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

Alport syndrome (AS) is a hereditary disease caused by mutations in the COL4A5 gene and leads to chronic kidney disease. Currently, no specific treatment has been developed. However, a recent study using AS-model mice demonstrated that the exon skipping method could partially rescue the symptoms. In this study, we evaluated the effects of the exon skipping method using kidney organoids generated from AS-patient-derived induced pluripotent stem cells (AS-iPSCs). We generated kidney organoids from AS-iPSCs, which exhibited nephron structures. As expected, the C-terminus of COL4A5 was not expressed in AS-organoids. Interestingly, anti-sense oligonucleotides restored the expression of the C-terminus of COL4A5 in vitro. Next, we transplanted AS-organoids into mice and evaluated glomerular basement membrane formation in vivo. We found that AS-organoids formed a lower slit diaphragm ratio compared to control organoids. Finally, we assessed the effects of exon skipping on transplanted organoids but observed minimum effects. These studies suggest that AS-iPSCs can generate kidney organoids lacking the C-terminus of COL4A5, and that exon skipping can induce its expression in vitro.
