| Outline of Final Research Achievements |
We collected bioresource including blood and cerebrospinal fluid (CSF) and performed omics analyses in patients with major depressive disorder (MDD), bipolar disorder, schizophrenia, and controls to find biomarkers for diagnosis and severity for the disorders. Based on proteomics approach, we found that CSF fibrinogen levels are increased in a portion of patients with MDD. We also examined the association between CSF protein levels and genetic variations (genome-wide polymorphisms) and constructed a database showing the relationship between CSF protein levels and single nucleotide polymorphisms (SNPs). We also found promising molecules from more than 2000 microRNA molecules as a biomarker for psychiatric diseases. Based on transcriptome approach on peripheral blood samples, we found that expression of some genes (VAMP2, FKBP4, and CRHR2) are altered in drug naive patients with MDD, suggesting that these genes could be biomarkers for MDD.
