BACKGROUND NF-κB inhibits apoptosis through induction of antiapoptotic proteins and suppression of proapoptotic genes. Various chemotherapy agents induce NF-κB translocation and target gene activation. We conducted the present study to assess the predictive value of NF-κB regarding pathologic responses after receiving neoadjuvant chemotherapy. MATERIALS AND METHODS We enrolled 131 patients wi...

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 kappa B (NF-κB) regulates genes that function in diverse cellular processes like inflammation, immunity and cell survival. The activation of NF-κB is tightly controlled and the deubiquitinase CYLD has emerged as a key negative regulator of NF-κB signalling. Optineurin, mutated in certain glaucomas and amyotrophic lateral sclerosis, is also a negative regulator of NF-κB activa...

While inflammation with aberrant activation of NF-κB pathway is a hallmark of cystic fibrosis (CF), the molecular mechanisms underlying the link between CFTR defect and activation of NF-κB-mediated pro-inflammatory response remain elusive. Here, we investigated the link between CFTR defect and NF-κB activation in ΔF508cftr-/- mouse intestine and human intestinal epithelial cell lines. Our resul...

Susceptibility to mastitis is highest during the peripartal (transition) period and often concomitant with other comorbidities such as ketosis. Although infection pathogenic microorganisms immune-dysfunction around calving clearly play key roles in development, metabolic factors also contribute. Sirtuin 3 (SIRT3), a mitochondrial deacetylase regulating energy redox homeostasis, antagonizes lipo...

Both the canonical and noncanonical nuclear factor κB (NF-κB) pathways have been linked to tumorigenesis. However, it remains unknown whether and how the 2 signaling pathways cooperate during tumorigenesis. We report that inhibition of the noncanonical NF-κB pathway significantly delays tumorigenesis mediated by the viral oncoprotein Tax. One function of noncanonical NF-κB activation was to rep...

NF-κB is a ubiquitously expressed transcription factor that regulates a large number of genes in response to diverse physiological and pathological stimuli. The regulation of the transcriptional activity of NF-κB is often dependent on its interaction with IκBα. Proteins that bind to IκBα are critical regulators of NF-κB activity. DDRGK1 is a member of the DDRGK domain-containing protein family ...

Promyelocytic Leukemia (PML) is a nuclear protein that forms sub-nuclear structures termed nuclear bodies associated with transcriptionally active genomic regions. PML is a tumour suppressor and regulator of cell differentiation. We demonstrate that PML promotes TNFα-induced transcriptional responses by promoting NF-κB activity. TNFα-treated PML-/- cells show normal IκBα degradation and NF-κB n...

The transcription factor NF-κB (p65/p50) plays a central role in the coordination of cellular responses by activating the transcription of numerous target genes. The precise role of the dynamics of NF-κB signalling in regulating gene expression is still an open question. Here, we show that besides external stimulation intracellular parameters can influence the dynamics of NF-κB. By applying mat...

Besides myelination of neuronal axons by oligodendrocytes to facilitate propagation of action potentials, oligodendrocytes also support axon survival and function. A key transcription factor involved in these processes is nuclear factor-κB (NF-κB), a hetero or homodimer of the Rel family of proteins, including p65, c-Rel, RelB, p50, and p52. Under unstimulated, NF-κB remains inactive in the cyt...
