BACKGROUND AND AIM: NOD1/CARD4 and NOD2/CARD15 are members of the Nod-like receptor (NLR) family, and they contain a caspase recruitment domain (CARD). NLRs are located in the cytosol where they bind bacterial and viral ligands and play a key role in the innate and adaptive immune response, apoptosis, autophagy, and reactive oxygen species generation. NLR gene polymorphisms may shift the balance between pro- and anti-inflammatory cytokines and modulate the risk of infection, chronic inflammation, and cancer...

The expression of apoptosis genes in a commercial pre-designed low-density array from Applied Biosystems was evaluated in two human brain cancer cell models, LN-18 and Daoy (HTB-186™) in comparison to the reference human primary endothelial cells under basic conditions. Analysis of the gene expression in the cancer cell lines compared to the normal control revealed features reflecting anti-apoptotic and inflammatory characteristics of the former. There was an overall downregulation of apoptosis-stimulating genes in both cancer cell lines, along with an upregulation of certain apoptosis inhibitors...

Apoptosis-antagonizing transcription factor (AATF) is involved in transcriptional regulation, cell cycle control, DNA damage responses and in the execution of cell death programs. It also interacts directly with nuclear hormone receptors to enhance their transactivation. This study highlights the RNomics of AATF gene in the pathogenesis of breast cancer: RNA interference gave 64% reduction in AATF mRNA and 47% decline in AATF protein expression in MCF-7 breast cancer cells. Cell proliferation decreased by 41% after transfection and was accompanied by apoptosis induction in 30% MCF-7 cells...

BACKGROUND: Hay fever or seasonal allergic rhinitis (AR) is a chronic disorder associated with IgE sensitization to grass. The underlying genetic variants have not been studied comprehensively. There is overwhelming evidence that those who have older siblings have less AR, although the mechanism for this remains unclear. OBJECTIVE: We sought to identify common genetic variant associations with prevalent AR and grass sensitization using existing genome-wide association study (GWAS) data and to determine whether genetic variants modify the protective effect of older siblings...

NOD1/CARD4 and NOD2/CARD15 are members of Nod-like receptor family. They are located in cytosol, bind bacterial and viral ligands and play a key role in realization of innate and adaptive immune response, apoptosis, autophagy, and reactive oxygen species generation. Polymorphisms in NOD1/CARD4 and NOD2/CARD15 genes may shift balance between pro- and anti-inflammatory cytokines, modulating the risk of infection, chronic inflammation and cancer. NOD1/CARD4 and NOD2/CARD15 gene polymorphisms may be associated with altered risk of gastric, colorectal, breast, ovarian, prostate, testicular, lung, laryngeal, liver, gallbladder, biliary tract, pancreatic, small bowel, kidney, urinary bladder cancer, skin cancer, nonthyroid endocrine tumors, lymphoma and leukemia...

BACKGROUND AND AIM: The nucleotide-binding oligomerization domain-1 (NOD1) gene encodes a pattern recognition receptor that senses pathogens. NOD1/caspase recruitment domain (CARD4) signaling leads to the activation of nuclear factor-kB, and plays an important role in innate immunity. Certain polymorphisms and mutations in NOD1/CARD4 might result in a dysfunctional innate immune response during bacterial recognition, which might have direct implications in inflammatory bowel disease (IBD) pathogenesis...

The cytosolic nucleotide-binding oligomerization domain 1 (NOD1)/CARD4 and NOD2/CARD15 proteins are members of NOD-like receptors recognizing specific motifs within peptidoglycans of both Gram-negative and Gram-positive bacteria. NOD1 and NOD2 signal via the downstream adaptor serine/threonine kinase RIP2/CARDIAK/RICK to initiate NF-kappaB activation and the release of inflammatory cytokines/chemokines. In this report, we show that 5,6-dimethylxanthenone-4-acetic acid (DMXAA), a cell-permeable, small molecule that has anti-tumor activity, can also activate NOD1 and NOD2...

BACKGROUND: Variation in genes involved in the innate immune response may play a role in the predisposition to colorectal cancer (CRC). Several polymorphisms of the CARD15 gene (caspase activating recruitment domain, member 15) have been reported to be associated with an increased susceptibility to Crohn disease. Since the CARD15 gene product and other CARD proteins function in innate immunity, we investigated the impact of germline variation at the CARD4, CARD8 and CARD15 loci on the risk for sporadic CRC, using a large patient sample from Northern Germany...

Curcumin, a natural product isolated from the plant Curcuma longa, has a diverse range of molecular targets that influence numerous biochemical and molecular cascades. Curcumin has been shown to inhibit nuclear factor kappaB (NF-kappaB) activation at several steps in the NF-kappaB signaling pathways and thereby controls numerous NF-kappaB-regulated genes involved in various diseases. In the present study, we investigated the effect of curcumin pretreatment on 84 tumor necrosis factor-alpha (TNF-alpha)-activated genes of NF-kappaB pathways in K562 cells, using a real-time PCR array...

OBJECTIVES: Churg-Strauss syndrome (CSS) is a rare necrotizing vasculitis associated with asthma, blood and tissue eosinophilia and granuloma formation. We wondered whether eosinophil accumulation in CSS results from the defect of intrinsic apoptosis pathway in blood eosinophils, leading to their prolonged survival. METHODS: We analysed immunophenotype (flow cytometry), expression of apoptosis-related genes (real-time PCR) and spontaneous apoptosis in blood eosinophils isolated from nine patients in exacerbation (active CSS), seven patients in remission (inactive CSS) and 14 matched healthy subjects...

Serological biomarkers in inflammatory bowel disease (IBD) are a rapidly expanding list of non-invasive tests for objective assessments of disease activity, early diagnosis, prognosis evaluation and surveillance. This review summarizes both old and new biomarkers in IBD, but focuses on the development and characterization of new serological biomarkers (identified since 2007). These include five new anti-glycan antibodies, anti-chitobioside IgA (ACCA), anti-laminaribioside IgG (ALCA), anti-manobioside IgG (AMCA), and antibodies against chemically synthesized (Sigma) two major oligomannose epitopes, Man alpha-1,3 Man alpha-1,2 Man (SigmaMan3) and Man alpha-1,3 Man alpha-1,2 Man alpha-1,2 Man (SigmaMan4)...

The volume of research undertaken on the genetic susceptibility of inflammatory bowel disease (IBD) has been tremendous. Genome-wide linkage studies pointed towards more than 10 chromosomal regions and fine-mapping of these regions led to the identification of a number of genes, including CARD15 (NOD2), DLG5, OCTN1 and 2, TLR4 and CARD4 (NOD1). With the recent completion of the human genome project, whole genome association studies (WGAS) have now become possible and have identified additional genes (IL23R, IRGM, PTGER4, ATG16L1) for Crohn's disease and ulcerative colitis, that have subsequently been replicated...

Antibodies against different microbial epitopes are associated with disease phenotype, may be of diagnostic importance and may reflect a loss of tolerance in Crohn's disease (CD). Recently, an association was reported between the presence of these antibodies and mutations in pattern receptor genes. Our aim was to investigate whether mutations in various genes other than NOD2/CARD15 or TLR4 associated with CD (NOD1/CARD4, DLG5 and DEFB1) may influence the presence of antibodies against bacterial proteins and carbohydrates in a Hungarian cohort of CD patients...

Genetic factors play a significant role in determining inflammatory bowel disease (IBD) susceptibility. Epidemiologic data support genetic contribution to the pathogenesis of IBD, which include familial aggregation, twin studies, racial and ethnic differences in disease prevalence. Linkage studies have identified several susceptibility genes contained in different genomic regions named IBD1 to IBD9. Nucleotide oligomerization domain (NOD2) and human leukocyte antigen (HLA) genes are the most extensively studied genetic regions (IBD1 and IBD3 respectively) in IBD...

Atopic dermatitis (AD) is a chronic skin disease affecting up to 15% of children in industrialized countries. AD belongs to the group of atopic disorders characterized by excessive immune reactions to ubiquitous antigens. Complex interactions between genetic and environmental factors have been suggested for atopic disorders. Dysregulation of the innate immune system appears crucial for the pathogenesis of AD. The NACHT-LRRs (NLRs) represent a group of innate immune receptors with special relevance for inflammatory processes...
