Purpose: To investigate the therapeutic role of diosmetin in periodontitis and its probable mechanism action.Methods: Lipopolysaccharide (LPS) was used to induce periodontal cells. Cell viability apoptosis response LPS were evaluated using MTT TUNEL assays. The oxidative stress inflammatory responses LPS-induced effects cells detected enzyme-linked immunosorbent assay (ELISA). In addition, role...

Background: Sepsis is most likely to cause lung damage in patients, and the detection rate mortality are high. Here, we investigated expression of miR-20a sepsis-induced acute injury (ALI) rats its effect on inflammatory response, reveal possible molecular mechanism. Method: The model caused by sepsis was established cecal ligation puncture. tissue determined RT-qPCR. Acute were injected with 5...

Treatment of sickle cell disease (SCD) is hampered by incomplete understanding of pathways linking hemolysis to vaso-occlusion. We investigated these pathways in transgenic sickle mice. Infusion of hemoglobin or heme triggered vaso-occlusion in sickle, but not normal, mice. Methemoglobin, but not heme-stabilized cyanomethemoglobin, induced vaso-occlusion, indicating heme liberation is necessary...

Gastric cancer is one of the most common causes of cancer-related death worldwide. Helicobacter pylori infection plays an important role in the development and progression of gastric cancer. The expression of astrocyte-elevated gene-1 (AEG-1) is increased in gastric cancer tissues, thereby contributing to the inflammatory response. We investigated whether and how AEG-1 regulated proinflammatory...

Toll-like receptors (TLRs) are key factors in the innate immune system and initiate an inflammatory response to foreign pathogens, such as bacteria, fungi and viruses. TLR4-mediated signaling has been implicated in tumor cell proliferation and apoptosis in numerous cancers. The present study aimed to investigate the biological effect of TLR4 on the proliferation and apoptosis of human liver can...

It has been previously reported that Toll‑like receptor 4 (TLR4)/NF‑κB signaling mediates early inflammation during myocardial ischemia and reperfusion. It has additionally been suggested that resveratrol produces cardioprotective and anti‑inflammatory effects. The aim of the present study was to investigate whether resveratrol could modulate TLR4/NF‑κB signaling, reduce neutrophil accumulation...

The aim of our study was to analyze the role of toll-like receptor 4 (TLR4)/nuclear factor (NF)-κB signal pathway on Hepcidin regulation in non-alcoholic fatty liver disease (NAFLD). A total of 60 male Sprague-Dawley rats were randomly divided into the control, NAFLD and intervention groups. Rats in the control group were fed with standard laboratory diet, and rats in the NAFLD and intervention...

BACKGROUND This study aimed to investigate whether exogenous hydrogen sulfide (H2S) can protect the RAW264.7 macrophages against the inflammation induced by free fatty acids (FFA) by blunting NLRP3 inflammasome activation via a specific TLR4/NF-κB pathway. METHODS RAW264.7 macrophages were exposed to increasing concentrations of FFA for up to 3 days to induce FFA-induced inflammation. The cel...

AIMS The molecular events leading from cardiomyocyte ischaemia to inflammatory cytokine production are not well understood. We previously found that heat shock protein 60 (HSP60) appeared in extracellular space after cardiomyocyte ischaemia. This study examined the activation and regulation of toll-like receptors (TLRs) by HSP60 in cardiomyocytes. METHODS AND RESULTS Cytokine production and T...

Increasing evidence suggests that secondary injury after diffuse axonal injury (DAI) damages more axons than the initial insult, but the underlying mechanisms of this phenomenon are not fully understood. Recent studies show that toll-like receptor 4 (TLR4) plays a critical role in promoting adaptive immune responses and have been shown to be associated with brain damage. The purpose of this stu...
