Prefrontal cortex transcriptome of Arid1b heterozygote mutantation mice and drug treated-mice age of postnatal day 120
Arid1b is a chromatin remodeler implicated in neurodevelopmental disorders. Arid1b mutant mice with haploinsufficiency (Arid1b HT) displayed persistent excitatory synaptic dysfunction from juvenile to adult stage, decreased synaptic density and transmission. Moreover, they showed autistic-like behaviors in both of early and adult stages, decreased sociability in pup USV calling and adult social interaction, and adult repetitive grooming. We found that early chronic fluoxetine treatment could carry out long-lasting restoration in electrophysiological and behavioral deficits in Arid1b HT mice. Prefrontal cortex specific transcriptomic analysis with mice at postnatal day 120 which underwent chronic fluoxetine treatment from postnatal day 3 to postnatal day 21 via mammillary milk was done to investigate transcriptomic reprogramming which contributes to this restoration.
