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

Groucho (Gro)/TLE transcriptional corepressors are involved in a variety of developmental mechanisms, including neuronal differentiation. They contain a conserved C-terminal WD40 repeat domain that mediates interactions with several DNA-binding proteins. In particular, Gro/TLE1 interacts with forkhead transcription factor brain factor 1 (BF-1; also termed FoxG1). BF-1 is an essential regulator of neuronal differentiation during cerebral cortex development and represses transcription together with Gro/TLE1. Gro/TLE-related gene product 6 (Grg6) shares with Gro/TLEs a conserved WD40 repeat domain but is more distantly related at its N-terminal half. We demonstrate that Grg6 is expressed in cortical neural progenitor cells and interacts with BF-1. In contrast to Gro/TLE1, however, Grg6 does not promote, but rather suppresses, BF-1-mediated transcriptional repression. Consistent with these observations, Grg6 interferes with the binding of Gro/TLE1 to BF-1 and does not repress transcription when targeted to DNA. Moreover, coexpression of Grg6 and BF-1 in cortical progenitor cells leads to a decrease in the number of proliferating cells and increased neuronal differentiation. Conversely, Grg6 knockdown by RNA interference causes decreased neurogenesis. These results identify a new role for Grg6 in cortical neuron development and establish a functional link between Grg6 and BF-1.
