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 DNA (mtDNA) heteroplasmies are associated with various diseases but the transmission of heteroplasmy from mtDNA to mitochondrial RNA (mtRNA) remains unclear. We compared heteroplasmies in mtRNA from 446 human B-lymphoblastoid cell lines to their corresponding mtDNA using deep sequencing data from two independent studies. We observed 2786 heteroplasmies presenting in both DNA and RNA at 1% frequency cutoff. Among them, the frequencies of 2427 (87.1%) heteroplasmies were highly consistent (less than 5% frequency difference) between DNA and RNA. To validate these frequency consistencies, we isolated DNA and RNA simultaneously from GM12282 cell line used in those two sequencing studies, and resequenced its heteroplasmy sites. Interestingly, we also observed the rapid changes of heteroplasmy frequencies during 4 weeks of the cell culture: the frequencies at Day 14 increased by >25% than those at Day 0. However, the heteroplasmy frequencies from the same time point were highly consistent. In summary, our analysis on public data together with in vitro study indicates that the heteroplasmies in DNA can be transcribed into RNA with high fidelity. Meanwhile, the observed rapid-changing heteroplasmy frequency can potentially disturb cell functions, which could be an overlooked confounding factor in cell line related studies.
