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

We have identified a novel brain-derived single-stranded-DNA-binding protein that interacts with a region of the human neurotropic JC virus enhancer designated the lytic control element (LCE). This nuclear factor, LCP-1 (for lytic control element-binding protein 1), specifically recognizes the LCE, as determined by gel retardation assays. Alkylation interference showed that specific nucleotides within the LCE were contacted by LCP-1. Subsequent experiments revealed that point mutations within the LCE differentially affected LCP-1 binding. UV cross-linking and competition analysis suggested that the LCP-1 DNA-protein complexes were 50 to 52 and 100 to 120 kDa in size. Promoter mutations that affected LCP-1 binding reduced early mRNA transcription during the early phase of the lytic cycle. However, upon DNA replication in the presence of JC virus T antigen, when early mRNA initiation shifts to new locations indicative of the late phase, the LCP-1 mutations had no effect. We suggest that the JC virus early transcription unit is differentially regulated by LCP-1 prior to but not after DNA replication, suggesting a novel mechanism by which DNA structure regulates eukaryotic gene expression.
