Genetic, cellular, and molecular analyses reveal that the reduced abundance of total nascent transcripts that occurs after irradiation is largely due to the repression of histone and rRNA encoding genes.

A family of RNA binding proteins that diverged 200 million years ago have parallel roles in protecting the transcriptomic integrity of ultra-long exons within their respective cell types.
Many well-studied maternal developmental pathways that are required for embryonic development in Drosophila are regulated by the transcription factor OVO in the Drosophila female germline.
To maintain genomic integrity during oocyte development, the tumor suppressor BRCA1/BRC-1 and the SMC-5/6 complex both repress intersister crossover recombination events while BRCA1/BRC-1 also specifically inhibits error prone repair of DNA breaks during meiotic prophase I.
