Abstract
RPS14, CSNK1A1, and miR-145 are universally co-deleted in the 5q- syndrome, but mouse models of each gene deficiency recapitulate only a subset of the composite clinical features. We analyzed the combinatorial effect of haploinsufficiency for Rps14, Csnk1a1, and miRNA-145, using mice with genetically engineered, conditional heterozygous inactivation of Rps14 and Csnk1a1 and stable knockdown of miR-145/miR-146a. Combined Rps14/Csnk1a1/miR-145/146a deficiency recapitulated the cardinal features of the 5q- syndrome, including (1) more severe anemia with faster kinetics than Rps14 haploinsufficiency alone and (2) pathognomonic megakaryocyte morphology. Macrophages, regulatory cells of erythropoiesis and the innate immune response, were significantly increased in Rps14/Csnk1a1/miR-145/146a deficient mice as well as in 5q- syndrome patient bone marrows and showed activation of the innate immune response, reflected by increased expression of S100A8, and decreased phagocytic function. We demonstrate that Rps14/Csnk1a1/miR-145 and miR-146a deficient macrophages alter the microenvironment and induce S100A8 expression in the mesenchymal stem cell niche. The increased S100A8 expression in the mesenchymal niche was confirmed in 5q- syndrome patients. These data indicate that intrinsic defects of the 5q- syndrome hematopoietic stem cell directly alter the surrounding microenvironment, which in turn affects hematopoiesis as an extrinsic mechanism.

Abstract
BACKGROUND Nasal polyposis (NP) is a chronic inflammatory disease that is frequently associated with allergy and asthma. Corticosteroid therapy and surgical removal of polyps are the 2 most common treatment strategies for NP. Various allergic and inflammatory mediators are thought to play a major role in the pathophysiology of this disorder. The CD14 gene is located on chromosome 5q31-32, which is considered a critical region for several allergic and atopic diseases, including asthma. Consequently, variations in CD14 could have functional effects on the etiology and severity of allergy and asthma. The aim of this study was to investigate the association between the polymorphism C-159T in the CD14 gene of patients with NP and controls. METHODS The study population comprised 106 patients with NP diagnosed based on computed tomography scan of the paranasal sinus, endoscopy, and histological examination. Findings were compared with those from 87 controls. The frequency of C-159T was determined using polymerase chain reaction-restriction fragment length polymorphism analysis. DNA was extracted using the salting out technique. RESULTS A significant association was observed between C-159T and NP (P = .04). Patients with the CC genotype at position -159 of the CD14 promoter region had an increased risk of asthma (OR, 3.83, 95% CI, 0.99-13.91; P < .02). However, we did not find an association between the distribution of C-159T and serum immunoglobulin E level. CONCLUSIONS A genetic variation in the CD14 promoter might play a role in the pathogenesis of NP and in the incidence of asthma.

Abstract
BACKGROUND AND METHODS Numerous genetic studies have mapped asthma susceptibility genes to a region on chromosome 5q31-33 in several populations. This region contains a cluster of cytokines and other immune-related genes important in immune response. In the present study, to determine the genetic variations and patterns of linkage disequilibrium (LD), we resequenced all the exons and promoter regions of the 29 asthma candidate genes in the chromosome 5q31-33 region. RESULTS We identified a total of 314 genetic variants, including 289 single nucleotide polymorphisms (SNPs), 22 insertion/deletion polymorphisms and 3 microsatellites. Standardized variance data for allele frequency revealed substantial differences in SNP allele frequencies among different ethnic groups. Interestingly, significant ethnic differences were observed mainly in intron SNPs. LD block analysis using 174 common SNPs with a frequency of >10% disclosed strong LD within most candidate genes. No significant LD was observed across genes, except for one LD block (CD14-IK block). Gene-based haplotype analyses showed that 1-5 haplotype-tagging SNPs may be used to define the six or fewer common haplotypes with a frequency of >5%, regardless of the number of SNPs. CONCLUSION Overall, our results provide useful information for the identification of immune-mediated disease genes in the chromosome 5q31-33 region, as well as valuable evidence for gene-based haplotype analysis in disease association studies.

Abstract
Previous studies have suggested a role for interleukin-4 gene (IL4) in susceptibility to multiple sclerosis (MS) as well as other autoimmune diseases. We screened the promoter region, exons 1-4 and their splice sites for polymorphisms and tested the association between novel polymorphisms E1(33)*C-->T and I3(2580)*C-->A, and the established 5'(-523)*C-->T and I3(709)*VNTR polymorphisms with susceptibility to, age of onset in, and course and severity of MS in sporadic cases. I3(709)*VNTR was associated with susceptibility to MS (p=0.004) due to a dearth of heterozygotes in patients (29/122; 23.8%) compared to controls (91/244; 37.3%). Homozygotes for the uncommon I3(709)*allele-2 may have increased susceptibility (p=0.044; OR=5.17, 95% CI: 0.83-54.95) as might carriers for the extended haplotypes 5'(-523)*T/E1(33)*T/I3(709)*allele-2/I3(2580)*C (p=0.003; OR: 3.75, 95% CI: 1.18-11.93) or 5'(-523)*C/E1(33)*C/I3(709)*allele-1/I3(2580)*A (p=0.004; OR: 4.22, 95% CI: 1.22-14.54). We could not confirm the previously reported association between carriage of I3(709)*allele-2 and older age of onset. However, we found a trend for association between the homozygous state for this allele and older age of onset.

Abstract
A new murine chemokine was identified in a search for glucocorticoid-attenuated response genes induced in the lung during endotoxemia. The first 73 residues of the predicted mature peptide are 71% identical and 93% similar to human CXCL11/IFN-inducible T cell alpha chemoattractant (I-TAC) (alias beta-R1, H174, IFN-inducible protein 9 (IP-9), and SCYB9B). The murine chemokine has six additional residues at the carboxyl terminus not present in human I-TAC. Identification of this cDNA as murine CXCL11/I-TAC is supported by phylogenetic analysis and by radiation hybrid mapping of murine I-TAC (gene symbol Scyb11) to mouse chromosome 5 close to the genes for monokine induced by IFN-gamma (MIG) and IP10. Murine I-TAC mRNA is induced in RAW 264.7 macrophages by IFN-gamma or LPS and is weakly induced by IFN-alphabeta. IFN-gamma induction of murine I-TAC is markedly enhanced by costimulation with LPS or IL-1beta in RAW cells and by TNF-alpha in both RAW cells and Swiss 3T3 fibroblasts. Murine I-TAC is induced in multiple tissues during endoxemia, with strongest expression in lung, heart, small intestine, and kidney, a pattern of tissue expression different from those of MIG and IP10. Peak expression of I-TAC message is delayed compared with IP10, both in lung after i.v. LPS and in RAW 264.7 cells treated with LPS or with IFN-gamma. Pretreatment with dexamethasone strongly attenuates both IFN-gamma-induced I-TAC expression in RAW cells and endotoxemia-induced I-TAC expression in lung and small intestine. The structural and regulatory similarities of murine and human I-TAC suggest that mouse models will be useful for investigating the role of this chemokine in human biology and disease.

Abstract
Interleukins -4, -5, and -13, cardinal cytokines produced by Th2 cells, are coordinately expressed and clustered in 150-kb syntenic regions on mouse chromosome 11 and human chromosome 5q31. We analyzed two sets of human yeast artificial chromosome transgenic mice that contained the 5q31 cytokines to assess whether conserved sequences required for their coordinate and cell-specific regulation are contained within the cytokine cluster itself. Human IL-4, IL-13, and IL-5 were expressed under Th2, but not Th1, conditions in vitro. Each of these cytokines was produced during infection with Nippostrongylus brasiliensis, a Th2-inducing stimulus, and human IL-4 was generated after activation of NK T cells in vivo. Consistently fewer cells produced the endogenous mouse cytokines in transgenic than in control mice, suggesting competition for stable expression between the mouse and human genes. These data imply the existence of both conserved trans-activating factors and cis-regulatory elements that underlie the coordinate expression and lineage specificity of the type 2 cytokine genes in lymphocytes.

Abstract
BACKGROUND Linkage studies mapped a locus regulating total serum IgE concentrations in a noncognate fashion to chromosome 5q31 and a locus for atopy to chromosome 11q13. In contrast, antigen-driven IgE production seems to be largely controlled by major histocompatibility complex class II genes. OBJECTIVE We therefore analyzed the association between the phenotype of high IgE serum levels and six microsatellite markers on chromosomes 5q31 and 11q13, as well as HLA-DRB1, in a random sample of the adult East German population. METHODS One hundred twenty-nine persons identified as "cases" (serum IgE level > 200 kU/L) and 266 control subjects (serum IgE level < or = 200 kU/L) were genotyped for five 5q31 microsatellites (D5S436, D5S393, D5S210, IL-4, and IL-9) and an 11q13 microsatellite (FCERIB). Cases and controls were also typed for HLA-DRB1. Allele frequencies were compared between cases and controls by means of a two-sided Fisher's exact test. RESULTS None of the markers was significantly associated although a weak association to the markers within the IL-9 gene and the FCER1B gene and to the HLA-DRB1*01 allele was found when specific IgE-positive cases were compared with negative controls. CONCLUSIONS The weak associations observed after stratification for specific IgE might point to a contribution of genes in these regions to the development of allergy.

Abstract
Using a human-mouse monochromosomal hybrid, BG15-6, that contains an intact human chromosome 5, we isolated four monoclonal antibodies, 2A10, 3H9, 5G9, and 6G12, as chromosome marker antibodies recognizing cell surface antigens specific for human chromosome 5. The binding patterns of these antibodies to BG15 subclones containing fragments of human chromosome 5 indicated that 2A10, 3H9, and 6G12 recognized the antigens produced by genes located on 5pter-q22, and that 5G9 recognized the antigen produced by a gene located on 5q23. Cells containing human chromosome 5 were very effectively sorted in a fluorescence-activated cell sorter (FACS) using monoclonal antibody 6G12. This method for sorting cells containing human chromosome 5 or an appropriate fragment of this chromosome from among human-rodent hybrid cells should be very useful in studies on gene expression, gene cloning and gene mapping.
