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

RecQ helicases are required for the maintenance of genome stability. Characterization of the substrate specificity and identification of the binding partners of the five human RecQ helicases are essential for understanding their function. In the present study, we have developed an efficient baculovirus expression system that allows us to obtain milligram quantities of recombinant RECQ1. Our gel filtration and dynamic light scattering experiments show that RECQ1 has an apparent molecular mass of 158 kDa and a hydrodynamic radius of 5.4 +/- 0.6 nm, suggesting that RECQ1 forms dimers in solution. The oligomeric state of RECQ1 remains unchanged upon binding to a single-stranded (ss)DNA fragment of 50 nt. We show that RECQ1 alone is able to unwind short DNA duplexes (<110 bp), whereas considerably longer substrates (501 bp) can be unwound only in the presence of human replication protein A (hRPA). The same experiments with Escherichia coli SSB show that RECQ1 is specifically stimulated by hRPA. However, hRPA does not affect the ssDNA-dependent ATPase activity of RECQ1. In addition, our far western, ELISA and co-immunoprecipitation experiments demonstrate that RECQ1 physically interacts with the 70 kDa subunit of hRPA and that this interaction is not mediated by DNA.
