Moringa (Moringa oleifera Lam.) seed extract (MSE) has anti-inflammatory and antioxidant activities. We investigated the effects of MSE enriched in moringa isothiocyanate-1 (MIC-1), its putative bioactive, on ulcerative colitis (UC) and its anti-inflammatory/antioxidant mechanism likely mediated through Nrf2-signaling pathway. Dextran sulfate sodium (DSS)-induced acute (n = 8/group; 3% DSS for 5 d) and chronic (n = 6/group; cyclic rotations of 2.5% DSS/water for 30 d) UC was induced in mice that were assigned to 4 experimental groups: healthy control (water/vehicle), disease control (DSS/vehicle), MSE treatment (DSS/MSE), or 5-aminosalicyic acid (5-ASA) treatment (positive control; DSS/5-ASA)...

The formation of atherosclerosis is recognized to be caused by multiple factors including pathogenesis in monocytes during inflammation. The current study provided evidence that monocytic junctions were significantly altered in patients with atherosclerosis, which suggested an association between cell junctions and atherosclerosis. Claudin‑1, occludin‑1 and ZO‑1 were significantly enhanced in atherosclerosis, indicating that the tight junction pathway was activated during the pathogenesis of atherosclerosis...

PURPOSE: Cell lines are extremely useful tools in breast cancer research. Their key benefits include a high degree of control over experimental variables and reproducibility. However, the advantages must be balanced against the limitations of modelling such a complex disease in vitro. Informed selection of cell line(s) for a given experiment now requires essential knowledge about molecular and phenotypic context in the culture dish. METHODS: We performed multidimensional profiling of 36 widely used breast cancer cell lines that were cultured under standardised conditions...

Malignant cancers are distinguished from more benign forms of cancers by enhanced ability to disseminate. A number of factors aid the migration and invasion of malignant cancer cells. Epithelial-to-mesenchymal transition (EMT), which greatly facilitates the dissemination of cancer cells, is characterized by the loss of epithelial markers and the acquisition of mesenchymal markers thereby rendering the cells more migratory and invasive. We have previously shown that the class III lysine deacetylase SIRT1 plays a critical role curbing the metastasis of ovarian cancer cells partly by blocking EMT...

Tetracyclines are frequently used in food-producing animals to treat, control, and prevent microbial diseases. Concerns are raised regarding the effects of residual levels of tetracycline, which may be present in the food supply, for emergence of drug-resistance and transfer of antibiotic-resistance gene in intestinal microbiota. In contrast, no information is available regarding the possible effects of residual tetracycline on the gastrointestinal epithelial layer barrier-disruption. This study investigates the outcome of tetracycline treatment on intestinal epithelial cells integrity...

The loss of salivary gland function caused by radiation therapy of the head and neck is a serious condition and it affects a patient's quality of life. The current lack of effective therapies demands new options to be explored. This study tested whether human salivary gland epithelial cells (SGECs) could be successfully cultured on a decellularized porcine gut matrix (SIS-muc) in both mono- and coculture with microvascular endothelial cells (mvECs). By performing immunofluorescence imaging, transmission as well as scanning electron microscopy (SEM), quantitative polymerase chain reaction (qPCR), and an amylase enzyme assay, it was investigated as to what extent the three-dimensional (3D)-cultured cells could maintain their molecular differentiation and the production of working α-amylase (α-AMY) compared with two-dimensional (2D) culture...

Purpose: Proinflammatory cytokines such as tumor necrosis factor (TNFα) may have a causative role in blood-retinal barrier (BRB) disruption, which is an essential step in the development of diabetic macular edema. The purpose of our study was to determine whether TNFα increases permeability in an in vitro model of the BRB and to explore the mechanisms involved. Methods: Primary bovine retinal endothelial cells (BRECs) were grown on Transwell inserts and cells were stimulated with TNFα or a combination of TNFα, IL1β, and VEGF...

We identified rare coding variants associated with Alzheimer's disease in a three-stage case-control study of 85,133 subjects. In stage 1, we genotyped 34,174 samples using a whole-exome microarray. In stage 2, we tested associated variants (P < 1 × 10(-4)) in 35,962 independent samples using de novo genotyping and imputed genotypes. In stage 3, we used an additional 14,997 samples to test the most significant stage 2 associations (P < 5 × 10(-8)) using imputed genotypes. We observed three new genome-wide significant nonsynonymous variants associated with Alzheimer's disease: a protective variant in PLCG2 (rs72824905: p...

Elevated Lipoprotein(a) (Lp(a)) plasma concentrations are a risk factor for cardiovascular disease in humans, largely controlled by the LPA gene encoding apolipoprotein(a) (apo(a)). Lp(a) is composed of low-density lipoprotein (LDL) and apo(a) and restricted to Catarrhini. A variable number of kringle IV (KIV) domains in LPA lead to a size polymorphism of apo(a) that is inversely correlated with Lp(a) concentrations. Smaller apo(a) isoforms and higher Lp(a) levels in central chimpanzees (Pan troglodytes troglodytes [PTT]) compared to humans from Europe had been reported...

BACKGROUND: Cerebral microbleeds (CMB) are MRI-demonstrable cerebral microhemorrhages (CMH) which commonly coexist with ischemic stroke. This creates a challenging therapeutic milieu, and a strategy that simultaneously protects the vessel wall and provides anti-thrombotic activity is an attractive potential approach. Phosphodiesterase 3A (PDE3A) inhibition is known to provide cerebral vessel wall protection combined with anti-thrombotic effects. As an initial step in the development of a therapy that simultaneously treats CMB and ischemic stroke, we hypothesized that inhibition of the PDE3A pathway is protective against CMH development...

SMC1A encodes one of the proteins of the cohesin complex. SMC1A variants are known to cause a phenotype resembling Cornelia de Lange syndrome (CdLS). Exome sequencing has allowed recognizing SMC1A variants in individuals with encephalopathy with epilepsy who do not resemble CdLS. We performed an international, interdisciplinary study on 51 individuals with SMC1A variants for physical and behavioral characteristics, and compare results to those in 67 individuals with NIPBL variants. For the Netherlands all known individuals with SMC1A variants were studied, both with and without CdLS phenotype...

OBJECTIVES: Salivary acinar and duct cells show different expression patterns of claudins, which may reflect their different functions. To study the role of claudins in saliva secretion, we examined alterations in the expression patterns of cell adhesion molecules in parotid glands of γ-irradiated rats and analyzed the influence of those changes on intercellular barrier function using primary cultures of parotid acinar cells. DESIGN: Rats were γ-irradiated with doses of 5, 15 or 20Gy, and expression levels of cell adhesion molecules were examined by immunoblotting analysis...

In this study, we investigated whether there is any association between the expression of FSCN1 and SNAI2 and the possible underlying mechanisms in head and neck squamous cell carcinoma (HNSC). In addition, we also investigated whether FSCN1 modulates epithelial-to-mesenchymal transition (EMT) in HNSC cells. Microarray data of dysregulated genes in HNSC were searched in GEO datasets. The association between FSCN1 expression and the 5-year/10-year overall survival (OS), as well as the correlation between the expression of FSCN1 and SOX2, MYBL2, SNAI2, STAT1, and SOX4, was analyzed based on data in TCGA HNSC cohort (TCGA-HNSC)...

Hepatocellular carcinoma (HCC) is one of the most difficult cancer disease for diagnosis and treatment, with a low survival rate and high recurrence rate and mortality. Nuclear factor of activated T-cells 5 (NFAT5) is mediated by osmolality and proved to be a carcinogenic gene in some tumor. However in our study we considered NFAT5 as tumor suppressor of HCC. RT-qPCR was performed for NFAT5 expression in tumor tissues. NaCl was applied to make hyperosmotic treatment. We knockdowned and overexpressed NFAT5 to investigate its role in HCC...

Silver nanoparticles (AgNPs) enter the central nervous system through the blood-brain barrier (BBB). AgNP exposure can increase amyloid beta (Aβ) deposition in neuronal cells to potentially induce Alzheimer disease (AD) progression. However, the mechanism through which AgNPs alter BBB permeability in endothelial cells and subsequently lead to AD progression remains unclear. This study investigated whether AgNPs disrupt the tight junction proteins of brain endothelial cells, and alter the proteomic metabolism of neuronal cells underlying AD progression in a triple cell co-culture model constructed using mouse brain endothelial (bEnd...

Claudins provide tight junction barrier selectivity. The human CLDN5 gene contains a high-frequency single-nucleotide polymorphism (rs885985), where the G allele codes for glutamine (Q) and the A allele codes for an amber stop codon. Thus, these different CLDN5 alleles define nested open reading frames (ORFs) encoding claudin-5 proteins that are 303 or 218 amino acids in length. Interestingly, human claudin-16 and claudin-23 also have long ORFs. The long form of claudin-5 contrasts with the majority of claudin-5 proteins in the National Center for Biotechnology Information protein database, which are less than 220 amino acids in length...

Malignant pleural mesothelioma (MPM) is a highly aggressive tumor primarily associated with asbestos exposure. Early detection of MPM is restricted by the long latency period until clinical presentation, the ineffectiveness of imaging techniques in early stage detection and the lack of non-invasive biomarkers with high sensitivity and specificity. In this study we used transcriptome data mining in order to determine which CLAUDIN (CLDN) genes are differentially expressed in MPM as compared to controls. Using the same approach we identified the interactome of the differentially expressed CLDN genes and assessed their expression profile...
