Tumour necrosis factor-α (TNFα) is a multifarious mediator of lymphoid tissue growth and antimicrobial defence mechanisms, it acts as pro-inflammatory regulator. The function TNFα in parasite infection the underlying mechanism through which nuclear factor-κB (NF-κB) regulates remain largely unclear teleosts. In present study, ( ToTNF α) from golden pompano Trachinotus ovatus ) was identified, i...

The roles of myocardin-related transcription factor A (MRTF-A) and MRTF-B in vascular endothelial cells are not completely understood. Here, we found a novel regulatory mechanism for MRTF-A/B function. MRTF-A/B tend to accumulate in the nucleus in arterial endothelial cells in vivo and human aortic endothelial cells (HAoECs) in vitro. In HAoECs, nuclear localization of MRTF-A/B was not signific...

The transcription factor nuclear factor-κB (NF-κB) exerts essential roles in many biological processes including cell growth, apoptosis and innate and adaptive immunity. The NF-κB inhibitor (IκBα) retains NF-κB in the cytoplasm and thus inhibits nuclear localization of NF-κB and its association with DNA. Recent protein crystal structures of the C-terminal part of IκBα in complex with NF-κB prov...

Osteoclasts are multinucleated cells formed mainly on bone surfaces in response to cytokines by fusion of bone marrow-derived myeloid lineage precursors that circulate in the blood. Major advances in understanding of the molecular mechanisms regulating osteoclast formation and functions have been made in the past 20 years since the discovery that their formation requires nuclear factor-κB (NF-κ...

BACKGROUND Acute kidney injury (AKI) is a major risk factor for the development of chronic kidney disease. Nuclear factor-κB is a nuclear transcription factor activated post-ischemia, responsible for the transcription of proinflammatory proteins. The role of nuclear factor-κB in the renal fibrosis post-AKI is unknown. METHODS AND RESULTS We used a rat model of AKI caused by unilateral nephrec...

Nuclear factor κB (NF-κB) is a key factor in the development of chronic inflammation and is deeply involved in age-related and metabolic diseases development. These diseases have become a serious problem in cats. Sirtuin 1 (SIRT1) is associated with aging and metabolism through maintaining inflammation via NF-κB. In addition, fibroblasts are considered an important factor in the development of ...

Objectives: Epithelial-mesenchymal transition (EMT) of renal tubular epithelial cells (RTECs) is a pathogenic factor for interstitial fibrosis (RIF). Interleukin-33 (IL-33) related to the occurrence and development RIF, but underlying mechanism remains unclear. Here, we investigated whether IL-33 mediates EMT RTECs by activating NF-κB/Twist1 signalling pathway. Methods: In vivo, RIF animal mode...

Nuclear factor κB (NF-κB) is a transcription factor that regulates various aspects of immune response, cell death, and differentiation as well as cancer. In this study we introduce the Py-Im polyamide 1 that binds preferentially to the sequences 5'-WGGWWW-3' and 5'GGGWWW-3'. The compound is capable of binding to κB sites and reducing the expression of various NF-κB-driven genes including IL6 an...

Oncogenic proteins cooperate to promote tumor development and progression by sustaining cell proliferation, survival and invasiveness. Constitutive epidermal growth factor receptor (EGFR) and nuclear factor κb (NF-κB) activities are seen in multiple solid tumors and combine to provide oncogenic signals to cancer cells. Understanding how these oncogenic pathways are connected is crucial, given t...
