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

In Leishmania tarentolae, all mitochondrial tRNAs are encoded in the nuclear genome and imported from the cytosol. It is known that tRNA(Glu)(UUC) and tRNA(Gln)(UUG) are localized in both cytosol and mitochondria. We investigated structural differences between affinity-isolated cytosolic (cy) and mitochondrial (mt) tRNAs for glutamate and glutamine by mass spectrometry. A unique modification difference in both tRNAs was identified at the anticodon wobble position: cy tRNAs have 5-methoxycarbonylmethyl-2- thiouridine (mcm(5)s(2)U), whereas mt tRNAs have 5- methoxycarbonylmethyl-2'-O-methyluridine (mcm(5)Um). In addition, a trace portion (4%) of cy tRNAs was found to have 5-methoxycarbonylmethyluridine (mcm(5)U) at its wobble position, which could represent a common modification intermediate for both modified uridines in cy and mt tRNAs. We also isolated a trace amount of mitochondria-specific tRNA(Lys)(UUU) from the cytosol and found mcm(5)U at its wobble position, while its mitochondrial counterpart has mcm(5)Um. Mt tRNA(Lys) and in vitro transcribed tRNA(Glu) were imported much more efficiently into isolated mitochondria than the native cy tRNA(Glu) in an in vitro importation experiment, indicating that cytosol-specific 2-thiolation could play an inhibitory role in tRNA import into mitochondria.
