Evidence is provided suggesting that heterochromatin re-organisation during cell senescence can compromise the structural integrity of the nucleus, leading to activation of an inflammatory process.
Mutagenizing sequences enriched with promoter motifs creates gene expression de novo, and helps to understand promoter logic, regulatory evolution, and the birth of de novo genes.
N‑terminus of MSL1 protein, involved in dosage compensation in Drosophila, is required for the interaction with non-coding roX2 RNA and the assembly of the complex on the male X chromosome.
