A study evaluates gene expression changes due to acute stress in male zebrafish, suggesting potential for future gender-specific research.

The study aims to identify gene expression changes in the brains of male zebrafish following exposure to acute stressors.
Conducted a stress trial with male zebrafish
Analyzed gene expression in various brain regions over time
Utilized qPCR to measure gene expression levels
Identified changes in immediate early genes and stress axis-related genes
Detected differences in expressions related to appetite and neurotransmitter pathways
Noted variation in gene responses across different brain regions

Pietsch et al. (2025) studied this question.
