Abstract
Over the past few decades, unbiased approaches such as genetic screening and protein affinity purification have unveiled numerous proteins involved in DNA double-strand break (DSB) repair and maintaining genome stability. However, despite our knowledge of these protein factors, the underlying molecular mechanisms governing key cellular events during DSB repair remain elusive. Recent evidence has shed light on the role of non-protein factors, such as RNA, in several pivotal steps of DSB repair. In this review, we provide a comprehensive summary of these recent findings, highlighting the significance of ribosomal RNA (rRNA) as a critical mediator of DNA damage response, meiosis, and mitosis. Moreover, we discuss potential mechanisms through which rRNA may influence genome integrity.
期刊介绍：
DNA Repair provides a forum for the comprehensive coverage of DNA repair and cellular responses to DNA damage. The journal publishes original observations on genetic, cellular, biochemical, structural and molecular aspects of DNA repair, mutagenesis, cell cycle regulation, apoptosis and other biological responses in cells exposed to genomic insult, as well as their relationship to human disease.
DNA Repair publishes full-length research articles, brief reports on research, and reviews. The journal welcomes articles describing databases, methods and new technologies supporting research on DNA repair and responses to DNA damage. Letters to the Editor, hot topics and classics in DNA repair, historical reflections, book reviews and meeting reports also will be considered for publication.
