Abstract
Proteomic analyses facilitate the interpretation of molecular biomarker probes which are very helpful in diagnosing schizophrenia SZ In the current study we attempt to test whether potential differences in plasma protein expressions in SZ and bipolar disorder BD are associated with cognitive deficits and their underlying brain structures Fortytwo plasma proteins of 29 SZ patients 25 BD patients and 93 nonclinical controls were quantified and analysed using multiple reaction monitoringbased triple quadrupole mass spectrometry approach We also computed group comparisons of protein expressions between patients and controls and between SZ and BD patients as well Potential associations of protein levels with cognitive functioning psychomotor speed executive functioning crystallised intelligence as well as underlying brain volume in the hippocampus were explored using bivariate correlation analyses The main finding of this study was that apolipoprotein expression differed between patients and controls and that these alterations in both disease groups were putatively related to cognitive impairments as well as to hippocampus volumes However none of the protein level differences were related to clinical symptom severity In summary altered apolipoprotein expression in BD and SZ was linked to cognitive decline and underlying morphological changes in both disorders Our results suggest that the detection of molecular patterns in association with cognitive performance and its underlying brain morphology is of great importance for understanding of the pathological mechanisms of SZ and BD as well as for supporting the diagnosis and treatment of both disordersMRI was performed at the Frankfurt Brain Imaging Centre supported by the German Research Council DFG and the German Ministry for Education and Research BMBF Brain Imaging Center Frankfurt/Main DLR 01GO0203 We acknowledge the Brazilian National Council of Research CNPq for funding Dr Gilberto Alves who is supported by a postdoctoral scholarship from the CNPq Process 209981/20130 in an exchange cooperation programme with the Goethe University Frankfurt am Main Germany and Dr Andre F Carvalho who receives CNPq research fellowship awards level II Sabine Bahn is a Director and Jason D Cooper and Sureyya Ozcan are consultants of Psynova Neurotech None of the other authors report any conflict of interest Jason Cooper Sabine Bahn and Sureyya Ozcan would like to thank the Stanley Medical Research Institute for centre support The study was reviewed and approved by the ethics committee of the Faculty of medicine Goethe University Frankfurt/Main Germany
