Mitotic DNA repair by TMEJ suppresses replication stress-induced nuclear envelope reassembly defect.
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 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
Replication stress (RS), if not effectively and timely addressed, could result in DNA damage in mitosis. However, the relationship between RS and other mitotic events, such as nuclear envelope (NE) breakdown and reassembly, remains poorly understood. Here we report that RS can lead to NE defect. Importantly, rather than de novo NE rupture, the defect per se is a result of nuclear envelope reassembly defect (NERD) during mitosis. Interestingly, NERD is associated with mitotic DNA damage, and repair of the damage by DNA polymerase theta (Polθ)-mediated end joining (TMEJ) ameliorates NERD. Genomic mapping of lamina associated domains (LADs) by cleavage under targets and tagmentation (CUT&Tag) identifies a population of replication stress-sensitive LADs (RESSLADs). Strikingly, a substantial portion of RESSLADs reside in the common fragile sites (CFSs). The loss of RESSLADs-NE interaction under RS might be attributed to the sustained phosphorylation of Lamin A/C at the sites of NERD. In addition, prominent NE defect is observed under multiple conditions of synthetic lethality. Altogether, these findings establish a link between genome instability and nuclear vulnerability under replication stress.
