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

The genomes of hyperthermophilic Archaea encode dozens of methylation guide, C/D box small RNAs that guide 2'-O-methylation of ribose to specific sites in rRNA and various tRNAs. The genes encoding the Sulfolobus homologues of eukaryotic proteins that are known to be present in C/D box small nucleolar ribonucleoprotein (snoRNP) complexes were cloned, and the proteins (aFIB, aNOP56, and aL7a) were expressed and purified. The purified proteins along with an in vitro transcript of the Sulfolobus sR1 small RNA were reconstituted in vitro, into an RNP complex. The order of assembly of the three proteins onto the RNA was aL7a, aNOP56, and aFIB. The complex was active in targeting S-adenosyl methionine (SAM)-dependent, site-specific 2'-O-methylation of ribose to a short fragment of ribosomal RNA (rRNA) that was complementary to the D box guide region of the sR1 small RNA. The presence of aFIB was essential for methylation; mutant proteins having amino acid replacements in the SAM-binding motif of aFIB were able to assemble into an RNP complex, but the resulting complexes were defective in methylation activity. These experiments define the minimal number of components and the conditions required to achieve in vitro RNA guide-directed 2'-O-methylation of ribose in a target RNA.
