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

Yeast telomeres reversibly repress the transcription of adjacent genes, a phenomenon called telomere position effect (TPE). TPE is thought to result from Rap1 and Sir protein-mediated spreading of heterochromatin-like structures from the telomeric DNA inwards. Because Rap1p is associated with subtelomeric chromatin as well as with telomeric DNA, yeast telomeres are proposed to form fold-back or looped structures. TPE can be eliminated in trans by deleting SIR genes or in cis by transcribing through the C(1-3)A/TG(1-3) tract of a telomere. We show that the promoter of a telomere-linked URA3 gene was inaccessible to restriction enzymes and that accessibility increased both in a sir3 strain and upon telomere transcription. We also show that subtelomeric chromatin was hypoacetylated at histone H3 and at each of the four acetylatable lysines in histone H4 and that histone acetylation increased both in a sir3 strain and when the telomere was transcribed. When transcription through the telomeric tract occurred in G(1)-arrested cells, TPE was lost, demonstrating that activation of a silenced telomeric gene can occur in the absence of DNA replication. The loss of TPE that accompanied telomere transcription resulted in the rapid and efficient loss of subtelomeric Rap1p. We propose that telomere transcription disrupts core heterochromatin by eliminating Rap1p-mediated telomere looping. This interpretation suggests that telomere looping is critical for maintaining TPE.
