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

As a selective degradation system, chaperone-mediated autophagy (CMA) is essential for maintaining cellular homeostasis and survival under stress conditions. Increasing evidence points to an important role for the dysfunction of CMA in the pathogenesis of Parkinson disease (PD). However, the mechanisms by which CMA regulates neuronal survival under stress and its role in neurodegenerative diseases are not fully understood. PARK7/DJ-1 is an autosomal recessive familial PD gene. PARK7 plays a critical role in antioxidative response and its dysfunction leads to mitochondrial defects. In the current study, we showed that CMA mediated the lysosome-dependent degradation of PARK7. Importantly, CMA preferentially removed the oxidatively damaged nonfunctional PARK7 protein. Furthermore, CMA protected cells from mitochondrial toxin MPP(+)-induced changes in mitochondrial morphology and function, and increased cell viability. These protective effects were lost under PARK7-deficiency conditions. Conversely, overexpression of PARK7 significantly attenuated the mitochondrial dysfunction and cell death exacerbated by blocking CMA under oxidative stress. Thus, our findings reveal a mechanism by which CMA protects mitochondrial function by degrading nonfunctional PARK7 and maintaining its homeostasis, and dysregulation of this pathway may contribute to the neuronal stress and death in PD pathogenesis.
