Acute Valproate Exposure Induces Sex-Specific Changes in Steroid Hormone Metabolism in the Cerebral Cortex of Juvenile Mice.

In this study, VPA-induced acute metabolic alterations were investigated using liquid chromatography-tandem mass spectrometry in prepubertal mice brain. In VPA-treated (400 mg/kg in saline solution, intraperitoneal) mice, cortisol levels were increased (female: P < 0.004, male: P < 0.003) and 17β-estradiol levels were decreased (Both P < 0.03). Furthermore, in the VPA-treated male mice, dihydrotestosterone levels were increased (P < 0.02) and testosterone were decreased (P < 0.002). The 4-hydroxylase activity was upregulated in the female VPA-treated mice (P < 0.01) and the 5α-reductase activity was increased in the male VPA-treated mice (P < 0.003). These results indicate sex specific differences in VPA-induced steroid metabolism in the brain cortex. PMID: 32601984 [PubMed - as supplied by publisher]
