Quantitative Super-Resolution Imaging of ER-Phagy Initiation in Cells.

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
Selective autophagy of the endoplasmic reticulum (ER-phagy) is a mechanism that is necessary for degrading damaged ER components and preventing cells from experiencing ER stress. Various ER-phagy receptors orchestrate this process by building protein assemblies with dedicated functions. In order to understand the molecular building principles of ER-phagy, it is important to reveal the assembly of ER-phagy receptors in a temporal and functional context. However, direct visualization is hampered by the diffraction limit in light microscopy. Super-resolution microscopy (SRM) can bypass this limitation and resolve single proteins and nanoscale protein clusters in cells. In particular, DNA points accumulation for imaging in nanoscale topography (DNA-PAINT) is a powerful technology that can resolve individual protein clusters in cells and provide information on their molecular composition. Here, we report a step-by-step protocol on how to utilize DNA-PAINT to perform super-resolution imaging of ER-phagy receptors in fixed cells. In addition, we provide a detailed explanation of image generation, cluster analysis, and molecular quantification.
