Investigating the Succinylome and Malonylome of Schizophrenia


ABSTRACT: The succinylome and malonylome of human oligodendrocyte precursors (MO3.13 line) and postmortem brain tissue (whole lysates and mitochondrial enrichments) were studied with shotgun mass spectrometry. The goal was to determine what changes in oligodendrocytes are induced with the addition of the NMDA receptor antagonist MK-801 and compare this with schizophrenia brain tissue; to visualize the changes that antipsychotics have on the succinylome and malonylome and how this may relate to their side effects; to see what changes induced by MK-801 are returned to more control-like levels and how this may relate to mechanisms of drug action; and to see what changes in these PTMs may exist in vivo in patients with schizophrenia compared to healthy controls.

The number of mass spectrometry (MS)-based proteomics datasets in the public domain keeps increasing, particularly those generated by Data Independent Acquisition (DIA) approaches such as SWATH-MS. Unlike Data Dependent Acquisition datasets, the re-use of DIA datasets has been rather limited to date, despite its high potential, due to the technical challenges involved. We introduce a (re-)analysis pipeline for public SWATH-MS datasets which includes a combination of metadata annotation protocols  ...[more]
