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

By adopting a monoclonal antibody approach, we have identified a novel splicing factor of 35 kDa which we have termed 9G8. The isolation and characterization of cDNA clones indicate that 9G8 is a novel member of the serine/arginine (SR) splicing factor family because it includes an N-terminal RNA binding domain (RBD) and a C-terminal SR domain. The RNA binding domain of 9G8 is highly homologous to those of the SRp20 and RBP1 factors (79-71% identity), but the homology is less pronounced in the cases of SF2/ASF and SC35/PR264 (45-37% identity). Compared with the other SR splicing factors, 9G8 presents some specific sequence features because it contains an RRSRSXSX consensus sequence repeated six times in the SR domain, and a CCHC motif in its median region, similar to the zinc knuckle found in the SLU7 splicing factor in yeast. Complete immunodepletion of 9G8 from a nuclear extract, which is accompanied by a substantial depletion of other SR factors, results in a loss of splicing activity. We show that a recombinant 9G8 protein, expressed using a baculovirus vector and excluding other SR factors, rescues the splicing activity of a 9G8-depleted nuclear extract and an S100 cytoplasmic fraction. This indicates that 9G8 plays a crucial role in splicing, similar to that of the other SR splicing factors. This similarity was confirmed by the fact that purified human SC35 also rescues the 9G8-depleted extract. The identification of the 9G8 factor enlarges the essential family of SR splicing factors, whose members have also been proposed to play key roles in alternative splicing.
