Nuclear FKBPs, Fpr3 and Fpr4 affect genome-wide genes transcription.

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.
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
Fpr3 and Fpr4 of Saccharomyces cerevisiae are nuclear FK506-binding proteins each containing an extended acidic domain in addition to the conserved FK506-binding/peptidylprolyl isomerase (PPIase) domain. Previous studies have shown that the PPIase domain regulates histone H3 methylation, while the acidic domain facilitates histone deposition and may regulate rDNA silencing. To gain insight into the role of FKBPs in maintaining chromatin structure, we examined the transcriptional profiles of fpr3 (-) and fpr4 (-) cells. Our results show that both proteins modulate the expression of a large number of genes randomly distributed throughout the genome, a pattern resembling those observed with yeast cells lacking other histone chaperones such as CAF1 and Asf1. Significant overlaps are found between nuclear FKBPs-modulated and the Asf1/CAF1-modulated genes. Thus, nuclear FKBPs appear to impact chromatin structure like other histone chaperones. Our analyses show that depleting Fpr4 causes no detectable chromatin structural change at the rDNA locus nor de-repression of transcription silencing at the locus, in contrast to a previous report. Furthermore, we demonstrate PPIase domain of the proteins represses transcription when tethered to the promoter of a reporter gene, suggesting that the PPIase domains can act on non-histone chromatin components, when brought to close proximity. The results thus provide a further demonstration for the elusive role of Fpr3 and Fpr4 in histone chaperones.
