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

Through the use of various non-equilibrium RNA binding techniques, the C protein tetramer of mammalian40S hnRNP particles has been characterized previously as a poly(U) binding protein with specificity for the pyrimidine-rich sequences that often precede 3' intron-exon junctions. C protein has also been characterized as a sequence-independent RNA chaperonin that is distributed along nascent transcripts through cooperative binding and as a protein ruler that defines the length of RNA packaged in 40S monoparticles. In this study fluorescence spectroscopy was used to monitor C protein-oligonucleotide binding in a competition binding assay under equilibrium conditions. Twenty nucleotide substrates corresponding to polypyrimidine tracts from IVS1 of the adenovirus-2 major late transcript, the adenovirus-2 oncoprotein E1A 3' splice site, IVS2 of human alpha-tropomyosin, the consensus polypyrimidine tract for U2AF65, AUUUA repeats and r(U)20were used as competitors. A 20 nt beta-globin intronic sequence and a randomly generated oligo were used as competitor controls. These studies reveal that native C protein possesses no enhanced affinity for uridine-rich oligonucleotides, but they confirm the enhanced affinity of C protein for an oligonucleotide identified as a high affinity substrate through selection and amplification. Evidence that the affinity of C protein for the winner sequence is due primarily to its unique structure or to a unique context is seen in its retained substrate affinity when contiguous uridines are replaced with contiguous guanosines.
