Evaluating Serum Proteome in Women with Obsessive-Compulsive Disorder/Bipolar Disorder Compared to Pure Obsessive- Compulsive Disorder Subjects and Healthy Controls.

OBJECTIVES

The present study aimed to evaluate the serum proteome of women with obsessive-compulsive disorder (OCD)/bipolar disorder (BP) compared to pure OCD subjects and healthy controls.

MATERIALS &

METHODS

Serum proteome of women with OCD/BP, pure OCD individuals, and healthy controls were subjected to 2DE-based proteomics accompanied with MALDI-TOF-TOF mass spectrometry. Further evaluation of the identified protein spots with the significance of p<0.05 and fold≥1.5 was done by applying protein interaction mapping via Cytoscape v. 5.3.1 and its plugins.

RESULTS

The results indicate that vitamin D binding protein (GC) and haptoglobin spots (HP) significantly changed expression in OCD and OCD/BP with different expression patterns. These identified spots may contribute to OCD/BP and act as differentially recognized biomarkers comparing pure OCD and OCD/BP.

CONCLUSION

The Findings imply that these proteins in the serum of the patients could be potential distinguishable biomarkers in clinical usage after related validation experiments. Therefore, this study provides a preliminary evaluation to understand OCD/BP proteome behavior better.
