FOXO3a/PI3K/Akt pathway participates in the ROS- induced apoptosis triggered by α-ZEL and β-ZEL.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Zearalenone (ZEN), an estrogenic mycotoxin, is one of the most common food and feed contaminants. Also, its metabolites α-zearalenol (α-ZEL) and β-zearalenol (β-ZEL) are considered to induce oxidative stress, however its effect in prostate cells is not known yet. Our previous observations showed that forehead box transcription factor 3a (FOXO3a) expression is modified in hormone- sensitive cells in the response to mycotoxins, similar to the phosphoinositide 3-kinase (PI3K)/ protein kinase B (Akt) pathway. Thus, this study evaluated the direct molecular effect of α-ZEL and β-ZEL in a dose of 30 µM in hormone-dependent human prostate cancer (PCa) cells with the focus of the involvement of FOXO3a and PI3K/Akt signaling pathway in that effect. We observed that both active metabolites of ZEN reduced cell viability, induced oxidative stress, cell cycle arrest and apoptosis in PCa cells. Furthermore, we observed that FOXO3a as well as PI3K/Akt signaling pathway participate in ZELs induced toxicity in PCa cells, indicating that this signaling pathway might be a regulator of mycotoxin-induced toxicity generally.
