Description
Human umbilical vein endothelial cells (HUVECs) were transduced with either MIY-N1IC (Notch1 intracellular domain) or MIY vector control. The cells were sorted for YFP, and RNA was extracted using Trizol (Invitrogen) and analyzed by the Affymetrix Human Genome U133 Plus 2.0 Array. Results were analyzed using the GCRMA algorithm to identify genes with a minimum of 2-fold induction or reduction. This global gene expression study was used to identify Notch targets in the endothelium.
Publication Title
Notch initiates the endothelial-to-mesenchymal transition in the atrioventricular canal through autocrine activation of soluble guanylyl cyclase.

Description
Activation of the immune system is a way for host tissue to defend itself against tumor growth. Hence, treatment strategies that are based on immunomodulation are on the rise. Conventional cytostatic drugs such as the anthracycline doxorubicin can also activate immune cell functions of macrophages and natural killer cells. In addition, cytotoxicity of doxorubicin can be enhanced by combining this drug with the cytokine IFN-alpha. Although doxorubicin is one of the most applied cytostatics, the molecular mechanisms of its immunomodulation ability are not investigated thoroughly. In microarray analyses of HeLa cells, a set of 19 genes related to interferon signaling was significantly overrepresented among genes regulated by doxorubicin exposure including STAT-1, -2, IRF9, NMI, and caspase 1. Regulation of these genes by doxorubicin was verified with Real-Time PCR and immunoblotting. An enhanced secretion of IFN-alpha was observed when HeLa cells were exposed to doxorubicin as compared to untreated cells. IFN-alpha neutralizing antibodies and inhibitors of JAK-STAT signaling (ATA and AG490) significantly abolished doxorubicin-stimulated expression of interferon signaling-related genes. Furthermore, inhibition of JAK-STAT signaling significantly reduced doxorubicin induced caspase 3 activation and desensitized HeLa cells to doxorubicin cytotoxicity. In conclusion, we demonstrate that doxorubicin induces interferon-responsive genes via IFN-alpha-JAK-STAT1 signaling and that this pathway is relevant for doxorubicins cytotoxicity in HeLa cells. As immunomodulation is a promising strategy in anticancer treatment, this novel mode of action of doxorubicin may help to further improve the use of this drug among different types of anticancer treatment strategies.

Description
The transcription factor Pax6 acts as a key developmental regulator in various organs. In the developing brain Pax6 regulates patterning, neurogenesis and proliferation, but how these diverse effects are mediated at the molecular level is not well understood. As Pax6 regulates forebrain development including neurogenesis, proliferation and patterning, almost exclusively by one of its DNA-binding domains, the bipartite paired domain, we examined the role of its respective DNA-binding subdomains (PAI and RED). Using mice with point mutations in the PAI (Pax6Leca4, N50K) and RED (Pax6Leca2, R128C) subdomains we unravelled opposing roles of mutations in these subdomains in regulating genes that control proliferation in the developing cerebral cortex.

Functional dissection of the paired domain of Pax6 reveals molecular mechanisms of coordinating neurogenesis and proliferation.

Description
CD20 is a clinically validated target for Non-Hodgkins lymphomas and autoimmune diseases. Interactions of CD20 with the B cell receptor (BCR) and components of the BCR signaling cascade have been reported. In this study we show that antibodies against CD20 or activation of the BCR by specific antibodies induce very similar expression patterns of up- or down-regulated genes in NHL cell lines indicating that CD20 may play a role in BCR signaling and vice versa.

Description
Background: Several genetic defects of the nucleotide excision repair (NER) pathway, including deficiency of the Excision Repair Cross-Complementing rodent repair deficiency, complementation group 1 (ERCC1), result in pre-mature aging, impaired growth, microcephaly and delayed development of the cerebellum. Such a phenotype also occurs in ERCC1-knockout mice which survive for up to 4 weeks after birth. Therefore, we analyzed cerebellar and hippocamapal transcriptomes of these animals at 3 weeks of age to identify the candidate mechanisms underlying brain consequences of reduced ERCC1 activity.
Publication Title
Downregulation of cholesterol biosynthesis genes in the forebrain of ERCC1-deficient mice.
