Project description:Safeguarding replication fork stability in transcriptionally active regions, which require high DNA replication accuracy, is crucial for precise DNA replication and prevention of mutations. However, how cells ensure the stability of replication forks in these regions remains a critical challenge. Here, we discovered the pervasive existence of replication forks-associated RNA-DNA hybrids (RF-RDs) within transcriptionally active regions, where they act as a protective barrier against DNA2-mediated nascent DNA degradation and prevent replication fork collapse upon replication stress. Subsequently, the RNA helicase DDX39A dismantles RF-RDs, facilitating proper DNA2-mediated DNA resection and replication fork restart. Excessive dissolution of RF-RDs causes replication fork collapse and genomic instability, while insufficient dissolution of RF-RDs under replication stress increases fork stability, resulting in chemoresistance that can be reversed by eliminating RF-RDs. In summary, we elucidated the prevalence of RF-RDs at replication forks within transcriptionally active regions, revealed their pivotal role in safeguarding replication fork stability, and proposed that targeting RF-RDs holds promise for augmenting chemotherapeutic efficacy.

Project description:Renal fibrosis (RF) is the common pathological outcome and central treatment target of multiple chronic kidney diseases. Currently, the molecular mechanisms of RF remain poorly understood. Therefore, this study aimed to established the adenine- and UUO-induced rat models, identified differentially expressed genes in their renal tissues using RNA-Seq analysis, and screened RF-related hub targets and key pathways.
