AI Article Synopsis

  • The study investigates the impact of total coumarins from Urtica dentata on colitis induced by dextran sulfate sodium in mice.
  • Mice treated with total coumarins experienced less weight loss, lower levels of inflammation markers IL-6 and IFN-gamma, and increased anti-inflammatory cytokines IL-10 and TGF-beta1.
  • The findings suggest that total coumarins have an anti-inflammatory effect, improving colitis symptoms by modulating inflammatory protein expressions and cytokine levels.

Article Abstract

Objective: To study the effect of total coumarins (TC) from Urtica dentata on dextran sulfate sodium (DSS)-induced colitis in mice.

Method: The colitis model was established by administering DSS. Having been treated with TC, their body weight was determined. Concentrations of IL-6, IL-10, TGF-beta1 and IFN-gamma were monitored by ELISA. Colon samples were collected for the histopathological examination. Western blot was used to detect TLR4 and NF-kappaB protein expression in colonic tissues.

Result: TCs from U. dentata effectively controlled the body weight loss of mice with colitis, down-regulated the concentration of IL-6 and IFN-gamma and increased the suppressive cytokines IL-10 and TGF-beta1 in the serum. Additionally, TC alleviated the mucosal damage and decreased the expressions of TLR4 and NF-kappaB in colonic tissues.

Conclusion: TCs from U. dentata shows the anti-inflammatory effect on colitis in mice by reducing the expressions of TLR4 and NF-kappaB in colonic tissues and regulating pro-and anti-inflammatory cytokines.

Scopoletin alleviates acetaminophen-induced hepatotoxicity through modulation of NLRP3 inflammasome activation and Nrf2/HMGB1/TLR4/NF-κB signaling pathway.

Scopoleitin (SP), a bioactive compound from many edible plants and fruits, exerts a wide range of biological activities, however the role and mechanism of SP in acetaminophen (APAP)-induced hepatotoxicity remains unclear. In this study, we verified the protective effect of SP on APAP-induced liver injury (AILI) hepatotoxicity and explore the underlying molecular mechanisms. Here, we showed that SP alleviated AILI by reducing serum alanine transaminase (ALT) and aspartate aminotransferase (AST) levels, hepatic histopathological damage, inflammation, and liver cell apoptosis.

Purpose: Rose Bengal Photodynamic Therapy (RB-PDT) offers dual therapeutic benefits by enhancing corneal stiffness and providing antibacterial activity, presenting significant potential for patients with keratoconus complicated by keratitis. Our purpose was to assess the effect of rose bengal photodynamic therapy (RB-PDT) on the expression of pro-inflammatory cytokines and chemokines, as well as on extracellular matrix (ECM)-related molecules, in lipopolysaccharide (LPS)-induced inflammation of keratoconus human corneal fibroblasts (KC-HCFs). Additionally, the involvement of the mitogen-activated protein kinase (MAPK) and nuclear factor kappa B (NF-κB) signaling pathways which are downstream of the Toll-like receptor 4 (TLR4) pathway were examined.

Herbicides such as paraquat (PQ) are frequently utilized particularly in developing nations. The present research concentrated on the pulmonary lesions triggered by PQ and the beneficial effect of the angiotensin receptor neprilysin inhibitor (ARNI), sacubitril/valsartan, against such pulmonary damage. Five groups of rats were established: control, ARNI, PQ (10 mg/kg), ARNI 68 + PQ, and ARNI 34 + PQ.

Aim: The aim of the current study was to investigate the potential therapeutic effect of kaurenoic acid (KA) against Monosodium Urate Crystals (MSU)- induced acute gout by downregulation of NF-κB signaling pathway, mitigating inflammation and oxidative stress produced by MSU crystals. KA potentially targeted NF-κB pathway activation and provided comprehensive insights through multiple approaches. This was accomplished by advanced analytical techniques.
