signaling amp-activated protein kinase (ampk), an energy sensing enzyme, has been implicated in controlling inflammation. in this study we investigated whether activation of ampk by metformin could protect the lung from lipopolysaccharide (lps)-induced acute injury by inhibitingng tlr4 pathway. male wistar rats were randomly divided into 3 groups (n=6): control group received normal saline (0.5...
Abstract Lipid nanoparticles (LNP) are essential components of messenger RNA (mRNA) vaccines that have been a cornerstone the COVID-19 public health response. These LNPs used for cell entry and protection mRNA. Others shown LNP BNT162b2 vaccine is able to augment immune response against target. However, it unknown how this stimulates innate cells such as monocytes participate in engagement adap...
The nuclear factor κB (NF-κΒ) subunits RelA, RelB, cRel, p50, and p52 are each critical for B cell development and function. To systematically characterize their responses to canonical and noncanonical NF-κB pathway activity, we performed chromatin immunoprecipitation followed by high-throughput DNA sequencing (ChIP-seq) analysis in lymphoblastoid B cell lines (LCLs). We found a complex NF-κB-b...
Activation of the nuclear factor κB (NF-κB) signaling pathway may be associated with the development of cardiac hypertrophy and transition to heart failure (HF). The transgenic mouse, MyoTg, develops hypertrophy and HF as a result of overexpression of myotrophin in the heart associated with elevated level of NF-κB activity. Using this mouse model and an NF-κB-targeted gene array, we first deter...
Nuclear factor (NF)-κB has evolved as a latent, inducible family of transcription factors fundamental in the control of the inflammatory response. The transcription of hundreds of genes involved in inflammation and immune homeostasis require NF-κB, necessitating the need for its strict control. The inducible ubiquitination and proteasomal degradation of the cytoplasmic inhibitor of κB (IκB) pro...
The human T-lymphotropic virus type I (HTLV-I) causes a chronic inflammatory disorder of the central nervous system termed HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP). HTLV-I encodes a protein known to activate several host-signaling pathways involved in inflammation, such as the nuclear factor-κB (NF-κB). The contribution of the NF-κB pathway to the pathogenesis of HAM/...
Generally, both lipopolysaccharide (LPS)- and hypoxia-induced nuclear factor kappa B (NF-κB) effects are alleviated through differential posttranslational modification of NF-κB phosphorylation after pretreatment with 5´-AMP-activated protein kinase (AMPK) activators such as 5´-aminoimidazole-4-carboxamide ribonucleotide (AICAR) or the hypoglycemic agent metformin. We found that AICAR or metform...
NF-κB is a family of important transcription factors that modulate immunity, development, inflammation, and cancer. The biological activity of NF-κB is subjected to various spatial and temporal regulations. Bioinformatics analysis predicts that CITED2 is topologically close to NF-κB in the protein interaction networks. In this study, we show that ectopic expression or knockdown of CITED2 attenu...
The NF-κB pathway transcriptionally controls a large set of target genes that play important roles in cell survival, inflammation, and immune responses. While many studies showed anti-tumorigenic and pro-survival role of NF-κB in cancer cells, recent findings postulate that NF-κB participates in a senescence-associated cytokine response, thereby suggesting a tumor restraining role of NF-κB. In ...
NF-κB is a major transcriptional factor regulating many cellular functions including inflammation; therefore, its appropriate control is of high importance. The detailed mechanism of its activation has been well characterized, but that of negative regulation is poorly understood. In this study, we showed AMAP1, an Arf-GTPase activating protein, as a negative feedback regulator for NF-κB by bind...
