratio was evident in APOE3 only (p < 0.05) for HF FLAV versus HF. In conclusion, our data shows only modest effects of FLAV on the brain DHA status, which is limited to APOE3.
