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

Basement membranes (BMs) are specialized extracellular matrices (ECMs) essential for tissue structure and function. In non-vertebrates, ECM components can be produced both locally and by distant tissues. In contrast, mammalian ECM has traditionally been considered to originate predominantly from adjacent or tissue-resident cells. The kidney glomerular basement membrane (GBM), composed of laminin-α5β2γ1 and collagen-α3α4α5(IV), is produced by neighboring cells and functions as a filtration barrier. Alport syndrome, a genetic kidney disease, is characterized by GBM structural defects and ectopic laminin-α2 deposition, but the source of this laminin remains unknown. Here, using CRISPR-Cas9 transgenic models, we demonstrated that ectopic laminin-α2 in GBM originates not from local kidney cells but from the circulation. Furthermore, laminin-α2 in the mesangium partially derives from circulating sources even under healthy conditions. Our findings uncover a non-cell-autonomous mechanism whereby GBM integrity regulates circulating protein incorporation, revealing a trans-tissue regulation of BM composition in mammals.
