Zinc transporter ZnT3/Slc30a3 has a potential role in zinc ion influx in mouse oocytes.

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
Zinc is an essential trace element for various physiological functions, including reproduction. The influx/efflux of zinc ions is regulated by zinc transporters (Zip1-14 and ZnT1-8, 10). However, the precise roles of zinc transporters and zinc dynamics in reproductive functions are unknown. In this study, ZnT3/Slc30a3 gene knockout (KO) mice were used to analyze the role of ZnT3. In ZnT3 KO mice, intracellular zinc ions in oocytes/zygotes were significantly reduced compared to those in controls, and free zinc ions did not accumulate in the oocyte cytoplasm. However, fertilization of these oocytes and the average litter size were comparable to those of control mice. Our results suggest that ZnT3 plays an important role in the accumulation of zinc ions in oocytes but not in the developmental ability of mice. ZnT3 KO mice will be useful for examining zinc dynamics in oocytes and other tissues.
