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

Defective mitochondria exert deleterious effects on host cells. To manage this risk, mitochondria display several lines of quality control mechanisms: mitochondria-specific chaperones and proteases protect against misfolded proteins at the molecular level, and fission/fusion and mitophagy segregate and eliminate damage at the organelle level. An increase in unfolded proteins in mitochondria activates a mitochondrial unfolded protein response (UPR(mt)) to increase chaperone production, while the mitochondrial kinase PINK1 and the E3 ubiquitin ligase PARK2/Parkin, whose mutations cause familial Parkinson disease, remove depolarized mitochondria through mitophagy. It is unclear, however, if there is a connection between those different levels of quality control (QC). Here, we show that the expression of unfolded proteins in the matrix causes the accumulation of PINK1 on energetically healthy mitochondria, resulting in mitochondrial translocation of PARK2, mitophagy and subsequent reduction of unfolded protein load. Also, PINK1 accumulation is greatly enhanced by the knockdown of the LONP1 protease. We suggest that the accumulation of unfolded proteins in mitochondria is a physiological trigger of mitophagy.
