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

Several techniques are available to study chromosomes or chromosomal domains in nuclei of chemically fixed or living cells. Current methods to detect DNA sequences in vivo are limited to trans interactions between a DNA sequence and a transcription factor from natural systems. Here, we expand live cell imaging tools using a novel approach based on zinc finger-DNA recognition codes. We constructed several polydactyl zinc finger (PZF) DNA-binding domains aimed to recognize specific DNA sequences in Arabidopsis and mouse and fused these with GFP. Plants and mouse cells expressing PZF:GFP proteins were subsequently analyzed by confocal microscopy. For Arabidopsis, we designed a PZF:GFP protein aimed to specifically recognize a 9-bp sequence within centromeric 180-bp repeat and monitored centromeres in living roots. Similarly, in mouse cells a PZF:GFP protein was targeted to a 9-bp sequence in the major satellite repeat. Both PZF:GFP proteins localized in chromocenters which represent heterochromatin domains containing centromere and other tandem repeats. The number of PZF:GFP molecules per centromere in Arabidopsis, quantified with near single-molecule precision, approximated the number of expected binding sites. Our data demonstrate that live cell imaging of specific DNA sequences can be achieved with artificial zinc finger proteins in different organisms.
