dc.description.abstractObjective: The translocator protein (TSPO) has been implicated in numerous functions including steroid production and regulation of stress and anxiety. Cannabinoids have been shown to reduce plasma testosterone levels and alter anxiety levels. The aim of the present study was to determine whether the synthetic cannabinoid HU210 is able to regulate TSPO expression in several peripheral organs. Methods: HU210 (100 μg/kg) was administered intraperitoneally to both adult and adolescent male ratsfor 14 days. TSPO receptor expression in several organs, including the liver, spleen, kidneys and testes, was quantified by membrane receptor binding using the selective radiolig and, PK11195. In cases where receptor binding data indicated significant cannabinoid-induced differences, further RT-qPCR was carried out to determine the transcriptional regulation of the TSPO gene. Additionally, film-autography was used to identify potential changes in the spatial distribution of the TSPO tissue binding sites. Results: Results indicate that HU210 induces significant reductions in testicular TSPO expression in adult but not adolescent rats. No changes were found in other organs examined. These results are consistent with the previously observed effects of cannabinoids on testosterone production and a presumed role for TSPO in steroidogenesis. Conclusions: Overall, these results suggest that cannabinoids may alter testosterone production by altering the expression of testicular TSPO and that the alteration of TSPO occurs in an age-dependent manner.© 2014 Chan RHY, et al.en_AU
