The Claim
In larval zebrafish, early-life elevation of glucocorticoids is associated with reduced proopiomelanocortin (pomc) expression in the pituitary and increased fkbp5 expression, suggesting potential molecular mechanisms for altered regulation of the stress axis in this model organism.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When baby zebrafish have higher stress hormone levels early in life, it seems to change how certain genes in their brain work—turning down one gene linked to stress control and turning up another—hinting at how early stress might rewire their stress response system.

Early-life glucocorticoid elevation in larval zebrafish is associated with reduced expression of proopiomelanocortin (pomc) in the pituitary and increased expression of fkbp5, indicating potential molecular mechanisms underlying altered stress axis regulation in this model.
What the research says
1 studyThe study shows that raising stress hormone levels early in zebrafish larvae leads to changes in brain genes linked to stress control, which is exactly what the claim says happens.
