Abstract:
:In spite of evidence about negative effects of Nandrolone Decanoate (ND) on cognitive and memory performance, the underlying mechanisms are complex and have remained unclear. This research examines the role of Calcineurin in synaptic plasticity and memory storage impairment in ND administrated adolescent male rats. For behavioral study by passive avoidance learning and memory (PAL), adolescent male rats were treated with ND or ND plus selective Calcineurin antagonist (Tacrolimus), before retention test. ND significantly decreased the retrieval of PAL, whereas Tacrolimus plus ND had no significant effect on PAL. For electrophysiological study hippocampal slices were perfused by ND or ND plus Tacrolimus. The magnitude of fEPSP-LTP of ND perfused slices was less than the control and a reduction of fEPSP-PS (E-S) coupling was observed, while pre-administration of Tacrolimus abolished the ND impairment effect on fEPSP-LTP and E-S coupling. This study showed that ND may induce impairing effects on hippocampal area CA1 activity and plasticity and PAL memory storage through changes in the function of the Calcineurin.
