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

Peripheral nuclear localization of chromosomal loci correlates with late replication in yeast and metazoan cells. To test whether peripheral positioning can impose late replication, we examined whether artificial tethering of an early-initiating replication origin to the nuclear periphery delays its replication in budding yeast. We tested the effects of three different peripheral tethering constructs on the time of replication of the early replication origin ARS607. Using the dense-isotope transfer method to assess replication time, we found that ARS607 still replicates early when tethered to the nuclear periphery using the Yif1 protein or a fragment of Sir4, whereas tethering using a Yku80 construct produces only a very slight replication delay. Single-cell microscopic analysis revealed no correlation between peripheral positioning of ARS607 in individual cells and delayed replication. Overall, our results demonstrate that a replication origin can initiate replication early in S phase, even if artificially relocated to the nuclear periphery.
