Abstract

BACKGROUND

The liver and kidney inflammation due to bacterial infection is one of the most common pathological problems leading to tissue damage or disease. In many liver and kidney disorders, which represent serious global health burden with a high economic cost, oxidative stress-related inflammation and apoptosis are important pathogenic components, finally resulting in acute liver and/or kidney failure. Erythropoietin and its analogues are well known to influence the interaction between apoptosis and inflammation in liver and kidney.

OBJECTIVE

The aim of the present study is to investigate and clarify the effect of Gromphadorhina oblongata red algae on lipopolysaccharides (LPS)-induced acute liver and kidney injury of mice with endotoxemia and associated molecular mechanism from inflammation, apoptosis and oxidative stress levels.

RESULTS

The current study cleared out that treatment of rats with the G. oblongata extract prior to LPS injection significantly lowered serum cytokines, including NF-κB, MPO and LPO, and improved liver apoptosis through suppressing protein tyrosine kinase signaling pathway, and that may be due to antibacterial activity as well antioxidant capacity of G. oblongata extract.

CONCLUSION

The present study was cleared out the possibility of administration of G.oblongata red algae as a multi products source for biotechnological, medical, nutraceutical and pharmaceutical applications due to highly antioxidant and anti-inflammatory capacities even although more investigations are required for separating, purifying and characterizing these bioactive compounds.

摘要

背景

细菌感染引起的肝、肾炎症是导致组织损伤或疾病的最常见病理问题之一。在许多肝、肾疾病中,氧化应激相关的炎症和细胞凋亡是重要的致病因素,最终导致急性肝和/或肾衰竭。促红细胞生成素及其类似物已被证明能影响肝、肾中细胞凋亡和炎症的相互作用。

目的

本研究旨在探讨并阐明圆田螺红藻对脂多糖(LPS)诱导的内毒素血症小鼠急性肝、肾损伤的影响及其相关分子机制,从炎症、凋亡和氧化应激水平上阐明其作用。

结果

本研究表明,圆田螺提取物在 LPS 注射前对大鼠进行治疗,可显著降低血清细胞因子(包括 NF-κB、MPO 和 LPO),通过抑制蛋白酪氨酸激酶信号通路,改善肝凋亡,这可能是由于圆田螺提取物具有抗菌活性和抗氧化能力。

结论

本研究表明,圆田螺红藻具有作为生物技术、医学、营养保健品和制药应用的多产品来源的可能性,尽管需要进一步分离、纯化和表征这些生物活性化合物。
