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

Elevated environmental zinc levels pose significant toxicity to biological systems, necessitating adaptive responses to mitigate excessive zinc exposure. In C. elegans, a specific lysosome-related organelle, the gut granule, may increase in number and volume with high dietary zinc, thereby lowering cytosolic zinc concentration, though the mechanisms remain unclear. Our results suggest that GLO-1 predominantly controls granule biogenesis, whereas zinc-induced granule expansion involves distinct mechanisms. Further study revealed that high zinc upregulated GLO-1 activity through its GEF complex GLO-3-CCZ-1, by enhancing transcription of GLO-3 and post-translational modification of CCZ-1. Zinc transporter CDF-2 has been identified to mediate zinc influx into gut granules. In this study, analysis of 14 C. elegans CDFs reveals that ZK185.5 (CDF-3) and F19C6.5 (CDF-4) also localize in gut granules. Functional studies suggest that CDF-3, not CDF-4, complements CDF-2 in facilitating zinc influx into gut granules. Unlike CDF-2, the expression of CDF-3 is downregulated in a high zinc diet. These results suggest a modulation in the composition of CDFs within gut granules in response to environmental zinc. Together, our study reveals a sophisticated zinc detoxification mechanism of C. elegans gut granule to uphold cytosolic zinc homeostasis amidst fluctuating environments.
