Attenuated Notch signaling in schizophrenia and bipolar disorder.


ABSTRACT: The Notch signaling pathway plays a crucial role in neurodevelopment and in adult brain homeostasis. We aimed to further investigate Notch pathway activity in bipolar disorder (BD) and schizophrenia (SCZ) by conducting a pathway analysis. We measured plasma levels of Notch ligands (DLL1 and DLK1) using enzyme immunoassays in a large sample of patients (SCZ n?=?551, BD n?=?246) and healthy controls (HC n?=?639). We also determined Notch pathway related gene expression levels by microarray analyses from whole blood in a subsample (SCZ n?=?338, BD n?=?241 and HC n?=?263). We found significantly elevated Notch ligand levels in plasma in both SCZ and BD compared to HC. Significant gene expression findings included increased levels of RFNG and KAT2B (p?
