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 investigated the formation of prespliceosomal complex A in HeLa nuclear extracts on a splicing substrate containing an AT-AC (U12-type) intron from the P120 gene. Using an RNase H protection assay and specific blocking oligonucleotides, we find that recognition of the 5' splice-site (5'ss) and branchpoint sequence (BPS) elements by U11 and U12 snRNPs, respectively, displays strong cooperativity, requiring both sites in the pre-mRNA substrate for efficient complex formation. Deletion analysis indicates that beside the 5'ss and BPS, no additional elements in the pre-mRNA are necessary for A-complex formation, although 5' exon sequences provide stimulation. Cross-linking studies with pre-mRNAs containing the 5'ss or BPS alone indicate that recognition of the BPS by the U12 snRNP is stimulated at least 20- to 30-fold by the binding of the U11 snRNP to the 5'ss in the same pre-mRNA molecule, whereas recognition of the 5'ss by U11 is stimulated approximately fivefold by the U12/BPS interaction. These results argue that intron recognition in the U12-dependent splicing pathway is carried out by a single U11/U12 di-snRNP complex, suggesting greater rigidity in the intron recognition process than in the major spliceosome.
