Project description:Exome Sequencing to Identify Medically Relevant Associations in Finnish Sub-Isolate Samples from the FINRISK Cohort
| PRJNA251914 | ENA
Project description:<p>We propose to undertake, at the McDonnell Genome Institute of Washington University, a collaborative exome sequencing project of ~10,000 samples from a large Finnish population cohort, FINRISK, a participating component of the Sequencing Initiative Suomi (SISu) consortium. Together these sequenced samples will provide a unique resource for identification of infrequent or rare variants with a large impact on cardiovascular and metabolic disorders as well as on a wide range of heritable, disease-related quantitative phenotypes. Our collaborative group has already shown, in exome sequencing studies of smaller Finnish samples, that numerous loss of function variants are dramatically more frequent in Finland compared to other European populations, and that such variants demonstrate strong associations to several disease-related traits. Finland is the largest population isolate in Europe and the enrichment of these variants reflects its rapid growth from a severe population bottleneck about 100 generations ago.</p> <p>Northern and Eastern parts of Finland experienced additional, more recent bottlenecks, and therefore the enrichment of particular high-impact variants in these regions is even more extreme (Stoll et al., 2013, PMID: <a href="https://www.ncbi.nlm.nih.gov/pubmed/23912948" target="_blank">23912948</a>). We therefore propose to focus exome sequencing efforts on about 10,000 members of FINRISK who are specifically drawn from these sub-isolate regions. As a very wide range of phenotypes are available from this cohort (including cardiovascular and metabolic disease outcomes obtained from national registries) we hypothesize that the proposed exome sequencing will identify numerous new disease-related associations. Within the National Biobanks of Finland (<a href="http://www.nationalbiobanks.fi/" target="_blank">www.nationalbiobanks.fi</a>) we have DNA and tissue samples from over 200,000 individuals of whom 50,000 have GWAS data; these samples provide an exceptional resource for both imputation from the sequencing studies proposed here, as well as for replication of associations.</p>

Project description:FITFATTWIN study identified from the FinnTwin16 Cohort, which is a population based, longitudinal study of Finnish twins born between October 1974 and December 1979. The participants had no chronic disease affecting the ability to exercise, no acute disease, and no drug or alcohol abuse.

Project description:Atrial fibrillation (AF) is a prevalent and morbid abnormality of the heart rhythm with a strong genetic component Here, we meta-analyzed genome and exome sequencing data from 36 studies that included 52,416 AF cases and 277,762 controls In burden tests of rare coding variation, we identified novel associations between AF and the genes MYBPC3, LMNA, PKP2, FAM189A2 and KDM5B We further identified associations between AF and rare structural variants due to deletions in CTNNA3 and duplications of GATA4 We broadly replicated our findings in independent samples from MyCode, deCODE and UK Biobank Finally, we found that CRISPR-knockout of KDM5B in stem cell derived atrial cardiomyocytes led to a shortening of the action potential duration and widespread transcriptomic dysregulation of genes relevant to atrial homeostasis and conduction Our results highlight the contribution of rare coding and structural variants to AF, the genetic link between AF and cardiomyopathies, and expand our understanding of the rare variant architecture for this common arrhythmia

Project description:We compared molecular characteristics of primary and recurrent pediatric ependymoma to identify sub-group specific differences. Gene expression profiles were used to identify unique immunobiologic sub-types of posterior fossa pediatric ependymoma. Gene expression profiles were generated from surgical tumor (ependymoma) (n=65) using Affymetrix HG-U133plus2 chips (Platform GPL570). Normalization was performed on our entire cohort of ependymoma. Of the 65 samples, a sub-set of 58 were used in the corresponding manuscript. Excluded samples are noted. Gene expression profiles were filtered to obtain gene expression of key immune cell markers. Comparative analyses between tumor samples were used to identifiy unique immunobiology between posterior fossa sub-groups.

Project description:Staphylococcus epidermidis, the common inhabitant of human skin and mucosal surfaces has emerged as an important pathogen in patients receiving surgical implants and medical devices. Entering the body via surgical sites and colonizing the medical devices through formation of multi-layered biofilms it leads to refractory and persistent device-related infections (DRIs). Staphylococcal proportions within biofilms are more tolerant to antibiotics and immune responses, and thus are hard-to-treat. The consequent morbidity and mortality, and economic losses in health care systems has strongly necessitated the need for development of new anti-bacterial and anti-biofilm based therapeutics. In this study, we describe the biological activity of a marine sponge-derived Streptomyces sp. SBT348 extract in restraining staphylococcal growth and biofilm formation on polystyrene, glass, medically relevant titan metal and silicone surfaces. A bio-assay guided fractionation was performed to isolate the active compound (C3) from the crude SBT348 extract. Our results demonstrated that C3 effectively inhibits the growth (MIC: 31.25 µg/ml) and biofilm formation (sub-MIC range: 1.95-<31.25 µg/ml) of S. epidermidis RP62A in vitro. Chemical characterization of C3 by heat and enzyme treatments, and High-Resolution Fourier Transform Mass Spectrometry (HRMS) revealed its heat-stable and non-proteinaceous nature, and high molecular weight (1258. 3257 Da). Cytotoxicity profiling of C3 in vitro on mouse fibroblast (NIH/3T3) and macrophage (J774.1) cell lines, and in vivo on the greater wax moth larvae Galleria melonella revealed its non-toxic nature at the effective dose. Transcriptome analysis of C3 treated-S. epidermidis RP62A has further unmasked the negative effect of C3 on central metabolism (carbon, amino acid and protein, lipids, nucleotide and energy) suggesting its mode of action. Taken together, these findings suggest that C3 could be possibly used as antibacterial and antibiofilm coatings on medically-relevant surfaces and prevent the relapsing staphylococcal DRIs.

Project description:We have performed a comparative genomic hybridization of 10 adult-type Ovarian Granulosa Cell tumors (GCTs) to obtain a picture of the genomic landscape of this cancer type and to identify new candidate driver genes. The samples are the somatic genomic DNA of 10 ovarian GCTs obtained from finnish patients. The reference DNA is an equimolar mix of genomic DNA from 10 finnish (ethnically-matched to sample DNAs) non-affected Females.
