Abstract

Delineating the pathogenesis of complex genetic diseases is complicated by the great variety of genetic loci, genes, cell types, environmental factors and tissues that are involved. The genetic background of complex genetic diseases has been intensively studied through genome wide association studies (GWASs). This led to the association of many genetic loci to a multitude of diseases. The identification of causal variants and affected genes has proven difficult, thereby leaving some pathogenic mechanismsunresolved and potential therapeutic targets unrevealed. In this thesis, we study the involvement of DNA regulatory elements (DRE) in the pathogeneses of complex genetic diseases and epithelial mechanisms that are potentially involved in inflammatory bowel disease (IBD). In the first part of this thesis we studied loci associated to IBD, CVD cardiovascular diseases) and CKD (chronic kidney disease). We show that disease associated loci are enriched for active DRE and we used chromatin conformation capture to study the 3D configuration of these loci. Through this approach we identified many novel candidate genes, pathways and key regulators of IBD, CVD and CKD.Genetic studies on IBD have shown that the intestinal epithelium plays a important role in the pathogenesis of this complex genetic disease. Therefore, in the second part of this thesis, we use human intestinal organoids to study the interaction between bacterial antigens and the intestinal epithelium. We show that intestinal stem cells are a major source of the inflammatory response and that the responsiveness of the epithelium is regulated at the post-transcriptional level.

Abstract

BACKGROUND & AIMS: The contribution of genetic factors to the pathogenesis of inflammatory bowel disease (IBD) has been established by twin, targeted-sequencing, and genome-wide association studies. These studies identified many risk loci, and research is underway to identify causal variants. These studies have focused mainly on protein-coding genes. We investigated other functional elements in the human genome, such as regulatory regions.METHODS: Using acetylated histone 3 lysine 27 chromatin immunoprecipitation and sequencing, we identified tens of thousands of potential regulatory regions that are active in intestinal epithelium (primary intestinal crypts and cultured organoids) isolated from resected material and from biopsies collected during ileo-colonoscopies and immune cells (monocytes, macrophages, CD34(+), CD4(+), and CD8(+)). We correlated these regions with susceptibility loci for IBD.RESULTS: We have generated acetylated histone 3 lysine 27 profiles from primary intestinal epithelium and cultured organoids, which we have made publically available. We found that 45 of 163 single nucleotide polymorphisms (SNPs) associated with IBD overlap specifically with active regulatory elements. In addition, by taking strong linkage disequilibrium into account, another 47 IBD-associated SNPs colocalized with active regulatory elements through other SNPs in their vicinity. Altogether, 92 of 163 IBD-associated SNPs correlated with distinct active regulatory elements-a frequency 2.5- to 3.5-fold greater than that expected from random sampling. The variations in these SNPs often create or disrupt known binding motifs; they might affect the binding of transcriptional regulators to alter expression of regulated genes.CONCLUSIONS: In addition to variants in protein coding genes, variants in noncoding DNA regulatory regions that are active in intestinal epithelium and immune cells are potentially involved in the pathogenesis of IBD.

Abstract

Stress granules (SGs) are cytoplasmic assemblies in response to a variety of stressors. We report a new neurodevelopmental disorder (NDD) with common features of language problems, intellectual disability, and behavioral issues caused by de novo likely gene-disruptive variants in UBAP2L , which encodes an essential regulator of SG assembly. Ubap2l haploinsufficiency in mouse led to social and cognitive impairments accompanied by disrupted neurogenesis and reduced SG formation during early brain development. On the basis of data from 40,853 individuals with NDDs, we report a nominally significant excess of de novo variants within 29 genes that are not implicated in NDDs, including 3 essential genes ( G3BP1 , G3BP2 , and UBAP2L ) in the core SG interaction network. We validated that NDD-related de novo variants in newly implicated and known NDD genes, such as CAPRIN1 , disrupt the interaction of the core SG network and interfere with SG formation. Together, our findings suggest the common SG pathology in NDDs.

Abstract

Genome-wide association studies (GWASs) have identified many genetic risk factors for CKD. However, linking common variants to genes that are causal for CKD etiology remains challenging. By adapting self-transcribing active regulatory region sequencing, we evaluated the effect of genetic variation on DNA regulatory elements (DREs). Variants in linkage with the CKD-associated single-nucleotide polymorphism rs11959928 were shown to affect DRE function, illustrating that genes regulated by DREs colocalizing with CKD-associated variation can be dysregulated and therefore, considered as CKD candidate genes. To identify target genes of these DREs, we used circular chromosome conformation capture (4C) sequencing on glomerular endothelial cells and renal tubular epithelial cells. Our 4C analyses revealed interactions of CKD-associated susceptibility regions with the transcriptional start sites of 304 target genes. Overlap with multiple databases confirmed that many of these target genes are involved in kidney homeostasis. Expression quantitative trait loci analysis revealed that mRNA levels of many target genes are genotype dependent. Pathway analyses showed that target genes were enriched in processes crucial for renal function, identifying dysregulated geranylgeranyl diphosphate biosynthesis as a potential disease mechanism. Overall, our data annotated multiple genes to previously reported CKD-associated single-nucleotide polymorphisms and provided evidence for interaction between these loci and target genes. This pipeline provides a novel technique for hypothesis generation and complements classic GWAS interpretation. Future studies are required to specify the implications of our dataset and further reveal the complex roles that common variants have in complex diseases, such as CKD., (Copyright © 2018 by the American Society of Nephrology.)
