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 telomerase reverse transcriptase hTERT is highly expressed in undifferentiated embryonic cells and silenced in the majority of somatic cells. To investigate the mechanisms of hTERT silencing, we have developed a novel reporter using a bacterial artificial chromosome (BAC) that contained the entire hTERT gene and its neighboring loci, hCRR9 and hXtrp2. Firefly and Renilla luciferases were used to monitor transcription from the hTERT and hCRR9 promoters, respectively. In mouse embryonic stem cells stably integrated with the BAC reporter, both hTERT and hCRR9 promoters were highly expressed. Upon differentiation into embryoid bodies and further into mineral-producing osteogenic cells, the hTERT promoter activity decreased progressively, whereas the hCRR9 promoter remained highly active, both resembling their endogenous counterparts. In fully differentiated cells, the hTERT promoter was completely silenced and adopted a chromatin structure that was similar to its native counterpart in human cells. Inhibition of histone deacetylases led to the opening of the hTERT promoter and partially relieved repression, suggesting that histone deacetylation was necessary but not sufficient for hTERT silencing. Thus, our result demonstrated that developmental silencing of the human TERT locus could be recapitulated in a chromosomal position-independent manner during the differentiation of mouse embryonic stem cells.
