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

Cell cycle progression in mammalian cells from G(1) into S phase requires sensing and integration of multiple inputs, in order to determine whether to continue to cellular DNA replication and subsequently, to cell division. Passage to S requires transition through the restriction point, which at a molecular level consists of a bistable switch involving E2Fs and pRb family members. At the G(1)/S boundary, a number of genes essential for DNA replication and cell cycle progression are upregulated, promoting entry into S phase. Although the activating E2Fs are the most extensively characterized transcription factors driving G(1)/S expression, LSF is also a transcription factor essential for stimulating G(1)/S gene expression. A critical LSF target gene at this stage, Tyms, encodes thymidylate synthetase. In investigating how LSF is activated in a cell cycle-dependent manner, we recently identified a novel time delay mechanism for regulating its activity during G(1) progression, which is apparently independent of the E2F/pRb axis. This involves inhibition of LSF in early G(1) by two major proliferative signaling pathways: ERK and cyclin C/CDK, followed by gradual dephosphorylation during mid- to late-G(1). Whether LSF and E2F act independently or in concert to promote G(1)/S progression remains to be determined.
