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 major late 16S mRNA species of simian virus 40 encodes both a 61-amino-acid protein, LP1, and the major virion protein, VP1. Although the initiation signal GCCAUGG is usually utilized at high efficiency, at least one-third of 40S ribosomal subunits bypass it when it is present on the major 16S mRNA of simian virus 40 (S. A. Sedman, P. J. Good, and J. E. Mertz, J. Virol. 63:3884-3893, 1989). The LP1 translation initiation codon is situated 10 bases from the 5' end of this mRNA. To determine whether the short length of the untranslated leader of this mRNA affects the efficiency of translation initiation at the LP1 initiation signal, monkey cells were transfected with plasmids which encode major late 16S-like mRNAs with 5' untranslated regions (UTRs) of 6 or 44 bases. Decreasing the length of the 5' UTR from 44 to 6 bases resulted in a 30% decrease in translation initiation at the LP1 AUG and a threefold increase in synthesis of VP1. When the VP1 open reading frame was replaced with the chloramphenicol acetyltransferase open reading frame, the reduction in 5' UTR length resulted in a 70% decrease in translation initiation at the LP1 AUG and a 30% increase in chloramphenicol acetyltransferase synthesis. Therefore, ribosomes bypass an AUG codon more efficiently when it is located very close to the 5' end of the mRNA.
