MiRNA profiling of HPCX1 linked prostate cancer patients and their healthy brothers

ABSTRACT: MicroRNA expression levels in the lymphoblastic cells of prostate cancer patients and their healthy brothers from HPCX1 linked prostate cancer families were analyzed to trace variants that might alter miRNA expression and explain partly an inherited genetic predisposion to prostate cancer. MicroRNA expression levels in lymphoblastoid cell lines were detected using an Agilent Human miRNA V2 Oligo Microarray Kit (Agilent Technologies).100 ng of total RNA was used as a starting material, and miRNAs were labeled using the Agilent miRNA Labeling Kit. Labeled RNA was hybridized to Agilent miRNA arrays with eight identical arrays per slide, with each array containing probes directed against 723 human and 76 human viral miRNAs. Slides were scanned (Agilent microarray scanner) after hybridization and data was extracted using Feature Extraction software, version 9.5.1. (Agilent Technologies). Altogether 14 cancer patients and 15 healthy brothers from 11 families were included with no replicates.

<h4>Background</h4>Several predisposition loci for hereditary prostate cancer (HPC) have been suggested, including HPCX1 at Xq27-q28, but due to the complex structure of the region, the susceptibility gene has not yet been identified.<h4>Methods</h4>In this study, nonsense-mediated mRNA decay (NMD) inhibition was used for the discovery of truncating mutations. Six prostate cancer (PC) patients and their healthy brothers were selected from a group of HPCX1-linked families. Expression analyses wer ...[more]

Project description:BACKGROUND Familial diarrheas are mostly severe recessive diseases. Here we describe the clinical picture and dominant genetic cause of a novel disease in 32 members of a Norwegian family. The chronic diarrhea is of early onset, relatively mild, and is combined with increased susceptibility to intestinal inflammation, ileus and oesophagitis. METHODS Whole genome SNP-analysis was used to identify a single candidate locus for dominant diarrhea on chromosome 12, followed by sequencing of the GU2CY gene. This encodes guanylyl cyclase 2C, an intestinal receptor for bacterial heat-stable enterotoxins and the peptides uroguanylin and guanylin. Functional studies of a missense mutation were performed after heterologous expression of the mutant receptor in HEK293T cells. The therapeutic response to metformin, an inhibitor of the cystic fibrosis transmembrane regulator (CFTR), was investigated in 5 patients. RESULTS We identified heterozygosity for the first described pathogenic human mutation (c.2519G>T ) in the GUCY2C gene. The mutant receptor showed increased cGMP production in response to its ligands. This may cause hyperactivation of the CFTR and consequent increased chloride and water secretion from the enterocytes, resulting in chronic diarrhea. Treatment with the CFTR-inhibitor metformin significantly reduced the frequency of stools in affected individuals by 34-45%. CONCLUSIONS Increased GC-C signaling disturbs normal bowel function, as shown by the diverse symptoms in our patients, and seems to have a pro-inflammatory effect, either through increased Cl- secretion or additional effects of elevated cellular cGMP. The importance of genetic variants in the GC-C-CFTR-pathway for conditions like Crohn’s disease and IBS should be further explored. Linkage analysis was performed (Allegro v 2.0) using Affymetrix 250K SNP arrays according to the manufacturer's directions on DNA extracted from peripheral blood samples. This accession number contains the data for 25 individuals of family branch A in the article.

Project description:Intense immunosuppression followed by autologous hematopoietic stem cell transplantation (aHSCT) is a potential treatment for patients suffering from aggressive multiple sclerosis (MS). However it remains unresolved whether autologous CD34+ hematopoietic progenitor cells of MS patients show gene expression differences prior to aHSCT that indicate a preset proinflammatory state, which would then also predispose to or predetermine recurrence of the autoimmune disease. To approach this key point we compared the gene expression signature of CD34+ and CD34- cells collected from MS patients and healthy donors (HD). Whole genome gene expression of CD34+ and CD34- cells was analysed with the Human 4x44K Design Array (Agilent-Technologies). As main observation we found only minor differences in the gene expression signature of MS patients compared to HD. Only a single gene, troponin-type-1 (TNNT1), reached statistical significance after correction for multiple comparisons (logFC=3.1, p<0.01). There was a decreased expression of several protease genes, myeloperoxidase (MPO), neutrophil-elastase (ELA2), cathepsin-G (CTSG) and serine-protease 21 (PRSS21) in HPCs of MS patients, albeit not reaching statistical significance. In summary we did not detect substantial alterations in the gene expression profile of CD34+ HPCs in MS. Our data support the use of autologous hematopoietic stem cell transplantation for treatment of an autoimmune disease. Samples of CD34+ cells were obtained from 4 female MS patients and 4 age matched healthy donors (3 female) mobilized by G-CSF (2x5M-NM-<g/kg/day) and 4 MS patients (2 female) mobilized by G-CSF (5M-NM-<g/kg/day) plus Cyclophosphamide (Cy, 4g/m2). White blood cells, containing the CD34+ cell fraction, were collected by leucocytapheresis from peripheral blood, frozen and stored in liquid nitrogen. All samples were thawed and processed at one center and CD34+ HPCs purified by magnetic bead separation using the autoMACS system (Miltenyi). Purity and viability of CD34+ cells was analyzed by Fluorescence Activated Cell Sorter (FACS). Total cellular RNA were extracted with TRIzol reagent and analyzed with the Human 4x44K Design Array (Agilent-Technologies).

Project description:Genetics of gene expression (eQTLs or expression QTLs) has proved an indispensable tool for understanding biological pathways and pathomechanisms of trait associated SNPs. However, power of most genome-wide eQTL studies is still limited. We performed a large eQTL study in peripheral blood mononuclear cells of 2,112 individuals increasing the power to detect trans-effects genome-wide. Going beyond univariate SNP-transcript associations, we analyse relations of eQTLs to biological pathways, polygenetic effects of expression regulation, trans-clusters, and enrichment of co-localised functional elements. We found eQTLs for about 85% of analysed genes, 18% of genes were trans-regulated. Local eSNPs were enriched up to a distance of 5 MB to the transcript challenging typically implemented ranges of cis-regulations. Pathway enrichment within regulated genes of GWAS-related eSNPs supported functional relevance of identified eQTLs. We demonstrate that nearest genes of GWAS-SNPs might often be misleading functional candidates. We identified novel trans-clusters of potential functional relevance for GWAS-SNPs of several phenotypes including obesity-related traits, HDL-cholesterol levels, and haematological phenotypes. We used chromatin immunoprecipitation data for demonstrating biological effects. We show for strongly heritable transcripts that a considerable gap still exists between total heritability resulting from all trans-chromosomes and explained variance of all identified trans-eSNPs. In contrast, the vast majority of most cis-heritability of these genes is already explained. Dissection of co-localised functional elements indicated a prominent role of SNPs in loci of pseudogenes and non-coding RNAs for the regulation of coding genes. In summary, our study substantially increases the catalogue of human eQTLs and improves our understanding of the complex genetic regulation of gene-expression, pathways and disease related processes. Gene expression from human blood mononuclear cells from individuals of the Leipzig LIFE Heart Study was analyzed applying Illumina HT-12 v4 Expression BeadChips. After preprocessing, 28,295 expression probes for 2,112 individuals remained for analysis. In a population-based analysis, we identified associations between DNA variants and RNA expression levels and characterized these findings.
