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

Oxidative stress serves as a fundamental mechanism contributing to ionizing radiation-induced damage, which has significant implications for tissue injury. Cysteine dioxygenase type 1 (CDO1) catalyzes the rate-limiting step for cysteine oxidation pathway, thereby playing a crucial role in regulating cellular cysteine availability. However, the regulation of CDO1 activity and cysteine oxidation under ionizing radiation, as well as their subsequent effects on cell viability, remains largely unexplored. In this study, we provide evidence that CDO1 activity and cysteine oxidation are inhibited following radiation exposure. Mechanistically, ionizing radiation-induced oxidative stress triggers glutathionylation of CDO1 at cysteine (C) 164, which impairs CDO1 enzymatic activity by disrupting its interaction with the substrate cysteine. Furthermore, glutathionylation at CDO1 C164 is essential for maintaining cellular redox homeostasis and supports cell viability under ionizing radiation. These findings reveal a novel mechanism through which redox modifications of CDO1 regulate cysteine metabolism and glutathione synthesis under oxidative stress, thereby underscoring its potential as a therapeutic target for addressing radiation-induced injuries.
