Abstract
Bipolar disorder (BD) is a severe psychiatric disorder characterized by alternating manic and depressive episodes. The molecular mechanisms underlying the transition between mania and depression remain unclear. Utilizing a mania animal model induced by ouabain, we observed reduced phosphorylated level of cyclic AMP-responsive element-binding protein (pCREB) and Period (PER)2 expression in the cornu ammonis (CA1) region of the hippocampus, which were restored by lithium treatment. shRNA knockdown of CREB or Per2 in CA1 region induced mania-like behavior, while overexpression of both factors resulted in depression-like behavior. Furthermore, our protein analyses revealed that the upregulation or downregulation of CREB or Per2 influenced each other's expression. Co-immunoprecipitation results demonstrated that CREB interacts with PER2. Taken together, our data suggest for potential inter-regulatory crosstalk between CREB-PER2 in hippocampal CA1 region, which mediates the transition between mania- and depression-like behaviors.
期刊介绍：
Neuropsychopharmacology is a reputable international scientific journal that serves as the official publication of the American College of Neuropsychopharmacology (ACNP). The journal's primary focus is on research that enhances our knowledge of the brain and behavior, with a particular emphasis on the molecular, cellular, physiological, and psychological aspects of substances that affect the central nervous system (CNS). It also aims to identify new molecular targets for the development of future drugs.
The journal prioritizes original research reports, but it also welcomes mini-reviews and perspectives, which are often solicited by the editorial office. These types of articles provide valuable insights and syntheses of current research trends and future directions in the field of neuroscience and pharmacology.
