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

Mutations in TRPS1 cause trichorhinophalangeal syndrome types I and III, which are characterized by sparse scalp hair in addition to craniofacial and skeletal abnormalities. Trps1 is a vertebrate transcription factor that contains nine zinc-finger domains, including a GATA-type zinc finger through which it binds DNA. Mice in which the GATA domain of Trps1 has been deleted (Trps1(Δgt/Δgt)) have a reduced number of pelage follicles and lack vibrissae follicles postnatally. To identify the transcriptional targets of Trps1 in the developing vibrissa follicle, we performed microarray hybridization analysis, comparing expression patterns in the whisker pads of wild-type versus Trps1(Δgt/Δgt) embryos. We identified a number of transcription factors and Wnt inhibitors among transcripts downregulated in the mutant embryos and several extracellular matrix proteins that were upregulated in the mutant samples, and demonstrated that target gene expression levels were altered in vivo in Trps1(Δgt/Δgt) vibrissae. Unexpectedly, we discovered that Trps1 can directly bind the promoters of its target genes to activate transcription, expanding upon its established role as a transcriptional repressor. Our findings identify Trps1 as a novel regulator of the Wnt signaling pathway and of early hair follicle progenitors in the developing vibrissa follicle.
