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

In Tetrahymena, as in other ciliates, development of the somatic macronucleus during conjugation involves extensive and reproducible rearrangements of the germ line genome, including chromosome fragmentation and excision of internal eliminated sequences (IESs). The molecular mechanisms controlling these events are poorly understood. To investigate the role that histone acetylation may play in the regulation of these processes, we treated Tetrahymena cells during conjugation with the histone deacetylase inhibitor trichostatin A (TSA). We show that TSA treatment induces developmental arrests in the early stages of conjugation but does not significantly affect the progression of conjugation once the mitotic divisions of the zygotic nucleus have occurred. Progeny produced from TSA-treated cells were examined for effects on IES excision and chromosome breakage. We found that TSA treatment caused partial inhibition of excision of five out of the six IESs analyzed but did not affect chromosome breakage at four different sites. TSA treatment greatly delayed in some cells and inhibited in most the excision events in the developing macronucleus. It also led to loss of the specialized subnuclear localization of the chromodomain protein Pdd1p that is normally associated with DNA elimination. We propose a model in which underacetylated nucleosomes mark germ line-limited sequences for excision.
