PARP1 Activation Controls Stress Granule Assembly after Oxidative Stress and DNA Damage.
Article in Cells, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
DNA damage causes PARP1 activation in the nucleus to set up the machinery responsible for the DNA damage response. Here, we report that, in contrast to cytoplasmic PARPs, the synthesis of poly(ADP-ribose) by PARP1 opposes the formation of cytoplasmic mRNA-rich granules after arsenite exposure by reducing polysome dissociation. However, when mRNA-rich granules are pre-formed, whether in the cytoplasm or nucleus, PARP1 activation positively regulates their assembly, though without additional recruitment of poly(ADP-ribose) in stress granules. In addition, PARP1 promotes the formation of TDP-43- and FUS-rich granules in the cytoplasm, two RNA-binding proteins which form neuronal cytoplasmic inclusions observed in certain neurodegenerative diseases such as amyotrophic lateral sclerosis and frontotemporal lobar degeneration. Together, the results therefore reveal a dual role of PARP1 activation which, on the one hand, prevents the early stage of stress granule assembly and, on the other hand, enables the persistence of cytoplasmic mRNA-rich granules in cells which may be detrimental in aging neurons.
