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 A is formed from prelamin A by four post-translational processing steps-farnesylation, release of the last three amino acids of the protein, methylation of the farnesylcysteine and the endoproteolytic release of the C-terminal 15 amino acids (including the farnesylcysteine methyl ester). When the final processing step does not occur, a farnesylated and methylated prelamin A accumulates in cells, causing a severe progeroid disease, restrictive dermopathy (RD). Whether RD is caused by the retention of farnesyl lipid on prelamin A, or by the retention of the last 15 amino acids of the protein, is unknown. To address this issue, we created knock-in mice harboring a mutant Lmna allele (LmnanPLAO) that yields exclusively non-farnesylated prelamin A (and no lamin C). These mice had no evidence of progeria but succumbed to cardiomyopathy. We suspected that the non-farnesylated prelamin A in the tissues of these mice would be strikingly mislocalized to the nucleoplasm, but this was not the case; most was at the nuclear rim (indistinguishable from the lamin A in wild-type mice). The cardiomyopathy could not be ascribed to an absence of lamin C because mice expressing an otherwise identical knock-in allele yielding only wild-type prelamin A appeared normal. We conclude that lamin C synthesis is dispensable in mice and that the failure to convert prelamin A to mature lamin A causes cardiomyopathy (at least in the absence of lamin C). The latter finding is potentially relevant to the long-term use of protein farnesyltransferase inhibitors, which lead to an accumulation of non-farnesylated prelamin A.
