The aim of this study was to investigate the role of inducible nitric oxide synthase (iNOS) in gentamicin-induced acute tubular necrosis in rats using the iNOS inhibitor L-N6-(1-iminoethyl) lysine (L-NIL). Wistar rats, both sexes (n=18), were equally divided into three groups. Gentamicin group
Dietary and plasma carboxymethyl lysine (dCML, pCML) and plasma tumor necrosis factor-α (pTNF-α) may be associated with obesity in affluent society. However, evidence in women from low-middle income countries with predominantly traditional diets is lacking. We investigated the mediator effects of
Ubiquitination-mediated degradation of the RelA subunit of nuclear factor-kappaB (NF-kappaB) is critical for the termination of NF-kappaB activation. However, the precise mechanism for the ubiquitination of RelA is still not fully understood. Here we report that tumor necrosis factor-alpha
We have recently shown that interferon regulatory factor 7 (IRF7) is activated by Epstein-Barr virus latent membrane protein 1 (LMP1), a member of the tumor necrosis factor receptor (TNFR) superfamily, through receptor-interacting protein-dependent K63-linked ubiquitination (L. E. Huye, S. Ning, M.
NH2-terminal glycine myristyl acylation is a cotranslational modification that affects both protein localization and function. However, several proteins that lack NH2-terminal glycine residues, including the interleukin 1 (IL-1) precursors, also contain covalently linked myristate. To date, the
Periodontitis is a chronic inflammatory disease accompanied by alveolar bone resorption by osteoclasts. Porphyromonas gingivalis, an etiological agent for periodontitis, produces cysteine proteases called gingipains, which are classified based on their cleavage site specificity (i.e. arginine (Rgps)
Background and purpose: Neuroinflammation has been proven to play an important role in the pathogenesis of early brain injury after subarachnoid hemorrhage (SAH). EZH2 (enhancer of zeste homolog 2)-mediated H3K27Me3 (trimethylation of
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has been characterized as an anti-cancer therapeutic agent with prominent cancer cell selectivity over normal cells. However, breast cancer cells are generally resistant to TRAIL, thus limiting its therapeutic potential. In this study,
Transforming growth factor-beta-activated kinase 1 (TAK1) plays an essential role in the tumor necrosis factor alpha (TNFalpha)- and interleukin-1beta (IL-1beta)-induced IkappaB kinase (IKK)/nuclear factor-kappaB (NF-kappaB) and c-Jun N-terminal kinase (JNK)/activator protein 1 (AP-1) activation.
Purpose: Regulation of gene expression is fine-tuned by a dynamic equilibrium between repressive modifications and transcriptional activation of histone tails. Jumonji domain-containing 3 (Jmjd3), also known as KDM6B, is a specific histone demethylase for trimethylation on histone H3 lysine
Calcium-sensing receptor (CaSR) is involved in maintaining cellular homeostasis and promoting recovery of damaged intestinal epithelial cells (IECs). Poly-L-lysine (PL) is a basic polypeptide identified for its role in the activation of CaSR through allosteric binding. The primary goal of the
Reactive oxygen species are suggested to participate in ischemia-reperfusion (I-R) injury. However, induction of inducible nitric oxide synthase (iNOS) and production of high levels of nitric oxide (NO) also contribute to this injury. NO can combine with superoxide to form the potent oxidant
Background: Parkinson's disease (PD) is a neurodegenerative disease characterized by intracellular inclusions named Lewy bodies (LB), and alpha-synuclein (asyn) is the major component of these protein aggregates. The precise physiological
Human and murine monocyte-macrophages kill actinomycin D (ActD)-treated WEHI 164 sarcoma cells in a 6-hr 51Cr-release assay (drug-dependent cellular cytotoxicity, DDCC). In this study, we have investigated the cytotoxic activity of human recombinant tumour necrosis factor (hrTNF) against untreated
Nε-(carboxymethyl)lysine (CML), which is a compound produced when food is processed, has aroused concern in recent years because of its potentially dangerous effects. This study aimed to investigate the mechanism of free CML-induced toxic injury in mice. The inflammatory cytokine tumor necrosis
