The objective of this study was to determine the effects of suppression of allopregnanolone levels on the markers of development and functional outcome. Pregnant guinea pigs were treated with finasteride at a dose (25 mg/kg maternal weight) shown to suppress allopregnanolone between 60 days of gestation until delivery (term ~71 days). The cerebella from neonates, whose mothers were treated with finasteride or vehicle during pregnancy, were collected at postnatal age 8. Pups that received finasteride displayed significantly greater glial fibrillary acid protein area coverage and reduced GABAA receptor a α₆-subunit messenger RNA within the cerebellum than pups that were exposed to vehicle. These findings indicate that loss of neurosteroid action on the foetal brain in late gestation produces prolonged astrocyte activation and reductions in GABAA receptor a α₆-subunit expression. These changes may contribute to the long-term changes in function associated with preterm birth.]]> Thu 16 Aug 2018 13:35:57 AEST ]]> Allopregnanolone in the brain: protecting pregnancy and birth outcomes https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:16514 Sat 24 Mar 2018 08:04:18 AEDT ]]>
