Translesion-synthesis-mediated bypass of DNA lesions occurs predominantly behind replication forks restarted by PrimPol.
Article in Cell reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 bypass of DNA lesions by translesion synthesis (TLS) polymerases is a critical step for DNA damage tolerance, allowing the completion of DNA synthesis. It has been under debate whether TLS-mediated bypass restarts stalled forks or occurs post-replicationally. We developed cell imaging techniques based on proximity ligation to monitor the recruitment of TLS polymerases Polκ and Polη to DNA adducts. We show that this recruitment is adduct specific, with Polκ being preferentially recruited to benzo[a]pyrene diol epoxide (BPDE) lesions and Polη to cisplatin lesions. The recruitment depends on the primase-polymerase PrimPol, which reprimes downstream of stalled forks to restart DNA synthesis. TLS polymerase deficiency results in the accumulation of single-stranded DNA (ssDNA) gaps in an adduct-specific manner, which are processed into double-strand breaks (DSBs). Our findings argue that TLS occurs mainly behind the restarted replication fork in order to fill PrimPol-derived gaps and is essential to suppress the nucleolytic conversion of ssDNA gaps into cytotoxic DSBs in a lesion-specific manner.
