A Ribonucleoprotein Supercomplex Involved in trans-Splicing of Organelle Group II Introns.
Article in The Journal of biological chemistry, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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.
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 the chloroplast of the green alga Chlamydomonas reinhardtii, two discontinuous group II introns, psaA-i1 and psaA-i2, splice in trans, and thus their excision process resembles the nuclear spliceosomal splicing pathway. Here, we address the question whether fragmentation of trans-acting RNAs is accompanied by the formation of a chloroplast spliceosome-like machinery. Using a combination of liquid chromatography-mass spectrometry (LC-MS), size exclusion chromatography, and quantitative RT-PCR, we provide the first characterization of a high molecular weight ribonucleoprotein apparatus participating in psaA mRNA splicing. This supercomplex contains two subcomplexes (I and II) that are responsible for trans-splicing of either psaA-i1 or psaA-i2. We further demonstrate that both subcomplexes are associated with intron RNA, which is a prerequisite for the correct assembly of subcomplex I. This study contributes further to our view of how the eukaryotic nuclear spliceosome evolved after bacterial endosymbiosis through fragmentation of self-splicing group II introns into a dynamic, protein-rich RNP machinery.
