  1. ...conserved genomic clusters, which contain two or more maternally and paternally expressed genes in large regions of up to several megabases in size (Table 1; Fig. 1).View larger version: In this window In a new window Figure 1. Schematic representation of the genomic organization of the 10 largest imprinted...
  2. ...properties of topologically associating domains (TADs) are overall maintained, significant changes occur in the organization of compartments and subcompartments. These changes are closely correlated with alterations in the expression of oncogenic genes. We also observe a restructuring of TAD–TAD interactions...
  3. ...Genetic variation in recalcitrant repetitive regions of the Drosophila melanogaster Harsh G. Shukla1,2, Mahul Chakraborty3 and J.J. Emerson1,4 1Department of Ecology and Evolutionary Biology, University of California Irvine, Irvine, California 92697, USA; 2Graduate Program in Mathematical...
  4. ...a large block of genes, the class III region, between MHC-I and its associated APGs (which remained with class II), disrupting their physical linkage. This structural change is thought to have lifted the coevolutionary constraint, allowing for the emergence of a multigene MHC-Ia family and generalist APGs...
  5. ...are therefore likely to impact evolution of gene regulation. Yet, the role of TEs in regulatory evolution after WGDs is not well understood. Here we used Atlantic salmon as a model system to explore how TE activity after the salmonid WGD ∼100 MYA shaped CRE evolution. We identified 55,080 putative TE-CREs using...
  6. ...that modulate gene expression by binding transcription 16 factors (TFs). While enhancers and transcription factor binding sites (TFBS) have been 17 identified for several immune responsive genes in Drosophila, most enhancers that regulate 18 immune-induced genes are unknown. By identifying enhancers, we can...

  7. ...enrichment despite lacking well-positioned nucleosomes (Fig. 3E). This noncanonical H3K27me3 enrichment resembles the pattern observed in female Drosophila GSCs, in which H3K27me3 is detectable at both inactive and active gene loci (DeLuca et al. 2020).In contrast, in CySC-like cells, H3K27me3 is most...
  8. ...s (Van de Peer et al. 2009; Kondrashov 2012; Wang et al. 2012). Although increased ploidy following WGD incurs fitness costs to an organism, it can confer advantages during times of environmental change and stress, including increased adaptability and robustness of gene regulatory networks (Ebadi et...
  9. ...Transposable elements contribute to the evolution of host shift–related genes in cactophilic Drosophila species Daniel Siqueira de Oliveira1,2,3, Anaïs Larue2, William Vilas Boas Nunes2, Francois Sabot4, Alejandra Bodelón5, María Pilar García Guerreiro5, Cristina Vieira2 and Claudia Marcia...
