As brain-derived neurotrophic factor (BDNF) and its receptor trkB are linked to the etiology and treatment of mood disorders, we examined the effects of acute and long-term treatment of mood-stabilizer lithium on trkB activation and signaling and BDNF levels in the mouse anterior cingulate cortex (AC) and hippocampus (HC). The trkB activity was measured(More)
Antidepressants protect against hippocampal volume loss in humans and reverse stress-induced atrophic changes in animals thus supporting the hypothesis that the pathophysiology of stress-related disorders such as depression involves reductions in neuronal connectivity and this effect is reversible by antidepressant treatment. However, it is unclear which(More)
We have investigated gene expression changes produced by acute and chronic daily treatment with a prototypical antidepressant, imipramine, using DNA microarrays. The analysis of similarities in gene expression patterns among functionally related genes revealed four expression profile cluster areas that showed a highly significant overrepresentation of(More)
Available treatment for Parkinson’s disease (PD) is mainly symptomatic instead of halting or reversing degenerative processes affecting the disease. Research on the molecular pathogenesis of PD has suggested reduced trophic support as a possible cause or mediator of neurodegeneration. In animal models of the disease, neurotrophic factors prevent(More)
Brain-derived neurotrophic factor (BDNF) regulates neuronal survival, differentiation and plasticity. It has been shown to promote epileptogenesis and transgenic mice with decreased and increased BDNF signaling show opposite alterations in epileptogenesis. However, the mechanisms of BDNF action are largely unknown. We studied the gene expression changes 12(More)
High-throughput genomic measurements, interpreted as cooccurring data samples from multiple sources, open up a fresh problem for machine learning: What is in common in the different data sets, that is, what kind of statistical dependencies are there between the paired samples from the different sets? We introduce a clustering algorithm for exploring the(More)
MOTIVATION Cell-biological processes are regulated through a complex network of interactions between genes and their products. The processes, their activating conditions and the associated transcriptional responses are often unknown. Organism-wide modeling of network activation can reveal unique and shared mechanisms between tissues, and potentially as yet(More)
