Colitis-associated cancer (CAC) is one of the most serious complications of inflammatory bowel disease. The pathogenesis of CAC is complicated and so far elusive, and the anti-inflammatory effect does not assure CAC preventive activity, making it difficult to discover CAC preventive drugs. In this study, we report the CAC preventive effect of the ethyl acetate (EIR) of Ilex rotunda Thunb., a traditional Chinese herbal medicine being clinically used to treat intestinal disease. We also report the results of screening for CAC preventive agents from EIR via a nuclear factor-kappa B (NF-κB) translocation model in Caco2 cells, since activated NF-κB can be used by tumor cells at the early stage of tumorigenesis...

Dimethyl fumarate (DMF) is a fumaric acid ester registered for the treatment of relapsing-remitting multiple sclerosis (RRMS). It induces protein succination leading to inactivation of cysteine-rich proteins. It was first shown to possess cytoprotective and antioxidant effects in noncancer models, which appeared related to the induction of the nuclear factor erythroid 2 (NF-E2)-related factor 2 (NRF2) pathway. DMF also displays antitumor activity in several cellular and mice models. Recently, we showed that the anticancer mechanism of DMF is dose-dependent and is paradoxically related to the decrease in the nuclear translocation of NRF2...

PURPOSE: Glaucoma is a common chronic neurodegenerative disease, which could lead to visual loss. In this study, we aimed to investigate whether fisetin, a natural flavone with anti-inflammatory and antioxidant properties, is able to alleviate glaucoma. METHODS: We employed a DBA/2J mouse model which was treated with or without fisetin. Pattern electroretinogram (P-ERG), visual evoked potentials (VEPs) and intraocular pressure (IOP) were evaluated. Quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assay (ELISA) were used to measure the expression levels of TNF-α, IL-1β and IL-6...

Several rare inherited disorders have been described that show phenotypic overlap with Paget's disease of bone (PDB) and in which PDB is a component of a multisystem disorder affecting muscle and the central nervous system. These conditions are the subject of this review article. Insertion mutations within exon 1 of the TNFRSF11A gene, encoding the receptor activator of nuclear factor kappa B (RANK), cause severe PDB-like disorders including familial expansile osteolysis, early-onset familial PDB and expansile skeletal hyperphosphatasia...

Aging can be defined as the progressive failure of repair and maintenance systems with a consequent accumulation of cellular damage in nucleic acids, proteins, and lipids. These various types of damage promote aging by driving cellular senescence and apoptosis. NF-kB (nuclear factor-kappa B) pathway is one of the key mediators of aging and this pathway is activated by genotoxic, oxidative and inflammatory stress, and regulates expression of cytokines, growth factors, and genes that regulate apoptosis, cell cycle progression, and inflammation...

Thymic stromal lymphopoietin (TSLP) is a key epithelial-derived factor that aggravates allergic diseases. Therefore, TSLP inhibitors are candidate compounds for the treatment of allergic diseases. Previously, we reported that KCMH-1, a mouse keratinocyte cell line, constitutively produces TSLP. In this study, we tried to identify inhibitors of TSLP by screening 2169 compounds in KCMH-1 cells and found one such chalcone derivative (code no. 16D10). 16D10 inhibited TSLP expression and TSLP promoter activation in HaCaT cells, a human keratinocyte cell line...

White striping (WS) and woody breast (WB) are 2 of the major myopathies in the modern poultry industry. Even though the exact etiology for WS and WB is still unknown, differentially expressed genes in broiler breast muscle affected by WS and WB indicate that oxidative stress and inflammation could be involved in their occurrences. Therefore, it is very important to identify natural compounds with anti-oxidative stress and anti-inflammation properties that can reduce the occurrences of WS and WB in broiler chickens...

The receptor activator of nuclear factor kappa-B ligand (RANKL) is an important factor for osteoclastogenesis and contributes to the pathology of rheumatoid arthritis (RA); thus, the anti-RANKL antibody (Ab) has been expected to protect joint destruction in RA patients. Interleukin (IL)-8 also has osteoclastogenic activity; however, the role of IL-8 in the bone pathology of RA as well as the relation between IL-8 and RANKL remain unclear. In the present study, clinical observation revealed serum IL-8 levels of 611 pg/ml in RA patients with anti-RANKL Ab and 266 pg/ml in the same patients without anti-RANKL Ab...

Aluminum (Al) causes hippocampal lesions by oxidative stress, which is widely accepted as the primary pathogenesis of Al neurotoxicity. Lycopene (LYC), a naturally carotenoid, has received extensive attention due to its antioxidant effect. In this study, the neuroprotective effects and mechanisms of LYC against aluminum chloride (AlCl3 )-induced hippocampal lesions were explored. First, oral administration of LYC (4 mg/kg) alleviated AlCl3 -induced (150 mg/kg) cognition impairment and histopathological changes of the hippocampus in rats...

The aim of the present study was to explore whether the supercritical-carbon dioxide fluid extract from flowers and buds of Chrysanthemum indicum (SEC) exhibits antidepressant-like effects in a chronic unpredictable mild stress (CUMS)-induced mice model. Firstly, SEC was found to reverse a CUMS-induced decrease in the body weight gain in mice. Next, SEC was found to alleviate CUMS-induced depressive-like behavior, evidenced by the reversal of the decrease in the sucrose consumption in the sucrose preference test (SPT), the increase in the locomotor activity in the open field test (OPF), and the alleviation of immobility duration in both the forced swimming test (FST), and tail-suspension test (TST)...

Primary mediastinal B-cell lymphoma (PMBCL) is a distinct disease closely related to classical nodular sclerosing Hodgkin lymphoma. Conventional diagnostic paradigms utilising clinical, morphological and immunophenotypical features can be challenging due to overlapping features with other B-cell lymphomas. Reliable diagnostic and prognostic biomarkers that are applicable to the conventional diagnostic laboratory are largely lacking. Nuclear factor kappa B (NF-κB) and Janus kinase/signal transducers and activators of transcription (JAK-STAT) signalling pathways are characteristically dysregulated in PMBCL and implicated in several aspects of disease pathogenesis, and the latter pathway in host immune evasion...

BACKGROUND Diabetic retinopathy (DR) is a macrovascular complication that occurs in diabetic patients. Conventional treatments for the management of DR have many limitations. Thus, the present investigation evaluated the protective effect of fangchinoline against diabetic retinopathy (DR). MATERIAL AND METHODS DR was induced by streptozotocin (STZ; 60 mg/kg; i.p.) and rats were treated with fangchinoline 1, 3, and 10 mg/kg for 16 weeks. DR was confirmed by determining the concentration of advanced glycation end-products (AGEs) and morphology of retinal tissues...

ARPE-19 retinal pigment epithelial cells cultured in a medium containing 35 mM D-glucose led to an augmented ROS formation and release of vascular endothelial factor (VEGF)-containing exosomes compared to ARPE-19 cells cultured in a medium containing 5 mM D-glucose (standard medium). Exposing these cells to the melanocortin 5 receptor agonist (MCR5 ) PG-901 (10-10 M), for 9 d reduced ROS generation, the number of exosomes released and their VEGF content. In contrast, incubating the cells with the melanocortin receptor MCR1 agonist BMS-470539 (10-5  M) or with the mixed MCR3/4 agonist MTII (0...

Lycoris radiata (L'Her.) Herb. (L. radiata) was traditionally used as a folk medicine in China for treatment of Alzheimer's disease. However, the specific component responsible for its considerable toxicity remained unclear thus restricting its clinical trials. Narciclasine (NCS) was isolated from L. radiata and treatment of NCS for 72 h exhibited significant antiproliferative effects against L02, Hep G2, HT-29 and RAW264.7 cells. However, what needs to be emphasized is that at safe working concentrations of 0...

Zearalenone (ZEA) - a fungal mycotoxin is reported to both cause the oxidative stress associated with death of cells as well as induction of the proliferation of cells, depending on its concentration and the type of cells. ZEA due to its structural similarity to naturally occurring estrogens is able to bind to estrogen receptors and triggers estrogen-associated signaling pathways. The aim of this study is to evaluate whether the induction of oxidative stress in normal epithelial prostate PNT1A cells is associated with estrogenic activity of ZEA...

Lipopolysaccharide (LPS) administration causes immunoactivation, which negatively affects production and fertility, but experimental exposure via an acute bolus is unlikely to resemble natural infections. Thus, the objectives were to characterize effects of chronic endotoxemia on production parameters and follicular development in estrous-synchronized lactating cows. Eleven Holstein cows (169 ± 20 d in milk; 681 ± 16 kg of body weight) were acclimated to their environmental surroundings for 3 d and then enrolled in 2 experimental periods (P)...

Secondary hyperparathyroidism is a complication of chronic kidney disease that compromises skeletal integrity. In patients with secondary hyperparathyroidism undergoing parathyroidectomy, parathyroid hormone levels dramatically decrease. The effects of parathyroidectomy on bone tissue are poorly understood, especially regarding the proteins expressed by osteocytes, such as fibroblast growth factor 23, dentin matrix protein 1, matrix extracellular phosphoglycoprotein, sclerostin, receptor activator of nuclear factor kappa B ligand (RANKL) and osteoprotegerin, which regulate bone turnover...
