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

Copper oxide nanoparticles (CuONPs) have been widely applied, posing potential risks to human health. Although the toxicity of CuONPs on the liver and spleen has been reported, their effects on reproductive health remain unexplored. In this study, we investigate the effects of CuONPs on embryonic development and their potential mechanisms. Our results demonstrate that CuONPs exposure impairs mouse preimplantation embryonic development, particularly affecting the morula-to-blastocyst transition. Additionally, CuONPs were found to reduce the pluripotency of the inner cell mass (ICM) and mouse embryonic stem cells (mESCs). Mechanistically, CuONPs block autophagic flux and impair mitophagy, leading to the accumulation of damaged mitochondria. This mitochondrial dysfunction leads to reduced tricarboxylic acid (TCA) cycle activity and decreased α-ketoglutarate (α-KG) production. Insufficient α-KG induces the failure of DNA demethylation, reducing corresponding chromatin accessibility and consequently inhibiting ICM-specific genes expressions. Similar reduced development and inhibitions of pluripotency gene expression were observed in CuONPs-treated human blastocysts. Moreover, in women undergoing assisted reproductive technology (ART), a negative correlation was found between urinary Cu ion concentrations and clinical outcomes. Collectively, our study elucidates the mitophagy-mediated metabolic mechanisms of CuONPs embryotoxicity, improving our understanding of the potential reproductive toxicity associated with it.
