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

The membrane-type matrix metalloproteinases (MT-MMPs) are essential for pericellular matrix remodeling in late stages of development, as well as in growth and tissue homeostasis in postnatal life. Although early morphogenesis is perceived to involve substantial tissue remodeling, the roles of MT-MMPs in these processes are only partially characterized. Here we explore the functions of 2 prominently expressed MT-MMPs, MT1-MMP and MT2-MMP, and describe their roles in the process of placental morphogenesis. The fetal portion of the placenta, in particular the labyrinth (LA), displays strong overlapping expression of MT1-MMP and MT2-MMP, which is critical for syncytiotrophoblast formation and in turn for fetal vessels. Disruption of trophoblast syncytium formation consequently leads to developmental arrest with only a few poorly branched fetal vessels entering the LA causing embryonic death at embryonic day 11.5. Through knockdown of MMP expression, we demonstrate that either MT1-MMP or MT2-MMP is crucial specifically during development of the LA. In contrast, knockdown of MT-MMP activity after LA formation is compatible with development to term and postnatal life. Taken together these data identify essential but interchangeable roles for MT1-MMP or MT2-MMP in placental vasculogenesis and provide the first example of selective temporal and spatial MMP activity required for development of the mouse embryo.
