Phosphorylation-dependent WRN-RPA interaction promotes recovery of stalled forks at secondary DNA structure.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The WRN protein is vital for managing perturbed replication forks. Replication Protein A strongly enhances WRN helicase activity in specific in vitro assays. However, the in vivo significance of RPA binding to WRN has largely remained unexplored. We identify several conserved phosphorylation sites in the acidic domain of WRN targeted by Casein Kinase 2. These phosphorylation sites are crucial for WRN-RPA interaction. Using an unphosphorylable WRN mutant, which lacks the ability to bind RPA, we determine that the WRN-RPA complex plays a critical role in fork recovery after replication stress countering the persistence of G4 structures after fork stalling. However, the interaction between WRN and RPA is not necessary for the processing of replication forks when they collapse. The absence of WRN-RPA binding hampers fork recovery, causing single-strand DNA gaps, enlarged by MRE11, and triggering MUS81-dependent double-strand breaks, which require repair by RAD51 to prevent excessive DNA damage.
