[O]ur results showed that [finasteride] treatment affected the expression of a number of accumbal proteins involved in key functional processes, such as regulation of GABAergic neurotransmission, as well as steroid and pyrimidine metabolism. These findings may prove crucial to understanding the neurochemical mechanisms of FIN’s neuropsychiatric side effects.
