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

Type IV collagen is a major component of the basement membrane and interacts with numerous other basement membrane proteins. Many of these interactions are poorly characterized. Type IV collagen is abundantly post-translationally modified with 3-hydroxyproline (3-Hyp), but 3-Hyp's biochemical role in type IV collagen's interactions with other proteins is not well established. In this work, we present binding data consistent with a major role of 3-Hyp in interactions of collagen IV with glycoprotein VI and nidogens 1 and 2. The increased binding interaction between type IV collagen without 3-Hyp and glycoprotein VI has been the subject of some controversy, which we sought to explore, whereas the lack of binding of nidogens to type IV collagen without 3-Hyp is novel. Using tandem MS, we show that the putative glycoprotein VI-binding site is 3-Hyp-modified in WT PFHR-9 type IV collagen, but not in PFHR-9 cells in which prolyl-3-hydroxylase 2 (P3H2) has been knocked out (KO). Moreover, we observed altered 3-Hyp occupancy across many other sites. Using amino acid analysis of type IV collagen from the WT and P3H2 KO cell lines, we confirm that P3H2 is the major, but not the only 3-Hyp-modifying enzyme of type IV collagen. These findings underscore the importance of post-translational modifications of type IV collagen for interactions with other proteins.
