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

Lamin filaments are major components of the nucleoskeleton that bind LINC complexes and many nuclear membrane proteins. The tail domain of lamin A directly binds 21 known partners, including actin, emerin, and SREBP1, but how these interactions are regulated is unknown. We report small ubiquitin-like modifier 1 (SUMO1) as a major new posttranslational modification of the lamin A tail. Two SUMO1 modification sites were identified based on in vitro SUMOylation assays and studies of Cos-7 cells. One site (K420) matches the SUMO1 target consensus; the other (K486) does not. On the basis of the position of K486 on the lamin A Ig-fold, we hypothesize the SUMO1 E2 enzyme recognizes a folded structure-dependent motif that includes residues genetically linked to familial partial lipodystrophy (FPLD). Supporting this model, SUMO1-modification of the lamin A tail is reduced by two FPLD-causing mutations, G465D and K486N, and by single mutations in acidic residues E460 and D461. These results suggest a novel mode of functional control over lamin A in cells.
