The paper establishes hybrid Drosophila cell lines to study genome instabilities and identifies incompatibility genes and chromosomal regions prone to loss in hybrids.

The paper shows that variant RING1 complexes in Drosophila can ubiquitylate H2A without being part of the Polycomb repression system, and that H2A ubiquitylation has minimal impact on transcriptional repression.

The paper develops a computational model to forecast H3K27 methylation dynamics in Drosophila with high temporal resolution and shows that PRC2 activity and replication frequency define methylated H3K27 pools.

The paper identifies DNA elements that tether canonical PRC1 to human genes and shows differences in sequence features compared to PRC2 binding.

The paper uses a Monte Carlo-Molecular Dynamics simulation to show that PRC1 interaction with H3K27me3 causes chromatin folding and DNA element clustering.

The paper identifies hundreds of Drosophila chromatin insulator elements dependent on Cp190 and CTCF by analyzing genomic contacts, transcriptomes, and protein binding in deficient cells.

The paper identifies variant Polycomb complexes in Drosophila, supporting their ancient functional diversity through proteomic analyses.

This study investigates the role of H3K36 methylation and methyltransferases in chromosome-specific gene regulation in Drosophila, showing their importance in balancing transcriptional output for the male X-chromosome and 4th chromosome.

The paper identifies head-to-tail DNA template insertions in CRISPR/Cas9 editing and highlights the failure of PCR to detect them, advocating for comprehensive analysis.

This study identifies the domains of Ash1 required to counteract Polycomb repression in Drosophila, showing that the BAH, PHD, and SET domains are essential while AT hooks are not.

The paper identifies a PRC1 targeting element (PTE) and CpG-island that together form a Polycomb Response Element for the CCND2 oncogene, showing their role in coordinating PRC1 and PRC2 recruitment.
