Epidemiological studies have demonstrated that hypercholesterolemia is associated with an elevated risk of atherosclerosis and cardiovascular diseases. In addition to the available cholesterol-lowering drugs, nutritionally balanced diets containing functional foods have attracted much interest as potential candidates to improve hypercholesterolemia. In the study, we demonstrated that dietary succinoglycan riclin effectively alleviated diet-induced hypercholesterolemia. Compared with the high-cholesterol-diet (HCD) group, the high-riclin group significantly decreased levels of the serum total cholesterol, low-density lipoprotein cholesterol (LDL-C), and hepatic cholesterol (34, 40, and 51%, respectively), consequently improving hepatic steatosis and reducing proinflammatory cytokine expressions. 1H nuclear magnetic resonance (NMR)-based lipidomics and metabolomics analyses revealed that the riclin group partially reversed metabolic profile changes induced by the HCD, approaching that of the normal diet (ND) group. Riclin has no direct effects on cholesterol metabolism-related gene expression among the three HCD model groups. Basically, riclin increased the solution viscosity and interfered in the process of bile acid-cholesterol emulsification, decreasing cholesterol digestion and promoting cholesterol and bile acid excretion in the feces. These results suggested potential therapeutic utility of succinoglycan riclin as a food additive for people suffering from hypercholesterolemia and related diseases.

琥珀糖Riclin的口服给药可改善小鼠饮食引起的高胆固醇血症。

流行病学研究表明,高胆固醇血症与动脉粥样硬化和心血管疾病的风险升高有关。除了可用的降低胆固醇的药物外,含有功能性食品的营养均衡饮食作为改善高胆固醇血症的潜在候选者也引起了人们的极大兴趣。在这项研究中,我们证明了饮食中的琥珀聚糖蓖麻毒素可有效减轻饮食引起的高胆固醇血症。与高胆固醇饮食(HCD)组相比,高蓖麻蛋白组显着降低了血清总胆固醇,低密度脂蛋白胆固醇(LDL-C)和肝胆固醇的水平(分别为34%,40%和51%,分别),从而改善肝脂肪变性并降低促炎细胞因子的表达。基于1H核磁共振(NMR)的脂质组学和代谢组学分析表明,蓖麻毒素组部分逆转了HCD引起的代谢谱变化,接近正常饮食(ND)组的代谢谱变化。在三个HCD模型组中,Riclin对胆固醇代谢相关基因的表达没有直接影响。基本上,蓖麻毒素可增加溶液粘度并干扰胆汁酸-胆固醇的乳化过程,减少胆固醇的消化并促进粪便中胆固醇和胆汁酸的排泄。这些结果表明,琥珀聚糖蓖麻蛋白作为治疗高胆固醇血症和相关疾病的人的食品添加剂具有潜在的治疗作用。接近正常饮食(ND)组的水平。在三个HCD模型组中,Riclin对胆固醇代谢相关基因的表达没有直接影响。基本上,蓖麻毒素可增加溶液粘度并干扰胆汁酸-胆固醇的乳化过程,减少胆固醇的消化并促进粪便中胆固醇和胆汁酸的排泄。这些结果表明,琥珀聚糖蓖麻蛋白作为治疗高胆固醇血症和相关疾病的人的食品添加剂具有潜在的治疗作用。接近正常饮食(ND)组的水平。在三个HCD模型组中,Riclin对胆固醇代谢相关基因的表达没有直接影响。基本上,蓖麻毒素可增加溶液粘度并干扰胆汁酸-胆固醇的乳化过程,减少胆固醇的消化并促进粪便中胆固醇和胆汁酸的排泄。这些结果表明,琥珀聚糖蓖麻蛋白作为治疗高胆固醇血症和相关疾病的人的食品添加剂具有潜在的治疗作用。减少胆固醇的消化并促进粪便中的胆固醇和胆汁酸排泄。这些结果表明琥珀聚糖蓖麻蛋白作为治疗高胆固醇血症和相关疾病的人的食品添加剂的潜在治疗作用。减少胆固醇的消化并促进粪便中的胆固醇和胆汁酸排泄。这些结果表明,琥珀聚糖蓖麻蛋白作为治疗高胆固醇血症和相关疾病的人的食品添加剂具有潜在的治疗作用。
