To evaluate the expression of miR-155 and autophagy in COPD related mechanism. Alveolar macrophages were extracted from patients. dynamic mouse model was established. Mouse alveolar also isolated cultured. Rat macrophage cell line NR8383 introduced. The TLR4 NF-κB cells with CSE treatment evaluated. upregulated bronchoalveolar lavage fluid patients, treated (p < 0.05). Overexpression miR‐155 le...

The Nuclear factor-2 erythroid related factor-2 (Nrf2) is a redox regulated transcription factor involved in the regulation of antioxidant defence systems. It drives the production of endogenous antioxidant defences and detoxifying enzymes. Nuclear factor-kappa light chain enhancer of B cells (NF-κB) is a transcription factor, involved in proinflammatory cytokine production, in addition to its ...

Abstract Background Necrotizing enterocolitis (NEC) remains a fatal gastrointestinal disorder in neonates and has very limited therapeutic options. Sialylated human milk oligosaccharides (SHMOs) improve pathological changes experimental NEC models. The objectives of this study were to investigate the involvement NLRP3 inflammasome pathology explore effects SHMOs on toll-like receptor 4 (TLR4)/n...

Background and Aim. Daphnetin, an active monomer ingredient extracted from D. marginata, is proved to have anti-inflammatory antioxidant effect. The aim of this study explore the effect possible mechanism daphnetin on acute lung injury (ALI) associated with pancreatitis (AP) in mice. Methods. A total 36 mice were randomly assigned into three groups: control group, AP group. mouse model was indu...

OBJECTIVE We studied the involvement of the TLR4/NF-κB pathway in the growth of colon cancer using human colon cancer specimens, human colon cancer SW620 cell line, and nude mouse xenograft model. MATERIALS AND METHODS Tissue samples were surgically harvested. The human colon cancer SW620 cell line was pre-treated with the TLR4 inhibitor CRX-526 and stimulated with LPS. The nude mouse xenogra...

Radiation-induced intestinal injuries (RIII) commonly occur in patients who suffer from pelvic or abdominal cancer. Nuclear factor-erythroid 2-related factor 2 (Nrf2) is a key transcriptional regulator of antioxidant, and the radioprotective role of Nrf2 is found in bone marrow, lung, and intestine, etc. Here, we investigated the effect of Nrf2 knockout on radiation-induced intestinal injuries ...

Sepsis syndrome is characterized by a dysregulated inflammatory response to infection. NADPH oxidase-dependent reactive oxygen species (ROS) play significant roles in the pathophysiology of sepsis. We previously showed that disruption of Nrf2, a master regulator of antioxidant defenses, caused a dysregulation of innate immune response that resulted in greater mortality in a polymicrobial sepsis...

Objectives. The effects of Kluyveromyces marxianus on high-fat diet- (HFD-) induced kidney injury (KI) were explored. Methods. HFD-induced KI model was established using male C57BL/6 mice and treated with K. JLU-1016 acid-resistant (AR) strain JLU-1016A. Glucose tolerance evaluated via an oral glucose test (OGTT). measured Hematoxylin Eosin (H&amp;E) staining terminal deoxynucleotidyl transfera...

Suppressor of cytokine signaling 2 (SOCS2) was reported to be involved in the development of Diabetic Nephropathy (DN). However, its underlying mechanism remains undefined. Western blot was carried out to determine the expressions of SOCS2, Toll-like receptors 4 (TLR4) and nuclear factor kappa B (NF-κB) pathway-related proteins in DN patients, streptozotocin (STZ)-induced DN rats and high gluco...

OBJECTIVES The alteration of the Toll-like receptor/nuclear factor-kappa B (TLR4/NF-κB) signaling pathway during deep hypothermia circulatory arrest (DHCA) has not yet been defined. The aim of this study was to explore the expression of the TLR4/NF-κB pathway cytokine in cerebral injury resulting from DHCA as well as the effect of selective antegrade cerebral perfusion (SACP) on TLR4/NF-κB path...
