The characteristic hemorrhages of acute promyelocytic leukemia (APL) are caused in part by the high expression of tissue factor (TF) on leukemic cells, which also produce TNF and IL-1β, proinflammatory cytokines known to increase TF in various cell types. Exposure of NB4 cells, an APL cell line, to all-trans retinoic acid (ATRA) or arsenic trioxide (ATO) rapidly and strongly reduced TF mRNA. Both drugs also reduced TNF mRNA, but later, and moreover increased IL-1β mRNA. The effect on procoagulant activity of cells and microparticles, as measured with calibrated automated thrombography, was delayed and only partial at 24 h...

Changes in plasma concentration of small organic metabolites could be due to their altered production or urinary excretion and changes in their urine concentration may be due to the changes in their filtered load, tubular reabsorption, and/or altered urine volume. Therefore, these factors should be considered in interpretation of the changes observed in plasma or urine of the target metabolite(s). Fasting plasma and urine samples from 180 CKD patients and 120 age-matched healthy controls were determined by UPLC-HDMS-metabolomics and quantitative real-time RT-PCR techniques...

Cartilage endplate (CEP) cell calcification and apoptosis play a vital role in the intervertebral disc degeneration (IVDD). Oxidative stress is a key factor in inducing programmed cell death and cartilage calcification. However, the cell death and calcification of cartilage endplate cells under oxidative stress have never been described. The present study investigated the apoptosis and calcification in the cartilage endplate cell under oxidative stress induced by H2O2 to understand the underlying mechanism of IVDD...

Multiple sclerosis (MS) is an immune-mediated demyelinating disease of the central nervous system, and its pathogenesis remains largely unclear. Much attention has been paid to the role of microRNAs (miRs) in regulation of autoimmune disease. Here, we found, for the first time, that miR-448 expression was significantly increased in periphery blood mononuclear cells (PBMC) and cerebrospinal fluid (CSF) of patients with MS, and its expression positively correlated with the disease severity. We further demonstrated that CD4(+) T cells, especially the Th17 lineage, were the major source of miR-448 expression...

Autoimmune disorders are distinct with over production and accumulation of free radicals due to its undisclosed genesis. The cause of numerous disorders as cancer, arthritis, psoriasis, diabetes, alzheimer's, cardiovascular disease, Parkinson's, respiratory distress syndrome, colitis, crohn's, pulmonary fibrosis, obesity and ageing have been associated with immune dysfunction and oxidative stress. In an oxidative stress, reactive oxygen species generally provoke the series of oxidation at cellular level. The buildup of free radicals in turn triggers various inflammatory cells causing release of various inflammatory interleukins, cytokines, chemokines, and tumor necrosis factors which mediate signal transduction and transcription pathways as nuclear factor- kappa B (NF-κB), signal transducer and activator of transcription 3 (STAT3), hypoxia-inducible factor-1 (HIF-1α) and nuclear factor-erythroid 2-related factor (Nrf2)...

The double-stranded RNA-dependent kinase (PKR), which is activated by double stranded RNA, induces inflammation by regulating NF-κB signaling. The NLR family pyrin domain-containing 3 (NLRP3) inflammasome also modulates inflammation in response to infection. Porphyromonas gingivalis (P.gingivalis) is an oral bacterium which is implicated in the pathogenesis of periodontal diseases. We previously reported that PKR is a key modulator of bone metabolism and inflammation in the periodontal tissue. PKR was also reported to induce inflammation in response to microbes by regulating the NLRP3 inflammasome, suggesting that PKR could affect inflammation along with NLRP3 in periodontal diseases...

Porcine parvovirus (PPV) is a pathogenic factor that primarily induces severe reproductive failure of pregnant swine, which results in extensive losses to the swine industry worldwide. In this study, a potential mechanism of PPV-induced activation of the nuclear transcription factor-kappaB (NF-κB) by infection in porcine kidney cells (PK-15) was elucidated for the first time. The subcellular localization of p65 analyzed by immunofluorescence assay (IFA) showed that PPV infection induced p65 translocation from the cytoplasm to the nucleus...

PURPOSE: Lung ischemia-reperfusion injury (LIRI) can complicate lung transplantation or cardiac surgery with cardiopulmonary bypass, increasing morbidity and mortality. In LIRI, pro-inflammatory cytokines are activated, reactive oxygen species are generated and nuclear factor-κB (NF-κB) is up-regulated, altering lung mechanics. We tested the effect of the flavonoid apigenin on a rodent model of LIRI. METHODS: Thirty-seven Wistar rats were subjected to LIRI with or without a single or double dose of apigenin...

The proinflammatory factor high‑mobility group box protein 1 (HMGB1) has been implicated in the pathogenesis of lung fibrosis; however, the role of HMGB1 in lung fibrosis remains unclear. It has previously been reported that nuclear factor (NF)‑κB and transforming growth factor (TGF)‑β1 may be involved in lung fibrosis. Therefore, the present study aimed to examine the potential molecular mechanisms that underlie HMGB1‑induced lung fibrosis via the regulation of NF‑κB and TGF‑β1. The results demonstrated that HMGB1 stimulation increased the activation of NF‑κB and the release of TGF‑β1, as well as the expression of α‑smooth muscle actin (α‑SMA) and collagen I in human lung fibroblasts in vitro...

Activation of C-C chemokine receptor type 7 (CCR7) has been demonstrated to mediate the occurrence and progression of non-small cell lung cancer (NSCLC). However, the potential therapeutic role of CCR7 inhibition in NSCLC is still obscure. Thus, the present study was conducted to investigate the molecular mechanism underlying the inhibition of CCR7 on cell apoptosis and epithelial-mesenchymal transition (EMT) in NSCLC A549 cells. Chemokine ligand 21 (CCL21) was used to activate CCR7 and the results revealed that CCR7 upregulation inhibited cell apoptosis and affected apoptosis‑related protein levels...

Epstein-Barr virus (EBV) infection is closely related to carcinogenesis of various cancers, and is also associated with the development of drug resistance in cancer stem cells. However, in EBV-positive cancer cells, the mechanistic details of the downstream signaling and the connection of PI3K with the NF-κB pathway for development of drug resistance remain controversial. Diffuse large B-cell lymphoma (DLBCL) and multiple myeloma (MM) cells infected by EBV display drug resistance-related proteins (MDR1, MRP1 and MRP2) and stem cell markers (OCT4 and SOX2)...

Concentrated leukocytes in leukocyte and platelet‑rich plasma (L‑PRP) may deliver increased levels of pro‑inflammatory cytokines to activate the nuclear factor (NF)‑κB signaling pathway, to counter or overwhelm the beneficial effects of growth factors on cartilage regeneration. However, to date, no relevant studies have substantiated this. In the present study, L‑PRP and pure platelet‑rich plasma (P‑PRP) were prepared, and leukocytes, platelets, pro‑inflammatory cytokines and growth factor concentrations were quantified; they were then used to treat human articular chondrocytes (HACs)...

Breast cancer metastasis suppressor 1 (BRMS1) can specifically regulate tumor metastasis in many cancers. Our previous studies have demonstrated that BRMS1 can promote cell apoptosis through regulating osteopontin (OPN) expression in hepatocellular carcinoma (HCC) cells. However, the transcriptional targets of BRMS1 have not been thoroughly studied. In this study, death-associated protein kinase 1 (DAPK1), a tumor suppressor gene with multiple roles in regulating cell death, was identified as a potential transcriptional target of BRMS1 in the whole genome expression microarray...
