Project description:The three-dimensional organization of chromatin has a critical impact on the regulation of gene expression. However, little is known about the effect of DNA copy number variants (CNVs) on chromatin organization. We performed an allele-specific chromatin conformation and gene expression analysis of wild-type (WT) mouse chromosome 4 and an engineered 4.3Mb chromosome 4 deletion in mouse embryonic fibroblasts. A newly developed quantitative framework for the analysis of paired-end 4C-seq data revealed a number of significant differentially interacting regions (DIRs) and higher-order chromatin compaction changes present in the deletion chromosome. Selected DIRs were validated by 3D DNA FISH experiments. We discovered a significant enrichment of CTCF and Smc1 binding sites within DIRs, as well as differentially expressed genes determined by RNA-Seq. Together, our findings highlight the complex effects of a 4E2 CNV on chromatin structure and function, both locally in the deletion chromosome and globally in the WT copy.

Project description:Copy-number variants (CNVs) are large-scale amplifications or deletions of DNA that can drive rapid adaptive evolution and result in large-scale changes in gene expression. Whereas alterations in the copy number of one or more genes within a CNV can confer a selective advantage, other genes within a CNV can decrease fitness when their dosage is changed. Dosage compensation - in which the gene expression output from multiple gene copies is less than expected - is one means by which an organism can mitigate the fitness costs of deleterious gene amplification. Previous research has shown evidence for dosage compensation at both the transcriptional level and at the level of protein expression; however, the extent of compensation differs substantially between genes, strains, and studies. Here, we investigated sources of dosage compensation at multiple levels of gene expression regulation by defining the transcriptome, translatome and proteome of experimentally evolved yeast (Saccharomyces cerevisiae) strains containing adaptive CNVs.
