The objective of the current study was to determine whether a low - dose subchronic DEX treatment ( 100 mu g / kg for 8 consecutive days ) exerts long - term effects on apoptosis in the adult rat prefrontal cortex ( PFC ) by examining the expression of cell death - promoting molecules ( poly ( ADP - ribose ) polymerase ( PARP ) , p53 , procaspase 3 , cleaved caspase 3 , Bax ) and cell - survival molecules ( AKT , Bcl - 2 ) .
