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

Deregulated Wnt/β-catenin signaling promotes colorectal cancer (CRC) by activating expression of the c-MYC proto-oncogene (MYC). In the nucleus, the β-catenin transcriptional co-activator binds T-cell factor (TCF) transcription factors, and together TCF/β-catenin complexes activate MYC expression through Wnt responsive DNA regulatory elements (WREs). The MYC 3' WRE maps 1.4-kb downstream from the MYC transcription stop site and binds TCF4/β-catenin transcription complexes to activate MYC. However, the underlying mechanisms for how this element operates are not fully understood. Here, we report that the TCF family member, TCF3, plays an important role in regulating MYC expression in CRCs. We demonstrate that TCF3 binds the MYC 3' WRE to repress MYC. When TCF3 is depleted using shRNAs, the MYC 3' WRE is more available to bind TCF4/β-catenin complexes. Stimulating downstream Wnt/β-catenin signaling by inhibiting GSK3β causes an exchange of TCF3 with TCF4/β-catenin complexes to activate MYC. Finally, this transcription factor switch at the MYC 3' WRE controls MYC expression as quiescent cells re-enter the cell cycle and progress to S phase. These results indicate that a dynamic interplay of TCF transcription factors governs MYC gene expression in CRCs.
