QUANTITATIVE SUBCELLULAR PROTEOMICS OF THE ORBITOFRONTAL CORTEX OF SCHIZOPHRENIA PATIENTS

We analyzed OFC post-mortem brain tissue from patients classified as residual schizophrenia according to the DMS-IV manual. In this classification, the patients do not manifest prominent positive psychotic symptoms but prevail characteristic disturbance of negative symptoms. Through the comparison of patient´s samples against a pool of control subjects without any history of psychiatric illness we generated an organellar proteome map from different subcellular fractions such as mitochondria (MIT), crude nuclear fraction (NUC) and cytoplasm (CYT) with the aim to monitor the subproteome changes using iTRAQ labelling for relative quantification and Selected Reaction Monitoring (SRM) for targeted quantification.
