Abstract

The phytocannabinoid Δ⁹-Tetrahydrocannabinol (Δ⁹-THC), the main psychoactive cannabinoid in cannabis, activates a number of signalling cascades including p53. This study examines the role of Δ⁹-THC in regulating the p53 post-translational modifier proteins, Murine double minute (Mdm2) and Small Ubquitin-like MOdifier protein 1 (SUMO-1) in cortical neurons. Δ⁹-THC increased both Mdm2 and SUMO-1 protein expression and induced the deSUMOylation of p53 in a cannabinoid receptor type 1 (CB₁)-receptor dependent manner. We demonstrate that Δ⁹-THC decreased the SUMOylation of the CB₁ receptor. The data reveal a novel role for cannabinoid receptor activation in modulating the SUMO regulatory system. Structured summary: MINT-7266621: Cb1 (uniprotkb:P20272) physically interacts (MI:0915) with SUMO-1 (uniprotkb:Q5I0H3) by anti bait coimmunoprecipitation. (MI:0006)MINT-7266633: SUMO-1 (uniprotkb:Q5I0H3) and Cb1 (uniprotkb:P20272) colocalize (MI:0403) by fluorescence microscopy (MI:0416).
