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

Mechanisms governing the transcription of p16(INK4a), one of the master regulators of cellular senescence, have been extensively studied. However, little is known about chromatin dynamics taking place at its promoter and distal enhancer. Here, we report that Forkhead box A1 protein (FOXA1) is significantly upregulated in both replicative and oncogene-induced senescence, and in turn activates transcription of p16(INK4a) through multiple mechanisms. In addition to acting as a classic sequence-specific transcriptional activator, FOXA1 binding leads to a decrease in nucleosome density at the p16(INK4a) promoter in senescent fibroblasts. Moreover, FOXA1, itself a direct target of Polycomb-mediated repression, antagonizes Polycomb function at the p16(INK4a) locus. Finally, a systematic survey of putative FOXA1 binding sites in the p16(INK4a) genomic region revealed an ∼150 kb distal element that could loop back to the promoter and potentiate p16(INK4a) expression. Overall, our findings establish several mechanisms by which FOXA1 controls p16(INK4a) expression during cellular senescence.
