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

Mitochondrial RNA metabolism in Trypanosoma brucei is a complex process involving both extensive RNA editing and control of RNA stability. MRP1/2 and RBP16 are two factors that have been implicated in regulating the editing and stability of specific mRNAs. These two factors exhibit similar nonspecific RNA binding and RNA-annealing activities, suggesting that some of their actions may have been previously masked by functional redundancy. Here, we examine the functional interaction of MRP1/2 and RBP16 by separate and simultaneous RNA interference and by overexpressing RBP16 in an MRP1/2-depleted background. Simultaneous depletion of these factors resulted in synthetic lethality in procyclic trypanosomes. Analysis of mitochondrial RNAs in procyclic cells revealed distinct functions for MRP1/2 and RBP16 toward edited apocytochrome b mRNA, redundant functions in stabilization of edited ATPase subunit 6 and cytochrome oxidase subunit 3 mRNAs, and concentration-dependent positive and negative functions for RBP16 toward edited RPS12 mRNAs. While simultaneous MRP1/2-RBP16 depletion had no effect on the growth of bloodstream form cells, massive adverse effects on the levels of almost all mitochondrial RNAs were observed. These studies greatly expand our knowledge regarding the functions of MRP1/2 and RBP16 and suggest that both RNA-specific and life cycle stage-specific factors impact MRP1/2 and RBP16 functions.
