Repeated exposure to ketamine leads to mental behavioral disorders and cognitive deficits in mice. As a neurotransmitter receptor, dopamine receptor 1 (DRD1) is involved in mental regulation and memory formation. However, the role of DRD1 in ketamine's behavioral disorder and neurotoxicity remains unclear. We found that seven-day ketamine exposure induced anxiety-like, depressive-like behavior...

Psychotic disorders frequently result from repeated ketamine exposure, yet the underlying mechanisms remain elusive. We propose that repeated exposure to ketamine may induce psychotic-like behaviors via DRD1-mediated nuclear signaling pathways. Our investigation focused on phosphorylated DARPP-32 at Thr34, Thr75, and Ser97, alongside transcriptome profiling in both cell and mouse models. We...

Psychotic disorder is a significant consequence of ketamine abuse. However, the molecular mechanisms and biomarkers for this psychotic disorder and associated long-term cognitive impairment remain unclear. To investigate the behavioral changes and comprehensive gene expression alterations in mice following ketamine administration, we employed behavioral testing and RNA sequencing (RNA-seq). We...

The abnormal expression of the dopamine D1 receptor (DRD1) may be associated with schizophrenia. MicroRNAs (miRNAs) can post-transcriptionally regulate DRD1 expression. Here, we established a ketamine-induced schizophrenia-like behavior mouse model and investigated the changes in miR-15a-3p, miR-15b-3p, miR-16-1-3p, and DRD1 in response to ketamine. Administration of high-dose ketamine for...
