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

Autophagy is a conserved, degradative process that has been implicated in a number of human diseases and is a potential target for therapeutic intervention. It is therefore important that we develop a thorough understanding of the mechanisms regulating this trafficking pathway. The Atg1 protein kinase is a key element of this control as a number of signaling pathways target this enzyme and its associated protein partners. These studies have established that Atg1 activities are controlled, at least in part, by protein phosphorylation. To further this understanding, we used a combined mass spectrometry and molecular biology approach to identify and characterize additional sites of phosphorylation in the Saccharomyces cerevisiae Atg1. Fifteen candidate sites of phosphorylation were identified, including nine that had not been noted previously. Interestingly, our data suggest that the phosphorylation at one of these sites, Ser-34, is inhibitory for both Atg1 kinase activity and autophagy. This site is located within a glycine-rich loop that is highly conserved in protein kinases. Phosphorylation at this position in several cyclin-dependent kinases has also been shown to result in diminished enzymatic activity. In addition, these studies identified Ser-390 as the site of autophosphorylation responsible for the anomalous migration exhibited by Atg1 on SDS-polyacrylamide gels. Finally, a mutational analysis suggested that a number of the sites identified here are important for full autophagy activity in vivo. In all, these studies identified a number of potential sites of regulation within Atg1 and will serve as a framework for future work with this enzyme.
