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 human negative elongation factor (NELF) is a four-subunit protein complex that inhibits the movement of RNA polymerase II (RNAPII) at an early elongation stage in vitro. NELF-mediated stalling of RNAPII also attenuates transcription of a number of inducible genes in human cells. To obtain a genome-wide understanding of human NELF-mediated transcriptional regulation in vivo, we carried out an exon array study in T47D breast cancer cells with transient small interfering RNA knockdown of individual NELF subunits. Upon depletion of NELF-A, -C, or -E, the vast majority of NELF-regulated genes were down-regulated. Many of the down-regulated genes encode proteins that play key roles in cell cycle progression. Consequently, NELF knockdown resulted in significant reduction in DNA synthesis and cell proliferation. Chromatin immunoprecipitation showed that NELF knockdown led to dissociation of RNAPII from the promoter-proximal region of the cell cycle-regulating genes. This was accompanied by decreased histone modifications associated with active transcription initiation (H3K9Ac) and elongation (H3K36Me3), as well as reduced recruitment of the general transcription factor TFIIB and increased overall histone occupancy at a subset of the down-regulated promoters. Lastly, our study indicates that NELF regulates alternative transcription initiation of BSG (Basigin) gene by differentially influencing RNAPII density at the two neighboring exons at the 5' end of the gene. Taken together, our data suggest a diverse transcriptional consequence of NELF-mediated RNAPII pausing in the human genome.
