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 mitochondrial genome of trypanosomes is composed of ∼50 maxicircles and thousands of minicircles. Maxi-(∼25 kb) and mini-(∼1 kb)circles are catenated and packed into a dense structure called a kinetoplast. Both types of circular DNA are transcribed by a phage-like RNA polymerase: maxicircles yield multicistronic rRNA and mRNA precursors, while guide RNA (gRNA) precursors are produced from minicircles. To function in mitochondrial translation, pre-mRNAs must undergo a nucleolytic processing and 3' modifications, and often uridine insertion/deletion editing. gRNAs, which represent short (50-60 nt) RNAs directing editing reactions, are produced by 3' nucleolytic processing of a much longer precursor followed by 3' uridylation. Ribosomal RNAs are excised from precursors and their 3' ends are also trimmed and uridylated. All tRNAs are imported from the cytoplasm and some are further modified and edited in the mitochondrial matrix. Historically, the fascinating phenomenon of RNA editing has been extensively studied as an isolated pathway in which nuclear-encoded proteins mediate interactions of maxi- and minicircle transcripts to create open reading frames. However, recent studies unraveled a highly integrated network of mitochondrial genome expression including critical pre- and post-editing 3' mRNA processing, and gRNA and rRNA maturation steps. Here we focus on RNA 3' adenylation and uridylation as processes essential for biogenesis, stability and functioning of mitochondrial RNAs.
