Purpose: Aberrant expression and dysfunction of RSF1 has been reported in diverse human malignancies. However, its exact role in nasopharyngeal carcinoma (NPC) remains unclear. Methods: The expression of RSF1 mRNA and protein were assayed by qRT-PCR and western blotting, and their correlations with clinicopathological parameters of patients with NPC were further analysed. Lentivirus mediated RS...

BACKGROUND Monocyte chemoattractant protein-1 (MCP-1) plays an important role in extracellular matrix accumulation through macrophage recruitment and activation in the development and progression of diabetic nephropathy. Therefore, this study examined whether advanced oxidation protein products (AOPPs) are involved in nuclear factor-κB (NF-κB) activation and MCP-1 mRNA and protein expression in...

Purpose: To investigate the role of RAS-like protein A (RalA) in lipopolysaccharide-induced inflammatory regulation primary microglia chronic constriction injury (CCI)-induced neuropathic pain rat models.
 Methods: In vitro, overexpression (OE) RalA was performed using transfection procedure, and then LPS used to provoke phenotype. vivo, model induced CCI treated with LV-RalA. Neuroinflamm...

HOX proteins define a family of key transcription factors regulating animal embryogenesis. HOX genes have also been linked to oncogenesis and HOXA1 has been described to be active in several cancers, including breast cancer. Through a proteome-wide interaction screening, we previously identified the TNFR-associated proteins RBCK1/HOIL-1 and TRAF2 as HOXA1 interactors suggesting that HOXA1 is fu...

Objective Fuyuan Huoxue decoction (FHD) is a traditional Chinese medicine that can promote blood circulation, inhibit inflammatory reactions and effectively relieve pain. This study investigated the effect of FHD on rat skin flap survival p38 MAPK/IKK/NF-κB pathway. Methods The pathological condition tissue was examined by H&E staining. expression levels CD34 VEGF in tissues were immunohist...

Nuclear factor kappa B (NF-κB) and type 1 interferon (T1-IFN) signaling are innate immune mechanisms activated upon viral infection. However, the role of NF-κB and its interplay with T1-IFN in antiviral immunity is poorly understood. We show that NF-κB is essential for resistance to ectromelia virus (ECTV), a mouse orthopoxvirus related to the virus causing human smallpox. Additionally, an ECTV...

BACKGROUND During pathogen infection, innate immunity is initiated via the recognition of microbial products by pattern recognition receptors and the subsequent activation of transcription factors that upregulate proinflammatory genes. By controlling the expression of cytokines, chemokines, anti-bacterial peptides and adhesion molecules, the transcription factor nuclear factor-kappa B (NF-κB) h...

Although it has been known for a long time that ubiquitylation has a major role in the activation and regulation of the nuclear factor kappa B (NF-κB) pathway, recent studies have revealed that the picture is a lot more complex than originally thought. NF-κB and ubiquitylation initially became linked when it was recognised that lysine (K)48-linked ubiquitin chains are involved in the processing...

Endothelial barrier disruption is a hallmark of multiple organ injury (MOI). However, mechanisms governing the restoration of endothelial barrier function are poorly understood. Here, we uncovered an NF-κB-to-AP-1 switch that regulates the transition from barrier injury to repair following endotoxemic MOI. Endothelial NF-κB mediates barrier repair by inhibiting endothelial cell (EC) apoptosis. ...

Metastatic squamous cell carcinoma of the head and neck (SCCHN) has been shown to express chemokine receptor 7 (CCR7), which activates phosphoinositide-3 kinase/Akt/mammalian target of rapamycin (PI3K/Akt/mTOR) signal pathway to promote the invasion and survival of SCCHN cells. Since nuclear factor-kappa B (NF-κB) is shown to be the downstream signal molecule of PI3K/Akt in many tumors, we inve...
