The nuclear factor κB (NF-κB) signalling pathway controls important cellular events such as cell proliferation, differentiation, apoptosis and immune responses. Pathway activation occurs rapidly upon TNFα stimulation and is highly dependent on ubiquitination events. Using cytoplasmic to nuclear translocation of the NF-κB transcription factor family member p65 as a read-out, we screened a synthe...
Downregulation of TRAF2 Mediates NIK-Induced Pancreatic Cancer Cell Proliferation and Tumorigenicity
BACKGROUND Increased levels of NF-κB are hallmarks of pancreatic ductal adenocarcinoma (PDAC) and both classical and alternative NF-κB activation pathways have been implicated. METHODOLOGY/PRINCIPAL FINDINGS Here we show that activation of the alternative pathway is a source for the high basal NF-κB activity in PDAC cell lines. Increased activity of the p52/RelB NF-κB complex is mediated thro...
Tolerance to bacterial components represents an essential regulatory mechanism during bacterial infection. Bacterial lipoprotein (BLP)-induced tolerance confers protection against microbial sepsis by attenuating inflammatory responses and augmenting antimicrobial activity in innate phagocytes. It has been well-documented that BLP tolerance-attenuated proinflammatory cytokine production is assoc...
Nuclear factor- κB (NF- κB) plays a pivotal role in the regulation of immune and inflammatory responses. The real-time expression level of NF- κB reflects the development of ulcerative colitis (UC). Polydatin has vast pharmacological activities, including inhibiting the production of inflammatory mediators, inducing the production of antioxidants, regulating immune function, etc. The purpose of...
The present study examined the effects of simvastatin on the proliferation, apoptosis and gene expression levels involved in the nuclear factor-κB (NF-κB) signaling pathway in the human acute promyelocytic leukemia NB4 cell line by methyl thiazolyl tetrazolium assay, flow cytometry and the Human NF-κB Signaling Pathway RT2 Profiler™ PCR Array profiles. The results showed that simvastatin signif...
The transcription factor NF-κB (nuclear factor κB) regulates critical cellular processes including the inflammatory response, apoptosis and the cell cycle. Over the past 20 years many of the components of the NF-κB signalling pathway have been elucidated along with their functions. Recent research in this field has focused on the dynamic regulation and network control of this system. With key r...
BACKGROUND Tumor necrosis factor-α and other proinflammatory cytokines activate the canonical nuclear factor (NF)-κB pathway through the kinase IKKβ. Previously, we established that IKKβ is also critical for Akt-mediated NF-κB activation in ventricular myocytes. Akt activates the kinase mammalian target of rapamycin (mTOR), which mediates important processes such as cardiac hypertrophy. However...
BACKGROUND/AIM We have demonstrated that exogenous hydrogen sulfide (H2S) protects H9c2 cardiac cells against the doxorubicin (DOX)-induced injuries by inhibiting p38 mitogen-activated protein kinase (MAPK) pathway and that the p38 MAPK/nuclear factor-κB (NF-κB) pathway is involved in the DOX-induced inflammatory response and cytotoxicity. The present study attempts to test the hypothesis that ...
Intracellular replication of Salmonella enterica requires effector proteins translocated across the Salmonella-containing vacuolar membrane by Salmonella pathogenicity island-2 (SPI-2) encoded type III secretion system (T3SS). The SPI-2 T3SS effector SseL is a deubiquitinase that contributes to virulence in mice. Previous work has produced conflicting evidence as to the involvement of SseL in i...
We present the first comparison of global transcriptional changes in canine and human diffuse large B-cell lymphoma (DLBCL), with particular reference to the nuclear factor-kappa B (NF-κB) pathway. Microarray data generated from canine DLBCL and normal lymph nodes were used for differential expression, co-expression and pathway analyses, and compared with analysis of microarray data from human ...
