Abstract:BACKGROUND: Sea cucumber phospholipids, marine-derived lipids with high nutritional functions, have been proven to exhibit various biological activities.然而,尚不清楚海洋磷脂如何调节动脉粥样硬化中的胆固醇(CHOL)代谢。
目的: 这项研究旨在研究对库糖菌的影响和机械机制的磷酸盐疗法(磷酸磷酸磷酸盐)的效果和机械机制( 在ApoEmice, including plasmenyl phosphatidylethanolamine (PE-P) and plasmanyl phosphatidylcholine (PC-O).
METHODS: Male ApoEmice were fed with Chow diet, high-fat diet (HFD), and HFD supplemented with PC-O or PE-P, 分别。我们集成了靶向脂质组学策略,以根据其脂肪酸类型进行分类和比较胆固醇酯,然后分析小鼠的肝脏和血清中的单个胆汁固醇酯分子物种。 Furthermore, the Chol metabolism-related genes and pathways were analyzed in high-fat-induced ApoEmice.
RESULTS: Biochemical analysis showed that sea cucumber phospholipids significantly inhibit the generation of arterial plaque in ApoEmice.与HFD组相比,PE-P显着降低了小鼠肝脏中SFA-CE和MUFA-CE的含量(p <0.05),而PC-O在Seru中尤其上调CE20:5和CE22:6小鼠的m(p <0.001)。此外,PC-O和PE-P抑制了CHOL合成途径(CYP7A1和CYP27A1),并通过上调胆汁酸合成(ABCB11)和溶酶体活性(lamp1)的基因表达来促进CHOL的分解代谢。 海参磷脂可以通过调节CHOL代谢来改善动脉粥样硬化症状。 J Nutr 20xx; x:xx。
