Description
Bipolar disorder is a severe and heritable psychiatric disorder and affects up to 1% of the population worldwide. Lithium is recommended as first-line treatment for the maintenance treatment of bipolar-affective disorder in current guidelines, its molecular modes of action are however poorly understood.

Description
In a whole-transcriptome study, cellular responses of DCs and macrophages confronted with the fungi A. fumigatus, platelet rich plasma (PRP) or the combination of A.fumigatus and PRP were investigated. Therefore DCs and macrophages of three independent donors were harvested after 6 hours co-culture with A. fumigatus, platelet rich plasma (PRP) or the combination of A.fumigatus and PRP and analyzed with Affymetrix whole genome expression arrays. In general, transcriptomic analysis revealed a cell type dependent clustering. Only little effects were obeserved by addition of PRP. Furthermore a clustering of A.fumigatus stimulated cells whether PRP was present or not, was observed. However, significant differences in the immune response of A.fumigauts stimuled DC and macrophages were determined.

Description
In a whole-transcriptome study, cellular responses of DCs confronted with the fungi A. fumigatus, C. albicans or the bacterial cell wall component LPS were investigated. Therefore DCs of four independent donors were analyzed after 6 hours co-culture with A. fumigatus, C. albicans and LPS by Affymetrix whole genome expression arrays. In general, transcriptomic analysis revealed a clustering of the A. fumigatus and C. albicans stimulated DCs. However, LPS and fungi-dependent gene expression showed more common similarities compared to the untreated control. Stimulation with LPS induced a differential regulation of 2793 genes after 6h, while confrontation with A. fumigatus and C. albicans resulted in 743 and 974 differentially regulated genes, respectively. Kruppel-like factor 4 (KLF4) was identified as the only transcription factor that was down-regulated in DCs by both fungi but induced by stimulation with LPS.

Description
In a whole-transcriptome study, cellular responses of DCs confronted with the fungi A. fumigatus, C. albicans or the bacterial cell wall component lipopolysaccharide (LPS) were investigated. Therefore, DCs of four independent donors were harvested after 12 hours co-culture with A. fumigatus, C. albicans and LPS and analyzed with Affymetrix whole genome expression arrays. In general, transcriptomic analysis revealed a clustering of the A. fumigatus- and C. albicans-stimulated DCs. However, LPS and fungi-dependent gene expression showed more common similarities compared to the untreated control.

Description
WNT-induced secreted protein 1 (WISP1/CCN4), a member of the CCN protein family, acts as a downstream factor of the canonical WNT-signaling pathway. A dysregulated expression of WISP1 often reflects its oncogenic potential by inhibition of apoptosis, a necessary form of cell death that protect cell populations for transformation into malignant phenotypes. WISP1-signaling is also known to affect proliferation and differentiation of human mesenchymal stem cells (hMSCs), which are fundamental for the constitution and maintenance of the musculoskeletal system. Our study emphasizes the importance of WISP1-signaling for cell survival of primary human cells. Therefore, we established a successful down-regulation of endogenous WISP1 transcripts through gene silencing in hMSCs. We were able to demonstrate the consequence of cell death immediately after WISP1 down-regulation took place. Bioinformatical analyses of subsequent performed microarrays from WISP1 down-regulated vs. control samples confirmed this observation. We uncovered several clusters of differential expressed genes important for cellular apoptosis induction and immuno-regulatory processes, thereby indicating TRAIL-induced and p53-mediated apoptosis as well as IFNbeta-signaling. Since all of them act as potent inhibitors for malignant cell growth, in vitro knowledge about the connection with WISP1-signaling could help to find new therapeutic approaches concerning cancerogenesis and tumor growth in musculoskeletal tissues.

Description
DCs are localized under the mucosa of the lungs and the gastrointestinal tract, and therefore come into close contact with A. fumigatus germ tubes during early steps of infection as soon as fungi become invasive. For a more detailed insight into differentially regulated genes, whole genome microarray analysis was performed.

Description
DAC represents a therapeutic option for elderly AML patients. However, there is still a lack of data for valid biomarkers in respect to response. We executed a gene expression analysis prior to treatment to evaluate gene expression patterns associated with response that might be used to predict DAC therapy outcome. In our cohort an objective ORR of 27% was seen. In a class comparison analysis 333 genes were identified that correlated significantly with response. In this gene signature genes that were prior associated with adverse outcome to regular chemotherapy were enriched in the response group. Interistingly for the non response cohort TSG showed an increased expression, suggesting that epigenetic silencing due to promoter hypermethylation might play a lesser role in theses leukemia pathogenesis.
