Background:
Fibroblast growth factor (FGF) 2 (also referred to as basic FGF) is a multifunctional growth factor that plays a pivotal role in the pro-survival, pro-migration and pro-differentiation of neurons.
Method:
Because alterations in FGF2 levels are suggested to contribute to the pathogenesis schizophrenia, we investigated serum levels of FGF2 in the Gunn rat, a hyperbilirubinemia animal model of schizophrenic symptoms.
Results:
The enzyme-linked immunosorbent assay showed that the serum levels of FGF2 in Gunn rats were 5.09 ± 0.236 pg/mL, while those in the normal strain Wistar rats were 11.90 ± 2.142 pg/mL. The serum FGF2 levels in Gunn rats were significantly lower than those in Wistar rats. We also measured serum levels of unconjugated bilirubin (UCB) and found a significant negative correlation between UCB and FGF2 at serum levels in all the rats studied.
Conclusion:
Since it is known that FGF2 regulates dopaminergic neurons and have anti-neuroinflammatory effects, our finding suggests that low FGF2 levels may contribute to the pathogenesis of schizophrenia, in which disbalanced dopamin-ergic signaling and neuroinflammation are supposed to play certain roles.
