Abstract
Reserpine is a drug that is commonly used as an antihypertensive and antipsychotic drug in clinical practice. During our previous research, we found that reserpine treatment in zebrafish larvae can cause depression-like behaviors, but the corresponding mechanisms are still unclear. In this study, we aimed to investigate the molecular mechanism by which reserpine exposure affects locomotor behaviors in larval zebrafish through transcriptome analysis. The gene enrichment results showed that the differentially highly expressed genes of zebrafish are mainly enriched in voltage-gated ion channels, dopaminergic synapses and wnt signaling pathways. Selected genes (apc2, cacna1aa, drd2b, dvl1a, fzd1, wnt1, wnt3a, wnt9a and wnt10a) by transcriptomic results was validated by real-time PCR. Consistently, Wnt signaling pathway inhibitor XAV939 may induce reduced behavioral changes in zebrafish larvae, while the Wnt signaling pathway agonist SB415286 reversed the reserpine-induced depressive effects. Our study provides gene transcriptional profile data for future research on reserpine-induced locomotor behavioral changes.
