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

XPB helicase is the largest subunit of transcription factor IIH (TFIIH), a ten-subunit protein complex essential for transcription initiation and nucleotide excision repair (NER) in Eukarya. Two XPB homologues (XPBI and XPBII) are present in the genome of most crenarchaeota, one of the two major phyla of archaea; however, the biochemical properties have not been fully characterized and their cellular roles have not been clearly defined. Here, we report that XPBI from the hyperthermophilic crenarchaeon Sulfolobus tokodaii (StoXPBI) is able to destabilize double-stranded DNA (dsDNA) helix independent of ATP (designated as dsDNA melting activity). This activity is inhibited by single-stranded DNA (ssDNA) and relies on the unique N-terminal domain of StoXPBI, which is also likely responsible for the intrinsic strong ssDNA binding activity of StoXPBI as revealed by deletion analysis. We demonstrate that the ATPase activity of StoXPBII is remarkably stimulated by StoBax1, a nuclease partner of StoXPBII. The role of the unique dsDNA melting activity of XPBI in NER in archaea was discussed.
