1 · What the graph read from it

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.

2 · The registry

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

Microtubules and nuclear transmembrane SUN1/2 proteins promote the mobility of DNA Double Strand Breaks (DSBs) induced by ionizing radiation and the misrepair of one-ended DSBs induced in BRCA1-deficient cells by Poly(ADP-ribose) polymerase inhibitors (PARPi). However, whether microtubules promote aberrant DSBs repair by altering the nuclear structure and whether the nuclear structure itself plays a role in these processes is still unclear. Here we show that microtubule-dependent DSBs mobility in BRCA1-deficient cells after PARPi treatment is associated with nuclear envelope (NE) invaginations. Furthermore, increasing NE invaginations by Lmna deletion or inhibition of sphingolipid synthesis increases DSBs mobility, chromosomal aberrations, and PARPi cytotoxicity in BRCA1-deficient cells. These findings reveal a functional connection between the NE and DSB repair and suggest that drugs increasing NE deformability will enhance PARPi therapy efficacy in BRCA1-deficient cancers.
