Red Ginseng Reduces Inflammatory Response via Suppression MAPK/P38 Signaling and p65 Nuclear Proteins Translocation in Rats and Raw 264.7 Macrophage

Abstract

Lipopolysaccharides (LPS) cause systemic inflammatory responses, which are characterized by high mortality and multiple signs, including metabolic disturbances, respiratory acidosis, hypotension, and vital organs disorder. Cytokines secretion and oxidative stress are the main features of the disease. Diagnosis and treatment of systemic inflammation (SI) remain a challenge. Korean Red Ginseng (RG) is one of medicinal herbs that showed a potent anti-oxidant effect. We aimed to study the protective effects of RG on systemic inflammatory response in rats and RAW 264.7 macrophage cells induced by LPS. The rats were treated with water and alcohol extracts of RG for four weeks to prevent the inflammatory response. The result showed that LPS toxin increased morbidity and mortality, and induced liver, kidney, and lung injuries manifested by deteriorated biomarkers. Hypotension, hypomagnesemia, acidosis, and oxidative stress were observed in septic rats. However, RG extracts attenuated liver, kidney, and lung enzymes and metabolites in treated groups via its anti-inflammatory and anti-oxidant properties. Furthermore, RG improved magnesium and blood pressure in the treated groups. RAW 264.7 macrophage cells exposed to LPS disturbance in translocation of p65 and MAPK/p38. Nevertheless, RG-pretreated cells did not significantly alter. In conclusion, RG reduced the rates of mortality and morbidity of treated rats — liver, kidney, and lung injuries were protected in the treated groups through the potentiation of anti-oxidant defense. RG was able to conserve mitochondrial function, inhibiting the activation of MAPK/p38 signaling and suppressing NF-[Formula: see text]B p65 cytoplasm-nucleus transport. Further studies are needed to examine the effects on chronic conditions in animal models and human.

“…Many recent studies have shown its antioxidant and anti-inflammatory effects of Ginseng in the brain affected by aging-associated diseases and toxic insults such as sodium fluoride and aluminum chloride (AlCl 3 ) ( Mahaboob Basha and Saumya, 2013 ; Adam et al, 2019 ; Choi et al, 2021 ) . One of these studies investigated potencial pro-cognitive and neuroprotective effects of compound K, a metabolite of ginsenosides, present in the enzymatically hydrolyzed red ginseng extracts (HRGE).…”

Ginsenoside Compound K Attenuates Ox-LDL-Mediated Macrophage Inflammation and Foam Cell Formation via Autophagy Induction and Modulating NF-κB, p38, and JNK MAPK Signaling

“…NF-κB and MAPK are also important signaling pathways that affect foam cell aggregation and inflammatory response ( Kim and Kim, 2019 ; Shen W. et al, 2019 ). Previous studies have demonstrated that NF-κB is a key regulator of macrophage inflammation, and NF-κB inhibition reduces foam cell formation ( Plotkin et al, 2017 ; Islam et al, 2018 ; Adam et al, 2019 ; Kim and Kim, 2019 ). The current study showed that CK significantly inhibited phosphorylation of IKKβ and suppressed IκBα degradation and phosphorylation, thereby reducing the phosphorylation of NF-κB P65.…”

“…In addition, MAPK and NF-κB signaling pathways regulate inflammation ( 34 , 35 ). Several studies have demonstrated the regulatory role of MAPK and NF-κB signaling pathways in macrophages inflammation ( 36 – 38 ). To assess whether T3 and T3-lipo may regulate inflammatory levels through the MAPK and NF-κB signaling pathways, we performed a Western blotting assay.…”
