The piRNA pathway regulates satellite DNAs in the Drosophila melanogaster germline and affects heterochromatin establishment at pericentromeric satellite DNA in embryos, implying a general role for piRNAs in ensuring genome stability.

RNA polymerase recruits the PcrA DNA helicase via a conserved interaction motif in order to remove R-loops and prevent conflicts with replication.

FLT3-ITD/STAT5A signaling is more sensitive to Dot1L inhibition than the canonical MLL-fusion activated drivers of leukemogenesis, providing a potential therapeutic avenue for one of the most frequent lesions in leukemia.

DNA loops can be formed by a mechanism in which the cohesin complex pulls DNA strands through its ring structure using biased Brownian motion.

A structure-based model of the chromosomal cohesin complex, accompanied by molecular-mechanistic simulations, explains cohesin's key role in topologically entrapping DNA, as well as its ability to alternatively extrude DNA loops.

HOXA9 is a transcriptional maintenance factor for anti-apoptotic genes that accelerate MYC-driven leukemia.

Single-molecule methods reveal that cytidine triphosphate promotes DNA condensation specifically at bacterial centromeres by facilitating one-dimensional diffusion of ParB from parS sites.

DNA lesions formed by alkylating agents trigger double-strand breaks, in the absence of replication, by the action of MMR and BER at nearby O-alkyl and N-alkyl adducts, respectively.

Genetic and physical analyses reveal that DNA-RNA hybrids form fortuitously at DNA double-strand breaks during transcription and need removal to allow repair by homologous recombination.

Topoisomerase 2α DNA breaks induced by G-quadruplex ligands are associated with a topological stress resulting from a transcription-dependent mechanism and counteracted by DNA topoisomerase 1 and factors promoting transcription elongation.
