OBJECTIVE This study aimed to explore the expression of MALAT1 and its correlation with TNF-α production in lipopolysaccharide (LPS)-induced septic cardiomyocytes. Then, the effect of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) on LPS-induced cardiomyocyte apoptosis is further studied. MATERIALS AND METHODS The hub genes in cell response to LPS treatments was analyzed by u...

Neuro-immune mediators play an important role in the development of sickness behaviors. In the present study, the effect of captopril on sickness behaviors caused by lipopolysaccharide (LPS) was studied in the rats. The animals were randomized into the following groups: control, sham, 10 mg kg-1 captopril - LPS (Capto 10-LPS), 50 mg kg-1 captopril - LPS (Capto 50-LPS), and...

The pregnane X receptor (PXR) is a member of the nuclear receptor superfamily that regulates cytochrome P450 3A (CYP3A) gene transcription in a ligand-dependent manner. Lipopolysaccharide (LPS)-induced downregulation on PXR and cyp3a11 in adult mouse liver has been well characterized. In this study, we investigated the effects of maternal LPS exposure on PXR and cyp3a11 expression in fetal mous...

Circular RNAs (circRNAs) have been implicated in the pathology of osteoarthritis (OA). Nevertheless, precise actions circRNA protein kinase C eta (circ-PRKCH, hsa_circ_0032131) on OA pathogenesis are still undiscovered. Cell viability and apoptosis were determined using Counting-8 Kit (CCK-8) assay flow cytometry, respectively. The levels circ-PRKCH, microRNA (miR)-140- 3p a-disintegrin metallo...

Objective: Neuroimmune factors contribute on the pathogenesis of sickness behaviors. Nigella sativa (NS) has anti-inflammatory, anti-anxiety and anti-depressive effects. In the present study, the effect of NS hydro-alcoholic extract on sickness behavior induced by lipopolysaccharide (LPS) was investigated. Materials and Methods: The rats were divided into five groups (n=10 in each): (1) control...

INTRODUCTION The pathophysiology of endotoxemia-induced acute kidney injury (AKI) is characterized by an intense activation of the host immune system and renal resident cells by lipopolysaccharide (LPS) and derived proinflammatory products. However, the occurrence of renal fibrosis in this setting has been poorly investigated. The aim of the present study was to investigate the possible associa...

Abstract Objective To investigate lncRNAs and their roles in regulating the pulmonary inflammatory response under dexamethasone (Dex) treatment. Methods IL-1? (10 ng/mL) LPS (1 ?g/mL) was used to construct cell models with A549 cells; performed better against LPS. Different concentrations of Dex were attenuate inflammation induced by IL-1?, its effect assessed via RT-PCR detect cytokine-related...

Cholestasis is frequently related to endotoxemia and inflammatory response. Our previous investigation revealed a significant increase in plasma endotoxin and CD14 levels during biliary atresia. We therefore propose that lipopolysacharides (LPS) may stimulate CD14 production in liver cells and promote the removal of endotoxins. The aims of this study are to test the hypothesis that CD14 is upre...

The inflammatory endothelial response to LPS is critical to the host's surviving a gram-negative bacterial infection. In this study we investigated whether human endothelial cells express the functional coreceptor for LPS, CD14, and most importantly whether it is glycosylphosphatidylinositol (GPI) linked. We also examined whether plasma proteins could reconstitute an LPS response in CD14-inhibi...

Introduction Neutrophils have been involved in sepsis-induced organ damage. Neutrophils could be directly activated by TLR binding ligands including LPS. IRAK-1 is one of many intracellular proteins that are activated upon stimulation of TL receptors. This triggers a series of events that results in the migration of NF-κB into the nucleus and the activation NF-κB-dependent genes. Objectives To ...
