摘要

该研究旨在探讨鱼油补充剂对ApoE缺乏（ApoE-/-）小鼠和野生型C57BL/6J （C57 wt）小鼠脑脂质谱的影响，这些小鼠在饮食中含有不同剂量的维生素E （VE）。与C57小鼠相比，ApoE-/-小鼠皮层TC和LDL-C水平升高，HDL-C水平降低（P < 0.05）。鱼油干预结合低VE饮食摄入导致C57 wt小鼠皮质蛋白CD36和PPARγ表达增加。在C57 wt和ApoE-/-小鼠中，与对照组相比，PI（36:5）被鉴定为显著不同的代谢物。鱼油和不同剂量VE联合使用对ApoE-/-和C57 wt小鼠脑脂质和脂肪酸转运蛋白的表达有不同的影响，表明ApoE状态和膳食VE摄入量影响了脑脂质谱对鱼油补充的反应。

Impact of fish oil supplement on brain lipids profile in ApoE-/- mice and C57BL/6 J mice treated with diets containing different dosage of vitamin E

The study was designed to explore the impact of fish oil supplement on the brain lipids profile in ApoE-deficient (ApoE-/-) mice and wild-type C57BL/6 J (C57 wt) mice treated with diets containing varying dosage of vitamin E (VE). Compared to C57 wt mice, ApoE-/- mice exhibited increased cortical TC and LDL-C levels, but decreased HDL-C level (P<.05). The fish oil intervention, combined with low dietary VE intake resulted in increased cortical protein expression of CD36 and PPARγ in C57 wt mice. PI (36:5) was identified as a significantly different metabolite when compared to the control group in both C57 wt and ApoE-/- mice. The combination of fish oil and varying doses of VE had different effects on the expression of brain lipids and fatty acid transporters in ApoE-/- and C57 wt mice, indicating that ApoE status and dietary VE intake influence the responses of the cerebral lipids profile to fish oil supplementation.
