Assays

Proteomics: brain tissues coming from both human PFC and the 4 different mouse models were prepared as follows. Tissues were grinded with a biomasher using 350 µL of MeOH:H2O (4:1). Protein pellets were resuspended in 200 µL Laemmli buffer (10% SDS, Tris 1M pH 6.8, glycerol) then centrifuged at 11.135 rpm at 4°C for 5 minutes. Protein concentration was determined using DC assay (BioRad, Hercules, CA, USA) according to the manufacturer’s instructions. 100 µg of protein lysate for each sample were ...

Phosphoproteomics: starting from the protein extracts from the global proteomics experiments, proteases inhibitors (Sigma, P8340) and phosphatases inhibitors (final concentration in Na3VO4 = 1 mM) were added to all samples. Protein concentration was determined using RC-DC assay (BioRad, Hercules, CA, USA) according to the manufacturer’s instructions. 250 µg of proteins for each sample were reduced and alkylated prior to an in-house optimized single-pot, solid-phase-enhanced sample preparation ...
